+          The Extended Industry Standard Architecture (EISA) bus was
+          developed as an open alternative to the IBM MicroChannel bus.
+
+          The EISA bus provided some of the features of the IBM MicroChannel
+          bus while maintaining backward compatibility with cards made for
+          the older ISA bus.  The EISA bus saw limited use between 1988 and

+          it here. The emulator will then "only" calculate with a 64 bit
+          mantissa and round slightly incorrect, what is more then enough
+          for normal usage.
+
+config M68KFPU_EMU_ONLY
+        bool "Math emulation only kernel"
+        depends on M68KFPU_EMU
+        help
+          This option prevents any floating-point instructions from being
+          compiled into the kernel, thereby the kernel doesn't save any
+          floating point context anymore during task switches, so this
+          kernel will only be usable on machines without a floating-point
+          math coprocessor. This makes the kernel a bit faster as no tests
+          needs to be executed whether a floating-point instruction in the

+config ADVANCED
+        bool "Advanced configuration options"
+        ---help---
+          This gives you access to some advanced options for the CPU. The

+          it possible for you to improve performance somewhat if you know what
+          you are doing.
+
+          Note that the answer to this question won't directly affect the
+          kernel: saying N will just cause the configurator to skip all
+          the questions about these options.
+
+          Most users should say N to this question.
+
+config RMW_INSNS
+        bool "Use read-modify-write instructions"
+        depends on ADVANCED
+        ---help---
+          This allows to use certain instructions that work with indivisible
+          read-modify-write bus cycles. While this is faster than the
+          workaround of disabling interrupts, it can conflict with DMA
+          ( = direct memory access) on many Amiga systems, and it is also said
+          to destabilize other machines. It is very likely that this will
+          cause serious problems on any Amiga or Atari Medusa if set. The only
+          configuration where it should work are 68030-based Ataris, where it
+          apparently improves performance. But you've been warned! Unless you

+        bool "Use write-through caching for 68060 supervisor accesses"
+        depends on ADVANCED && M68060
+        ---help---
+          The 68060 generally uses copyback caching of recently accessed data.
+          Copyback caching means that memory writes will be held in an on-chip
+          cache and only written back to memory some time later.  Saying Y
+          here will force supervisor (kernel) accesses to use writethrough
+          caching.  Writethrough caching means that data is written to memory
+          straight away, so that cache and memory data always agree.
+          Writethrough caching is less efficient, but is needed for some
+          drivers on 68060 based systems where the 68060 bus snooping signal
+          is hardwired on.  The 53c710 SCSI driver is known to suffer from

+          Some Atari 68k machines (including the 520STF and 1020STE) divide

+
+          This enables support for using (parts of) ST-RAM as swap space,

+          performance if you have lots of alternate RAM (compared to the size

+          memory. ST-RAM will remain as ultra-fast swap space. On the other

+          Even if you say Y here, the currently visible virtual console
+          (/dev/tty0) will still be used as the system console by default, but
+          you can alter that using a kernel command line option such as
+          "console=ttyS1". (Try "man bootparam" or see the documentation of
+          your boot loader (lilo or loadlin) about how to pass options to the
+          kernel at boot time.)
+
+          If you don't have a VGA card installed and you say Y here, the
+          kernel will automatically use the first serial line, /dev/ttyS0, as
+          system console.

+ *
+ * 11/07/96: rewritten interrupt handling, irq lists are exists now only for
+ *           this sources where it makes sense (VERTB/PORTS/EXTER) and you must
+ *           be careful that dev_id for this sources is unique since this the
+ *           only possibility to distinguish between different handlers for
+ *           free_irq. irq lists also have different irq flags:
+ *           - IRQ_FLG_FAST: handler is inserted at top of list (after other
+ *                           fast handlers)
+ *           - IRQ_FLG_SLOW: handler is inserted at bottom of list and before
+ *                           they're executed irq level is set to the previous
+ *                           one, but handlers don't need to be reentrant, if
+ *                           reentrance occurred, slow handlers will be just
+ *                           called again.
+ *           The whole interrupt handling for CIAs is moved to cia.c
+ *           /Roman Zippel
+ *
+ * 07/08/99: rewamp of the interrupt handling - we now have two types of
+ *           interrupts, normal and fast handlers, fast handlers being
+ *           marked with SA_INTERRUPT and runs with all other interrupts
+ *           disabled. Normal interrupts disable their own source but
+ *           run with all other interrupt sources enabled.
+ *           PORTS and EXTER interrupts are always shared even if the
+ *           drivers do not explicitly mark this when calling
+ *           request_irq which they really should do.
+ *           This is similar to the way interrupts are handled on all
+ *           other architectures and makes a ton of sense besides
+ *           having the advantage of making it easier to share
+ *           drivers.

+ * arch/m68k/atari/ataints.c -- Atari Linux interrupt handling code
+ *
+ * 5/2/94 Roman Hodek:
+ *  Added support for TT interrupts; setup for TT SCU (may someone has
+ *  twiddled there and we won't get the right interrupts :-()
+ *
+ *  Major change: The device-independent code in m68k/ints.c didn't know
+ *  about non-autovec ints yet. It hardcoded the number of possible ints to
+ *  7 (IRQ1...IRQ7). But the Atari has lots of non-autovec ints! I made the
+ *  number of possible ints a constant defined in interrupt.h, which is
+ *  47 for the Atari. So we can call request_irq() for all Atari interrupts
+ *  just the normal way. Additionally, all vectors >= 48 are initialized to
+ *  call trap() instead of inthandler(). This must be changed here, too.
+ *
+ * 1995-07-16 Lars Brinkhoff <f93labr@dd.chalmers.se>:
+ *  Corrected a bug in atari_add_isr() which rejected all SCC
+ *  interrupt sources if there were no TT MFP!
+ *
+ * 12/13/95: New interface functions atari_level_triggered_int() and
+ *  atari_register_vme_int() as support for level triggered VME interrupts.
+ *
+ * 02/12/96: (Roman)
+ *  Total rewrite of Atari interrupt handling, for new scheme see comments
+ *  below.
+ *
+ * 1996-09-03 lars brinkhoff <f93labr@dd.chalmers.se>:
+ *  Added new function atari_unregister_vme_int(), and
+ *  modified atari_register_vme_int() as well as IS_VALID_INTNO()
+ *  to work with it.
+ *
+ * This file is subject to the terms and conditions of the GNU General Public
+ * License.  See the file COPYING in the main directory of this archive

+/*
+ * Atari interrupt handling scheme:
+ * --------------------------------
+ *
+ * All interrupt source have an internal number (defined in
+ * <asm/atariints.h>): Autovector interrupts are 1..7, then follow ST-MFP,
+ * TT-MFP, SCC, and finally VME interrupts. Vector numbers for the latter can
+ * be allocated by atari_register_vme_int().
+ *
+ * Each interrupt can be of three types:
+ *
+ *  - SLOW: The handler runs with all interrupts enabled, except the one it
+ *    was called by (to avoid reentering). This should be the usual method.
+ *    But it is currently possible only for MFP ints, since only the MFP
+ *    offers an easy way to mask interrupts.
+ *
+ *  - FAST: The handler runs with all interrupts disabled. This should be used
+ *    only for really fast handlers, that just do actions immediately
+ *    necessary, and let the rest do a bottom half or task queue.
+ *
+ *  - PRIORITIZED: The handler can be interrupted by higher-level ints
+ *    (greater IPL, no MFP priorities!). This is the method of choice for ints
+ *    which should be slow, but are not from a MFP.
+ *
+ * The feature of more than one handler for one int source is still there, but
+ * only applicable if all handers are of the same type. To not slow down
+ * processing of ints with only one handler by the chaining feature, the list
+ * calling function atari_call_irq_list() is only plugged in at the time the
+ * second handler is registered.
+ *
+ * Implementation notes: For fast-as-possible int handling, there are separate
+ * entry points for each type (slow/fast/prio). The assembler handler calls
+ * the irq directly in the usual case, no C wrapper is involved. In case of
+ * multiple handlers, atari_call_irq_list() is registered as handler and calls
+ * in turn the real irq's. To ease access from assembler level to the irq
+ * function pointer and accompanying data, these two are stored in a separate
+ * array, irq_handler[]. The rest of data (type, name) are put into a second
+ * array, irq_param, that is accessed from C only. For each slow interrupt (32
+ * in all) there are separate handler functions, which makes it possible to
+ * hard-code the MFP register address and value, are necessary to mask the
+ * int. If there'd be only one generic function, lots of calculations would be
+ * needed to determine MFP register and int mask from the vector number :-(
+ *
+ * Furthermore, slow ints may not lower the IPL below its previous value
+ * (before the int happened). This is needed so that an int of class PRIO, on
+ * that this int may be stacked, cannot be reentered. This feature is
+ * implemented as follows: If the stack frame format is 1 (throwaway), the int
+ * is not stacked, and the IPL is anded with 0xfbff, resulting in a new level
+ * 2, which still blocks the HSYNC, but no interrupts of interest. If the
+ * frame format is 0, the int is nested, and the old IPL value can be found in
+ * the sr copy in the frame.

+ * processor can't fetch it!). For that, the code first jumps to the
+ * jump statement with the (virtual) address of the pmove section in
+ * an address register . The jump statement is surely in the cache
+ * now. After that, that physical address of the reset code is loaded
+ * into the same address register, pmove is done and the same jump

+ *
+ * New version of ST-Ram buffer allocation. Instead of using the
+ * 1 MB - 4 KB that remain when the ST-Ram chunk starts at $1000
+ * (1 MB granularity!), such buffers are reserved like this:
+ *
+ *  - If the kernel resides in ST-Ram anyway, we can take the buffer
+ *    from behind the current kernel data space the normal way
+ *    (incrementing start_mem).
+ *
+ *  - If the kernel is in TT-Ram, stram_init() initializes start and
+ *    end of the available region. Buffers are allocated from there
+ *    and mem_init() later marks the such used pages as reserved.
+ *    Since each TT-Ram chunk is at least 4 MB in size, I hope there
+ *    won't be an overrun of the ST-Ram region by normal kernel data
+ *    space.
+ *
+ * For that, ST-Ram may only be allocated while kernel initialization
+ * is going on, or exactly: before mem_init() is called. There is also
+ * no provision now for freeing ST-Ram buffers. It seems that isn't
+ * really needed.
+ *
+ */
+
+/*
+ * New Nov 1997: Use ST-RAM as swap space!
+ *
+ * In the past, there were often problems with modules that require ST-RAM
+ * buffers. Such drivers have to use __get_dma_pages(), which unfortunately
+ * often isn't very successful in allocating more than 1 page :-( [1] The net
+ * result was that most of the time you couldn't insmod such modules (ataflop,
+ * ACSI, SCSI on Falcon, Atari internal framebuffer, not to speak of acsi_slm,
+ * which needs a 1 MB buffer... :-).
+ *
+ * To overcome this limitation, ST-RAM can now be turned into a very
+ * high-speed swap space. If a request for an ST-RAM buffer comes, the kernel
+ * now tries to unswap some pages on that swap device to make some free (and
+ * contiguous) space. This works much better in comparison to
+ * __get_dma_pages(), since used swap pages can be selectively freed by either
+ * moving them to somewhere else in swap space, or by reading them back into
+ * system memory. Ok, there operation of unswapping isn't really cheap (for
+ * each page, one has to go through the page tables of all processes), but it
+ * doesn't happen that often (only when allocation ST-RAM, i.e. when loading a
+ * module that needs ST-RAM). But it at least makes it possible to load such
+ * modules!
+ *
+ * It could also be that overall system performance increases a bit due to
+ * ST-RAM swapping, since slow ST-RAM isn't used anymore for holding data or
+ * executing code in. It's then just a (very fast, compared to disk) back
+ * storage for not-so-often needed data. (But this effect must be compared
+ * with the loss of total memory...) Don't know if the effect is already
+ * visible on a TT, where the speed difference between ST- and TT-RAM isn't
+ * that dramatic, but it should on machines where TT-RAM is really much faster
+ * (e.g. Afterburner).
+ *
+ *   [1]: __get_free_pages() does a fine job if you only want one page, but if
+ * you want more (contiguous) pages, it can give you such a block only if
+ * there's already a free one. The algorithm can't try to free buffers or swap
+ * out something in order to make more free space, since all that page-freeing
+ * mechanisms work "target-less", i.e. they just free something, but not in a
+ * specific place. I.e., __get_free_pages() can't do anything to free
+ * *adjacent* pages :-( This situation becomes even worse for DMA memory,
+ * since the freeing algorithms are also blind to DMA capability of pages.

+|
+|       bindec
+|
+|       Description:
+|               Converts an input in extended precision format
+|               to bcd format.
+|
+|       Input:
+|               a0 points to the input extended precision value
+|               value in memory; d0 contains the k-factor sign-extended
+|               to 32-bits.  The input may be either normalized,
+|               unnormalized, or denormalized.
+|
+|       Output: result in the FP_SCR1 space on the stack.
+|
+|       Saves and Modifies: D2-D7,A2,FP2
+|
+|       Algorithm:
+|
+|       A1.     Set RM and size ext;  Set SIGMA = sign of input.
+|               The k-factor is saved for use in d7. Clear the
+|               BINDEC_FLG for separating normalized/denormalized
+|               input.  If input is unnormalized or denormalized,
+|               normalize it.
+|
+|       A2.     Set X = abs(input).
+|
+|       A3.     Compute ILOG.
+|               ILOG is the log base 10 of the input value.  It is
+|               approximated by adding e + 0.f when the original
+|               value is viewed as 2^^e * 1.f in extended precision.
+|               This value is stored in d6.
+|
+|       A4.     Clr INEX bit.
+|               The operation in A3 above may have set INEX2.
+|
+|       A5.     Set ICTR = 0;
+|               ICTR is a flag used in A13.  It must be set before the
+|               loop entry A6.
+|
+|       A6.     Calculate LEN.
+|               LEN is the number of digits to be displayed.  The
+|               k-factor can dictate either the total number of digits,
+|               if it is a positive number, or the number of digits
+|               after the decimal point which are to be included as
+|               significant.  See the 68882 manual for examples.
+|               If LEN is computed to be greater than 17, set OPERR in
+|               USER_FPSR.  LEN is stored in d4.
+|
+|       A7.     Calculate SCALE.
+|               SCALE is equal to 10^ISCALE, where ISCALE is the number
+|               of decimal places needed to insure LEN integer digits
+|               in the output before conversion to bcd. LAMBDA is the
+|               sign of ISCALE, used in A9. Fp1 contains
+|               10^^(abs(ISCALE)) using a rounding mode which is a
+|               function of the original rounding mode and the signs
+|               of ISCALE and X.  A table is given in the code.
+|
+|       A8.     Clr INEX; Force RZ.
+|               The operation in A3 above may have set INEX2.
+|               RZ mode is forced for the scaling operation to insure
+|               only one rounding error.  The grs bits are collected in
+|               the INEX flag for use in A10.
+|
+|       A9.     Scale X -> Y.
+|               The mantissa is scaled to the desired number of
+|               significant digits.  The excess digits are collected
+|               in INEX2.
+|
+|       A10.    Or in INEX.
+|               If INEX is set, round error occurred.  This is
+|               compensated for by 'or-ing' in the INEX2 flag to
+|               the lsb of Y.
+|
+|       A11.    Restore original FPCR; set size ext.
+|               Perform FINT operation in the user's rounding mode.
+|               Keep the size to extended.
+|
+|       A12.    Calculate YINT = FINT(Y) according to user's rounding
+|               mode.  The FPSP routine sintd0 is used.  The output
+|               is in fp0.
+|
+|       A13.    Check for LEN digits.
+|               If the int operation results in more than LEN digits,
+|               or less than LEN -1 digits, adjust ILOG and repeat from
+|               A6.  This test occurs only on the first pass.  If the
+|               result is exactly 10^LEN, decrement ILOG and divide
+|               the mantissa by 10.
+|
+|       A14.    Convert the mantissa to bcd.
+|               The binstr routine is used to convert the LEN digit
+|               mantissa to bcd in memory.  The input to binstr is
+|               to be a fraction; i.e. (mantissa)/10^LEN and adjusted
+|               such that the decimal point is to the left of bit 63.
+|               The bcd digits are stored in the correct position in
+|               the final string area in memory.
+|
+|       A15.    Convert the exponent to bcd.
+|               As in A14 above, the exp is converted to bcd and the
+|               digits are stored in the final string.
+|               Test the length of the final exponent string.  If the
+|               length is 4, set operr.
+|
+|       A16.    Write sign bits to final string.
+|
+|       Implementation Notes:
+|
+|       The registers are used as follows:
+|
+|               d0: scratch; LEN input to binstr
+|               d1: scratch
+|               d2: upper 32-bits of mantissa for binstr
+|               d3: scratch;lower 32-bits of mantissa for binstr
+|               d4: LEN
+|               d5: LAMBDA/ICTR
+|               d6: ILOG

+|     of decimal places needed to insure LEN integer digits
+|     in the output before conversion to bcd. LAMBDA is the sign
+|     of ISCALE, used in A9.  Fp1 contains 10^^(abs(ISCALE)) using
+|     the rounding mode as given in the following table (see
+|     Coonen, p. 7.23 as ref.; however, the SCALE variable is
+|     of opposite sign in bindec.sa from Coonen).

+| A9. Scale X -> Y.
+|     The mantissa is scaled to the desired number of significant
+|     digits.  The excess digits are collected in INEX2. If mul,
+|     Check d2 for excess 10 exponential value.  If not zero,
+|     the iscale value would have caused the pwrten calculation
+|     to overflow.  Only a negative iscale can cause this, so
+|     multiply by 10^(d2), which is now only allowed to be 24,
+|     with a multiply by 10^8 and 10^16, which is exact since

+|
+|
+|       Description: Converts a 64-bit binary integer to bcd.
+|
+|       Input: 64-bit binary integer in d2:d3, desired length (LEN) in
+|          d0, and a  pointer to start in memory for bcd characters
+|          in d0. (This pointer must point to byte 4 of the first
+|          lword of the packed decimal memory string.)
+|
+|       Output: LEN bcd digits representing the 64-bit integer.
+|
+|       Algorithm:
+|               The 64-bit binary is assumed to have a decimal point before
+|               bit 63.  The fraction is multiplied by 10 using a mul by 2
+|               shift and a mul by 8 shift.  The bits shifted out of the
+|               msb form a decimal digit.  This process is iterated until
+|               LEN digits are formed.
+|
+|       A1. Init d7 to 1.  D7 is the byte digit counter, and if 1, the
+|               digit formed will be assumed the least significant.  This is
+|               to force the first byte formed to have a 0 in the upper 4 bits.
+|
+|       A2. Beginning of the loop:
+|               Copy the fraction in d2:d3 to d4:d5.
+|
+|       A3. Multiply the fraction in d2:d3 by 8 using bit-field
+|               extracts and shifts.  The three msbs from d2 will go into
+|               d1.
+|
+|       A4. Multiply the fraction in d4:d5 by 2 using shifts.  The msb
+|               will be collected by the carry.
+|
+|       A5. Add using the carry the 64-bit quantities in d2:d3 and d4:d5
+|               into d2:d3.  D1 will contain the bcd digit formed.
+|
+|       A6. Test d7.  If zero, the digit formed is the ms digit.  If non-
+|               zero, it is the ls digit.  Put the digit in its place in the
+|               upper word of d0.  If it is the ls digit, write the word
+|               from d0 to memory.
+|
+|       A7. Decrement d6 (LEN counter) and repeat the loop until zero.
+|
+|       Implementation Notes:
+|
+|       The registers are used as follows:
+|
+|               d0: LEN counter
+|               d1: temp used to form the digit
+|               d2: upper 32-bits of fraction for mul by 8
+|               d3: lower 32-bits of fraction for mul by 8
+|               d4: upper 32-bits of fraction for mul by 2
+|               d5: lower 32-bits of fraction for mul by 2
+|               d6: temp for bit-field extracts
+|               d7: byte digit formation word;digit count {0,1}
+|               a0: pointer into memory for packed bcd string formation

+|
+|       Description: Converts normalized packed bcd value pointed to by
+|       register A6 to extended-precision value in FP0.
+|
+|       Input: Normalized packed bcd value in ETEMP(a6).
+|
+|       Output: Exact floating-point representation of the packed bcd value.
+|
+|       Saves and Modifies: D2-D5
+|
+|       Speed: The program decbin takes ??? cycles to execute.
+|
+|       Object Size:
+|
+|       External Reference(s): None.
+|
+|       Algorithm:
+|       Expected is a normal bcd (i.e. non-exceptional; all inf, zero,
+|       and NaN operands are dispatched without entering this routine)
+|       value in 68881/882 format at location ETEMP(A6).
+|
+|       A1.     Convert the bcd exponent to binary by successive adds and muls.
+|       Set the sign according to SE. Subtract 16 to compensate
+|       for the mantissa which is to be interpreted as 17 integer
+|       digits, rather than 1 integer and 16 fraction digits.
+|       Note: this operation can never overflow.
+|
+|       A2. Convert the bcd mantissa to binary by successive
+|       adds and muls in FP0. Set the sign according to SM.
+|       The mantissa digits will be converted with the decimal point
+|       assumed following the least-significant digit.
+|       Note: this operation can never overflow.
+|
+|       A3. Count the number of leading/trailing zeros in the
+|       bcd string.  If SE is positive, count the leading zeros;
+|       if negative, count the trailing zeros.  Set the adjusted
+|       exponent equal to the exponent from A1 and the zero count
+|       added if SM = 1 and subtracted if SM = 0.  Scale the
+|       mantissa the equivalent of forcing in the bcd value:
+|
+|       SM = 0  a non-zero digit in the integer position
+|       SM = 1  a non-zero digit in Mant0, lsd of the fraction
+|
+|       this will insure that any value, regardless of its
+|       representation (ex. 0.1E2, 1E1, 10E0, 100E-1), is converted
+|       consistently.
+|
+|       A4. Calculate the factor 10^exp in FP1 using a table of
+|       10^(2^n) values.  To reduce the error in forming factors
+|       greater than 10^27, a directed rounding scheme is used with
+|       tables rounded to RN, RM, and RP, according to the table
+|       in the comments of the pwrten section.
+|
+|       A5. Form the final binary number by scaling the mantissa by
+|       the exponent factor.  This is done by multiplying the
+|       mantissa in FP0 by the factor in FP1 if the adjusted
+|       exponent sign is positive, and dividing FP0 by FP1 if
+|       it is negative.
+|
+|       Clean up and return.  Check if the final mul or div resulted
+|       in an inex2 exception.  If so, set inex1 in the fpsr and
+|       check if the inex1 exception is enabled.  If so, set d7 upper
+|       word to $0100.  This will signal unimp.sa that an enabled inex1
+|       exception occurred.  Unimp will fix the stack.

+
+|
+| Append/strip zeros:
+|
+|  For adjusted exponents which have an absolute value greater than 27*,
+|  this routine calculates the amount needed to normalize the mantissa
+|  for the adjusted exponent.  That number is subtracted from the exp
+|  if the exp was positive, and added if it was negative.  The purpose
+|  of this is to reduce the value of the exponent and the possibility
+|  of error in calculation of pwrten.
+|
+|  1. Branch on the sign of the adjusted exponent.
+|  2p.(positive exp)
+|   2. Check M16 and the digits in lwords 2 and 3 in descending order.
+|   3. Add one for each zero encountered until a non-zero digit.
+|   4. Subtract the count from the exp.
+|   5. Check if the exp has crossed zero in #3 above; make the exp abs
+|          and set SE.
+|       6. Multiply the mantissa by 10**count.
+|  2n.(negative exp)
+|   2. Check the digits in lwords 3 and 2 in descending order.
+|   3. Add one for each zero encountered until a non-zero digit.
+|   4. Add the count to the exp.
+|   5. Check if the exp has crossed zero in #3 above; clear SE.
+|   6. Divide the mantissa by 10**count.
+|
+|  *Why 27?  If the adjusted exponent is within -28 < expA < 28, than
+|   any adjustment due to append/strip zeros will drive the resultant
+|   exponent towards zero.  Since all pwrten constants with a power
+|   of 27 or less are exact, there is no need to use this routine to
+|   attempt to lessen the resultant exponent.
+|
+| Register usage:
+|
+|  ap_st_z:
+|       (*)  d0: temp digit storage

+|
+|
+| First check the absolute value of the exponent to see if this
+| routine is necessary.  If so, then check the sign of the exponent
+| and do append (+) or strip (-) zeros accordingly.

+|
+| Do_func performs the unimplemented operation.  The operation
+| to be performed is determined from the lower 7 bits of the
+| extension word (except in the case of fmovecr and fsincos).
+| The opcode and tag bits form an index into a jump table in
+| tbldo.sa.  Cases of zero, infinity and NaN are handled in
+| do_func by forcing the default result.  Normalized and
+| denormalized (there are no unnormalized numbers at this
+| point) are passed onto the emulation code.
+|
+| CMDREG1B and STAG are extracted from the fsave frame
+| and combined to form the table index.  The function called
+| will start with a0 pointing to the ETEMP operand.  Dyadic
+| functions can find FPTEMP at -12(a0).
+|
+| Called functions return their result in fp0.  Sincos returns
+| sin(x) in fp0 and cos(x) in fp1.

+|       fpsp.h --- stack frame offsets during FPSP exception handling
+|
+|       These equates are used to access the exception frame, the fsave
+|       frame and any local variables needed by the FPSP package.
+|
+|       All FPSP handlers begin by executing:

+|               fsave   -(a7)

+|               fmove.l fpsr/fpcr/fpiar,USER_FPSR(a6)
+|
+|       After initialization, the stack looks like this:

+|       Positive offsets from A6 refer to the exception frame.  Negative
+|       offsets refer to the Local Variable area and the fsave area.
+|       The fsave frame is also accessible from the top via A7.
+|
+|       On exit, the handlers execute:
+|
+|               movem.l USER_DA(a6),d0-d1/a0-a1
+|               fmovem.x USER_FP0(a6),fp0-fp3
+|               fmove.l USER_FPSR(a6),fpsr/fpcr/fpiar
+|               frestore (a7)+
+|               unlk    a6
+|
+|       and then either "bra fpsp_done" if the exception was completely
+|       handled by the package, or "bra real_xxxx" which is an external
+|       label to a routine that will process a real exception of the
+|       type that was generated.  Some handlers may omit the "frestore"
+|       if the FPU state after the exception is idle.
+|
+|       Sometimes the exception handler will transform the fsave area
+|       because it needs to report an exception back to the user.  This
+|       can happen if the package is entered for an unimplemented float
+|       instruction that generates (say) an underflow.  Alternatively,
+|       a second fsave frame can be pushed onto the stack and the
+|       handler exit code will reload the new frame and discard the old.
+|
+|       The registers d0, d1, a0, a1 and fp0-fp3 are always saved and
+|       restored from the "local variable" area and can be used as
+|       temporaries.  If a routine needs to change any
+|       of these registers, it should modify the saved copy and let
+|       the handler exit code restore the value.

+|       gen_except --- FPSP routine to detect reportable exceptions
+|
+|       This routine compares the exception enable byte of the
+|       user_fpcr on the stack with the exception status byte
+|       of the user_fpsr.
+|
+|       Any routine which may report an exceptions must load
+|       the stack frame in memory with the exceptional operand(s).
+|
+|       Priority for exceptions is:
+|
+|       Highest:        bsun
+|                       snan
+|                       operr
+|                       ovfl
+|                       unfl
+|                       dz
+|                       inex2
+|       Lowest:         inex1
+|
+|       Note: The IEEE standard specifies that inex2 is to be
+|       reported if ovfl occurs and the ovfl enable bit is not
+|       set but the inex2 enable bit is.

+|
+|  Description: This routine is called by the unsupported format/data
+| type exception handler ('unsupp' - vector 55) and the unimplemented
+| instruction exception handler ('unimp' - vector 11).  'get_op'
+| determines the opclass (0, 2, or 3) and branches to the
+| opclass handler routine.  See 68881/2 User's Manual table 4-11
+| for a description of the opclasses.
+|
+| For UNSUPPORTED data/format (exception vector 55) and for
+| UNIMPLEMENTED instructions (exception vector 11) the following
+| applies:
+|
+| - For unnormalized numbers (opclass 0, 2, or 3) the
+| number(s) is normalized and the operand type tag is updated.
+|
+| - For a packed number (opclass 2) the number is unpacked and the
+| operand type tag is updated.
+|
+| - For denormalized numbers (opclass 0 or 2) the number(s) is not
+| changed but passed to the next module.  The next module for
+| unimp is do_func, the next module for unsupp is res_func.
+|
+| For UNSUPPORTED data/format (exception vector 55) only the
+| following applies:
+|
+| - If there is a move out with a packed number (opclass 3) the
+| number is packed and written to user memory.  For the other
+| opclasses the number(s) are written back to the fsave stack
+| and the instruction is then restored back into the '040.  The
+| '040 is then able to complete the instruction.
+|
+| For example:
+| fadd.x fpm,fpn where the fpm contains an unnormalized number.
+| The '040 takes an unsupported data trap and gets to this
+| routine.  The number is normalized, put back on the stack and
+| then an frestore is done to restore the instruction back into
+| the '040.  The '040 then re-executes the fadd.x fpm,fpn with
+| a normalized number in the source and the instruction is
+| successful.
+|
+| Next consider if in the process of normalizing the un-
+| normalized number it becomes a denormalized number.  The
+| routine which converts the unnorm to a norm (called mk_norm)
+| detects this and tags the number as a denorm.  The routine
+| res_func sees the denorm tag and converts the denorm to a
+| norm.  The instruction is then restored back into the '040
+| which re_executes the instruction.

+| This file contains routines to force exception status in the
+| fpu for exceptional cases detected or reported within the
+| transcendental functions.  Typically, the t_xx routine will
+| set the appropriate bits in the USER_FPSR word on the stack.
+| The bits are tested in gen_except.sa to determine if an exceptional
+| situation needs to be created on return from the FPSP.

+| This code checks for 16-bit overflow conditions on dyadic
+| operations which are not restorable into the floating-point
+| unit and must be completed in software.  Basically, this
+| condition exists with a very large norm and a denorm.  One
+| of the operands must be denormalized to enter this code.
+|
+| Flags used:
+|       DY_MO_FLG contains 0 for monadic op, $ff for dyadic
+|       DNRM_FLG contains $00 for neither op denormalized
+|                         $0f for the destination op denormalized
+|                         $f0 for the source op denormalized
+|                         $ff for both ops denormalized
+|
+| The wrap-around condition occurs for add, sub, div, and cmp
+| when
+|
+|       abs(dest_exp - src_exp) >= $8000
+|
+| and for mul when
+|
+|       (dest_exp + src_exp) < $0
+|
+| we must process the operation here if this case is true.
+|
+| The rts following the frcfpn routine is the exit from res_func
+| for this condition.  The restore flag (RES_FLG) is left clear.
+| No frestore is done unless an exception is to be reported.
+|
+| For fadd:
+|       if(sign_of(dest) != sign_of(src))
+|               replace exponent of src with $3fff (keep sign)
+|               use fpu to perform dest+new_src (user's rmode and X)
+|               clr sticky
+|       else
+|               set sticky
+|       call round with user's precision and mode
+|       move result to fpn and wbtemp
+|
+| For fsub:
+|       if(sign_of(dest) == sign_of(src))
+|               replace exponent of src with $3fff (keep sign)
+|               use fpu to perform dest+new_src (user's rmode and X)

+|
+|       a0 points to the input operand in the internal extended format
+|       d1(high word) contains rounding precision:
+|               ext = $0000xxxx
+|               sgl = $0001xxxx
+|               dbl = $0002xxxx

+|               RN  = $xxxx0000
+|               RZ  = $xxxx0001
+|               RM  = $xxxx0010
+|               RP  = $xxxx0011
+|       d0{31:29} contains the g,r,s bits (extended)
+|
+|       On return the value pointed to by a0 is correctly rounded,
+|       a0 is preserved and the g-r-s bits in d0 are cleared.

+|       sacos.sa 3.3 12/19/90
+|
+|       Description: The entry point sAcos computes the inverse cosine of
+|               an input argument; sAcosd does the same except for denormalized
+|               input.
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The value arccos(X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 3 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program sCOS takes approximately 310 cycles.
+|
+|       Algorithm:
+|
+|       ACOS
+|       1. If |X| >= 1, go to 3.
+|
+|       2. (|X| < 1) Calculate acos(X) by
+|               z := (1-X) / (1+X)
+|               acos(X) = 2 * atan( sqrt(z) ).
+|               Exit.
+|
+|       3. If |X| > 1, go to 5.
+|
+|       4. (|X| = 1) If X > 0, return 0. Otherwise, return Pi. Exit.
+|
+|       5. (|X| > 1) Generate an invalid operation by 0 * infinity.
+|               Exit.

+|
+|       The entry point satan computes the arctangent of an
+|       input value. satand does the same except the input value is a
+|       denormalized number.
+|
+|       Input: Double-extended value in memory location pointed to by address
+|               register a0.
+|
+|       Output: Arctan(X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 2 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program satan takes approximately 160 cycles for input
+|               argument X such that 1/16 < |X| < 16. For the other arguments,
+|               the program will run no worse than 10% slower.
+|
+|       Algorithm:
+|       Step 1. If |X| >= 16 or |X| < 1/16, go to Step 5.
+|
+|       Step 2. Let X = sgn * 2**k * 1.xxxxxxxx...x. Note that k = -4, -3,..., or 3.
+|               Define F = sgn * 2**k * 1.xxxx1, i.e. the first 5 significant bits
+|               of X with a bit-1 attached at the 6-th bit position. Define u
+|               to be u = (X-F) / (1 + X*F).
+|
+|       Step 3. Approximate arctan(u) by a polynomial poly.
+|
+|       Step 4. Return arctan(F) + poly, arctan(F) is fetched from a table of values
+|               calculated beforehand. Exit.
+|
+|       Step 5. If |X| >= 16, go to Step 7.
+|
+|       Step 6. Approximate arctan(X) by an odd polynomial in X. Exit.
+|
+|       Step 7. Define X' = -1/X. Approximate arctan(X') by an odd polynomial in X'.
+|               Arctan(X) = sign(X)*Pi/2 + arctan(X'). Exit.

+|--ATAN(U) IS A VERY SHORT POLYNOMIAL AND THE INDEXING TO
+|--FETCH F AND SAVING OF REGISTERS CAN BE ALL HIDED UNDER THE
+|--DIVIDE. IN THE END THIS METHOD IS MUCH FASTER THAN A TRADITIONAL
+|--ONE. NOTE ALSO THAT THE TRADITIONAL SCHEME THAT APPROXIMATE
+|--ATAN(X) DIRECTLY WILL NEED TO USE A RATIONAL APPROXIMATION

+|       satanh.sa 3.3 12/19/90
+|
+|       The entry point satanh computes the inverse
+|       hyperbolic tangent of
+|       an input argument; satanhd does the same except for denormalized
+|       input.
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The value arctanh(X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 3 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program satanh takes approximately 270 cycles.
+|
+|       Algorithm:
+|
+|       ATANH
+|       1. If |X| >= 1, go to 3.
+|
+|       2. (|X| < 1) Calculate atanh(X) by
+|               sgn := sign(X)
+|               y := |X|
+|               z := 2y/(1-y)
+|               atanh(X) := sgn * (1/2) * logp1(z)
+|               Exit.
+|
+|       3. If |X| > 1, go to 5.
+|
+|       4. (|X| = 1) Generate infinity with an appropriate sign and
+|               divide-by-zero by
+|               sgn := sign(X)
+|               atan(X) := sgn / (+0).
+|               Exit.
+|
+|       5. (|X| > 1) Generate an invalid operation by 0 * infinity.
+|               Exit.

+|
+|       The entry point sCosh computes the hyperbolic cosine of
+|       an input argument; sCoshd does the same except for denormalized
+|       input.
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The value cosh(X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 3 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program sCOSH takes approximately 250 cycles.
+|
+|       Algorithm:
+|
+|       COSH
+|       1. If |X| > 16380 log2, go to 3.
+|
+|       2. (|X| <= 16380 log2) Cosh(X) is obtained by the formulae
+|               y = |X|, z = exp(Y), and
+|               cosh(X) = (1/2)*( z + 1/z ).
+|               Exit.
+|
+|       3. (|X| > 16380 log2). If |X| > 16480 log2, go to 5.
+|
+|       4. (16380 log2 < |X| <= 16480 log2)
+|               cosh(X) = sign(X) * exp(|X|)/2.
+|               However, invoking exp(|X|) may cause premature overflow.
+|               Thus, we calculate sinh(X) as follows:
+|               Y       := |X|
+|               Fact    :=      2**(16380)
+|               Y'      := Y - 16381 log2
+|               cosh(X) := Fact * exp(Y').
+|               Exit.
+|
+|       5. (|X| > 16480 log2) sinh(X) must overflow. Return
+|               Huge*Huge to generate overflow and an infinity with
+|               the appropriate sign. Huge is the largest finite number in
+|               extended format. Exit.

+|       setox.sa 3.1 12/10/90
+|
+|       The entry point setox computes the exponential of a value.
+|       setoxd does the same except the input value is a denormalized
+|       number. setoxm1 computes exp(X)-1, and setoxm1d computes
+|       exp(X)-1 for denormalized X.
+|
+|       INPUT
+|       -----
+|       Double-extended value in memory location pointed to by address
+|       register a0.
+|
+|       OUTPUT
+|       ------
+|       exp(X) or exp(X)-1 returned in floating-point register fp0.
+|
+|       ACCURACY and MONOTONICITY
+|       -------------------------
+|       The returned result is within 0.85 ulps in 64 significant bit, i.e.
+|       within 0.5001 ulp to 53 bits if the result is subsequently rounded
+|       to double precision. The result is provably monotonic in double
+|       precision.
+|
+|       SPEED
+|       -----
+|       Two timings are measured, both in the copy-back mode. The
+|       first one is measured when the function is invoked the first time
+|       (so the instructions and data are not in cache), and the
+|       second one is measured when the function is reinvoked at the same
+|       input argument.
+|
+|       The program setox takes approximately 210/190 cycles for input
+|       argument X whose magnitude is less than 16380 log2, which
+|       is the usual situation. For the less common arguments,
+|       depending on their values, the program may run faster or slower --
+|       but no worse than 10% slower even in the extreme cases.
+|
+|       The program setoxm1 takes approximately ???/??? cycles for input
+|       argument X, 0.25 <= |X| < 70log2. For |X| < 0.25, it takes
+|       approximately ???/??? cycles. For the less common arguments,
+|       depending on their values, the program may run faster or slower --
+|       but no worse than 10% slower even in the extreme cases.
+|
+|       ALGORITHM and IMPLEMENTATION NOTES
+|       ----------------------------------
+|
+|       setoxd
+|       ------
+|       Step 1. Set ans := 1.0
+|
+|       Step 2. Return  ans := ans + sign(X)*2^(-126). Exit.
+|       Notes:  This will always generate one exception -- inexact.
+|
+|
+|       setox
+|       -----
+|
+|       Step 1. Filter out extreme cases of input argument.
+|               1.1     If |X| >= 2^(-65), go to Step 1.3.
+|               1.2     Go to Step 7.
+|               1.3     If |X| < 16380 log(2), go to Step 2.
+|               1.4     Go to Step 8.
+|       Notes:  The usual case should take the branches 1.1 -> 1.3 -> 2.
+|                To avoid the use of floating-point comparisons, a
+|                compact representation of |X| is used. This format is a
+|                32-bit integer, the upper (more significant) 16 bits are
+|                the sign and biased exponent field of |X|; the lower 16
+|                bits are the 16 most significant fraction (including the
+|                explicit bit) bits of |X|. Consequently, the comparisons
+|                in Steps 1.1 and 1.3 can be performed by integer comparison.
+|                Note also that the constant 16380 log(2) used in Step 1.3
+|                is also in the compact form. Thus taking the branch
+|                to Step 2 guarantees |X| < 16380 log(2). There is no harm
+|                to have a small number of cases where |X| is less than,
+|                but close to, 16380 log(2) and the branch to Step 9 is
+|                taken.
+|
+|       Step 2. Calculate N = round-to-nearest-int( X * 64/log2 ).
+|               2.1     Set AdjFlag := 0 (indicates the branch 1.3 -> 2 was taken)
+|               2.2     N := round-to-nearest-integer( X * 64/log2 ).
+|               2.3     Calculate       J = N mod 64; so J = 0,1,2,..., or 63.
+|               2.4     Calculate       M = (N - J)/64; so N = 64M + J.
+|               2.5     Calculate the address of the stored value of 2^(J/64).
+|               2.6     Create the value Scale = 2^M.
+|       Notes:  The calculation in 2.2 is really performed by
+|
+|                       Z := X * constant
+|                       N := round-to-nearest-integer(Z)
+|
+|                where
+|
+|                       constant := single-precision( 64/log 2 ).
+|
+|                Using a single-precision constant avoids memory access.
+|                Another effect of using a single-precision "constant" is
+|                that the calculated value Z is
+|
+|                       Z = X*(64/log2)*(1+eps), |eps| <= 2^(-24).
+|
+|                This error has to be considered later in Steps 3 and 4.
+|
+|       Step 3. Calculate X - N*log2/64.
+|               3.1     R := X + N*L1, where L1 := single-precision(-log2/64).
+|               3.2     R := R + N*L2, L2 := extended-precision(-log2/64 - L1).
+|       Notes:  a) The way L1 and L2 are chosen ensures L1+L2 approximate
+|                the value      -log2/64        to 88 bits of accuracy.
+|                b) N*L1 is exact because N is no longer than 22 bits and
+|                L1 is no longer than 24 bits.
+|                c) The calculation X+N*L1 is also exact due to cancellation.
+|                Thus, R is practically X+N(L1+L2) to full 64 bits.
+|                d) It is important to estimate how large can |R| be after
+|                Step 3.2.
+|
+|                       N = rnd-to-int( X*64/log2 (1+eps) ), |eps|<=2^(-24)
+|                       X*64/log2 (1+eps)       =       N + f,  |f| <= 0.5
+|                       X*64/log2 - N   =       f - eps*X 64/log2
+|                       X - N*log2/64   =       f*log2/64 - eps*X
+|
+|
+|                Now |X| <= 16446 log2, thus
+|
+|                       |X - N*log2/64| <= (0.5 + 16446/2^(18))*log2/64
+|                                       <= 0.57 log2/64.
+|                This bound will be used in Step 4.
+|
+|       Step 4. Approximate exp(R)-1 by a polynomial
+|                       p = R + R*R*(A1 + R*(A2 + R*(A3 + R*(A4 + R*A5))))
+|       Notes:  a) In order to reduce memory access, the coefficients are
+|                made as "short" as possible: A1 (which is 1/2), A4 and A5
+|                are single precision; A2 and A3 are double precision.
+|                b) Even with the restrictions above,
+|                       |p - (exp(R)-1)| < 2^(-68.8) for all |R| <= 0.0062.
+|                Note that 0.0062 is slightly bigger than 0.57 log2/64.
+|                c) To fully utilize the pipeline, p is separated into
+|                two independent pieces of roughly equal complexities
+|                       p = [ R + R*S*(A2 + S*A4) ]     +
+|                               [ S*(A1 + S*(A3 + S*A5)) ]
+|                where S = R*R.
+|
+|       Step 5. Compute 2^(J/64)*exp(R) = 2^(J/64)*(1+p) by
+|                               ans := T + ( T*p + t)
+|                where T and t are the stored values for 2^(J/64).
+|       Notes:  2^(J/64) is stored as T and t where T+t approximates
+|                2^(J/64) to roughly 85 bits; T is in extended precision
+|                and t is in single precision. Note also that T is rounded
+|                to 62 bits so that the last two bits of T are zero. The
+|                reason for such a special form is that T-1, T-2, and T-8
+|                will all be exact --- a property that will give much
+|                more accurate computation of the function EXPM1.
+|
+|       Step 6. Reconstruction of exp(X)
+|                       exp(X) = 2^M * 2^(J/64) * exp(R).
+|               6.1     If AdjFlag = 0, go to 6.3
+|               6.2     ans := ans * AdjScale
+|               6.3     Restore the user FPCR
+|               6.4     Return ans := ans * Scale. Exit.
+|       Notes:  If AdjFlag = 0, we have X = Mlog2 + Jlog2/64 + R,
+|                |M| <= 16380, and Scale = 2^M. Moreover, exp(X) will
+|                neither overflow nor underflow. If AdjFlag = 1, that
+|                means that
+|                       X = (M1+M)log2 + Jlog2/64 + R, |M1+M| >= 16380.
+|                Hence, exp(X) may overflow or underflow or neither.
+|                When that is the case, AdjScale = 2^(M1) where M1 is
+|                approximately M. Thus 6.2 will never cause over/underflow.
+|                Possible exception in 6.4 is overflow or underflow.
+|                The inexact exception is not generated in 6.4. Although
+|                one can argue that the inexact flag should always be
+|                raised, to simulate that exception cost to much than the
+|                flag is worth in practical uses.
+|
+|       Step 7. Return 1 + X.
+|               7.1     ans := X
+|               7.2     Restore user FPCR.
+|               7.3     Return ans := 1 + ans. Exit
+|       Notes:  For non-zero X, the inexact exception will always be
+|                raised by 7.3. That is the only exception raised by 7.3.
+|                Note also that we use the FMOVEM instruction to move X
+|                in Step 7.1 to avoid unnecessary trapping. (Although
+|                the FMOVEM may not seem relevant since X is normalized,
+|                the precaution will be useful in the library version of
+|                this code where the separate entry for denormalized inputs
+|                will be done away with.)
+|
+|       Step 8. Handle exp(X) where |X| >= 16380log2.
+|               8.1     If |X| > 16480 log2, go to Step 9.
+|               (mimic 2.2 - 2.6)
+|               8.2     N := round-to-integer( X * 64/log2 )
+|               8.3     Calculate J = N mod 64, J = 0,1,...,63
+|               8.4     K := (N-J)/64, M1 := truncate(K/2), M = K-M1, AdjFlag := 1.
+|               8.5     Calculate the address of the stored value 2^(J/64).
+|               8.6     Create the values Scale = 2^M, AdjScale = 2^M1.
+|               8.7     Go to Step 3.
+|       Notes:  Refer to notes for 2.2 - 2.6.
+|
+|       Step 9. Handle exp(X), |X| > 16480 log2.
+|               9.1     If X < 0, go to 9.3
+|               9.2     ans := Huge, go to 9.4
+|               9.3     ans := Tiny.
+|               9.4     Restore user FPCR.
+|               9.5     Return ans := ans * ans. Exit.
+|       Notes:  Exp(X) will surely overflow or underflow, depending on
+|                X's sign. "Huge" and "Tiny" are respectively large/tiny
+|                extended-precision numbers whose square over/underflow
+|                with an inexact result. Thus, 9.5 always raises the
+|                inexact together with either overflow or underflow.

+|       Step 1. Set ans := 0
+|
+|       Step 2. Return  ans := X + ans. Exit.
+|       Notes:  This will return X with the appropriate rounding
+|                precision prescribed by the user FPCR.
+|
+|       setoxm1
+|       -------
+|
+|       Step 1. Check |X|
+|               1.1     If |X| >= 1/4, go to Step 1.3.
+|               1.2     Go to Step 7.
+|               1.3     If |X| < 70 log(2), go to Step 2.
+|               1.4     Go to Step 10.
+|       Notes:  The usual case should take the branches 1.1 -> 1.3 -> 2.
+|                However, it is conceivable |X| can be small very often
+|                because EXPM1 is intended to evaluate exp(X)-1 accurately
+|                when |X| is small. For further details on the comparisons,
+|                see the notes on Step 1 of setox.
+|
+|       Step 2. Calculate N = round-to-nearest-int( X * 64/log2 ).
+|               2.1     N := round-to-nearest-integer( X * 64/log2 ).
+|               2.2     Calculate       J = N mod 64; so J = 0,1,2,..., or 63.
+|               2.3     Calculate       M = (N - J)/64; so N = 64M + J.
+|               2.4     Calculate the address of the stored value of 2^(J/64).
+|               2.5     Create the values Sc = 2^M and OnebySc := -2^(-M).
+|       Notes:  See the notes on Step 2 of setox.
+|
+|       Step 3. Calculate X - N*log2/64.
+|               3.1     R := X + N*L1, where L1 := single-precision(-log2/64).
+|               3.2     R := R + N*L2, L2 := extended-precision(-log2/64 - L1).
+|       Notes:  Applying the analysis of Step 3 of setox in this case
+|                shows that |R| <= 0.0055 (note that |X| <= 70 log2 in
+|                this case).
+|
+|       Step 4. Approximate exp(R)-1 by a polynomial
+|                       p = R+R*R*(A1+R*(A2+R*(A3+R*(A4+R*(A5+R*A6)))))
+|       Notes:  a) In order to reduce memory access, the coefficients are
+|                made as "short" as possible: A1 (which is 1/2), A5 and A6
+|                are single precision; A2, A3 and A4 are double precision.
+|                b) Even with the restriction above,
+|                       |p - (exp(R)-1)| <      |R| * 2^(-72.7)
+|                for all |R| <= 0.0055.
+|                c) To fully utilize the pipeline, p is separated into
+|                two independent pieces of roughly equal complexity
+|                       p = [ R*S*(A2 + S*(A4 + S*A6)) ]        +
+|                               [ R + S*(A1 + S*(A3 + S*A5)) ]
+|                where S = R*R.
+|
+|       Step 5. Compute 2^(J/64)*p by
+|                               p := T*p
+|                where T and t are the stored values for 2^(J/64).
+|       Notes:  2^(J/64) is stored as T and t where T+t approximates
+|                2^(J/64) to roughly 85 bits; T is in extended precision
+|                and t is in single precision. Note also that T is rounded
+|                to 62 bits so that the last two bits of T are zero. The
+|                reason for such a special form is that T-1, T-2, and T-8
+|                will all be exact --- a property that will be exploited
+|                in Step 6 below. The total relative error in p is no
+|                bigger than 2^(-67.7) compared to the final result.
+|
+|       Step 6. Reconstruction of exp(X)-1
+|                       exp(X)-1 = 2^M * ( 2^(J/64) + p - 2^(-M) ).
+|               6.1     If M <= 63, go to Step 6.3.
+|               6.2     ans := T + (p + (t + OnebySc)). Go to 6.6
+|               6.3     If M >= -3, go to 6.5.
+|               6.4     ans := (T + (p + t)) + OnebySc. Go to 6.6
+|               6.5     ans := (T + OnebySc) + (p + t).
+|               6.6     Restore user FPCR.
+|               6.7     Return ans := Sc * ans. Exit.
+|       Notes:  The various arrangements of the expressions give accurate
+|                evaluations.
+|
+|       Step 7. exp(X)-1 for |X| < 1/4.
+|               7.1     If |X| >= 2^(-65), go to Step 9.
+|               7.2     Go to Step 8.
+|
+|       Step 8. Calculate exp(X)-1, |X| < 2^(-65).
+|               8.1     If |X| < 2^(-16312), goto 8.3
+|               8.2     Restore FPCR; return ans := X - 2^(-16382). Exit.
+|               8.3     X := X * 2^(140).
+|               8.4     Restore FPCR; ans := ans - 2^(-16382).
+|                Return ans := ans*2^(140). Exit
+|       Notes:  The idea is to return "X - tiny" under the user
+|                precision and rounding modes. To avoid unnecessary
+|                inefficiency, we stay away from denormalized numbers the
+|                best we can. For |X| >= 2^(-16312), the straightforward
+|                8.2 generates the inexact exception as the case warrants.
+|
+|       Step 9. Calculate exp(X)-1, |X| < 1/4, by a polynomial
+|                       p = X + X*X*(B1 + X*(B2 + ... + X*B12))
+|       Notes:  a) In order to reduce memory access, the coefficients are
+|                made as "short" as possible: B1 (which is 1/2), B9 to B12
+|                are single precision; B3 to B8 are double precision; and
+|                B2 is double extended.
+|                b) Even with the restriction above,
+|                       |p - (exp(X)-1)| < |X| 2^(-70.6)
+|                for all |X| <= 0.251.
+|                Note that 0.251 is slightly bigger than 1/4.
+|                c) To fully preserve accuracy, the polynomial is computed
+|                as     X + ( S*B1 +    Q ) where S = X*X and
+|                       Q       =       X*S*(B2 + X*(B3 + ... + X*B12))
+|                d) To fully utilize the pipeline, Q is separated into
+|                two independent pieces of roughly equal complexity
+|                       Q = [ X*S*(B2 + S*(B4 + ... + S*B12)) ] +
+|                               [ S*S*(B3 + S*(B5 + ... + S*B11)) ]
+|
+|       Step 10.        Calculate exp(X)-1 for |X| >= 70 log 2.
+|               10.1 If X >= 70log2 , exp(X) - 1 = exp(X) for all practical
+|                purposes. Therefore, go to Step 1 of setox.
+|               10.2 If X <= -70log2, exp(X) - 1 = -1 for all practical purposes.
+|                ans := -1
+|                Restore user FPCR
+|                Return ans := ans + 2^(-126). Exit.
+|       Notes:  10.2 will always create an inexact and return -1 + tiny
+|                in the user rounding precision and mode.

+|
+|       Algorithm: (sint and sintrz)
+|
+|       1. If exp(X) >= 63, return X.

+|       skeleton.sa 3.2 4/26/91
+|
+|       This file contains code that is system dependent and will
+|       need to be modified to install the FPSP.
+|
+|       Each entry point for exception 'xxxx' begins with a 'jmp fpsp_xxxx'.
+|       Put any target system specific handling that must be done immediately
+|       before the jump instruction.  If there no handling necessary, then
+|       the 'fpsp_xxxx' handler entry point should be placed in the exception
+|       table so that the 'jmp' can be eliminated. If the FPSP determines that the
+|       exception is one that must be reported then there will be a
+|       return from the package by a 'jmp real_xxxx'.  At that point
+|       the machine state will be identical to the state before
+|       the FPSP was entered.  In particular, whatever condition
+|       that caused the exception will still be pending when the FPSP
+|       package returns.  Thus, there will be system specific code
+|       to handle the exception.
+|
+|       If the exception was completely handled by the package, then
+|       the return will be via a 'jmp fpsp_done'.  Unless there is
+|       OS specific work to be done (such as handling a context switch or
+|       interrupt) the user program can be resumed via 'rte'.
+|
+|       In the following skeleton code, some typical 'real_xxxx' handling
+|       code is shown.  This code may need to be moved to an appropriate
+|       place in the target system, or rewritten.

+|       Inexact exception
+|
+|       All inexact exceptions are real, but the 'real' handler
+|       will probably want to clear the pending exception.
+|       The provided code will clear the E3 exception (if pending),
+|       otherwise clear the E1 exception.  The frestore is not really
+|       necessary for E1 exceptions.
+|
+| Code following the 'inex' label is to handle bug #1232.  In this
+| bug, if an E1 snan, ovfl, or unfl occurred, and the process was
+| swapped out before taking the exception, the exception taken on
+| return was inex, rather than the correct exception.  The snan, ovfl,
+| and unfl exception to be taken must not have been enabled.  The
+| fix is to check for E1, and the existence of one of snan, ovfl,
+| or unfl bits set in the fpsr.  If any of these are set, branch
+| to the appropriate  handler for the exception in the fpsr.  Note
+| that this fix is only for d43b parts, and is skipped if the
+| version number is not $40.

+| The supervisor source address is guaranteed to point into the supervisor

+|       slog2.sa 3.1 12/10/90
+|
+|       The entry point slog10 computes the base-10
+|       logarithm of an input argument X.
+|       slog10d does the same except the input value is a
+|       denormalized number.
+|       sLog2 and sLog2d are the base-2 analogues.
+|
+|       INPUT:  Double-extended value in memory location pointed to
+|               by address register a0.
+|
+|       OUTPUT: log_10(X) or log_2(X) returned in floating-point
+|               register fp0.
+|
+|       ACCURACY and MONOTONICITY: The returned result is within 1.7
+|               ulps in 64 significant bit, i.e. within 0.5003 ulp
+|               to 53 bits if the result is subsequently rounded
+|               to double precision. The result is provably monotonic
+|               in double precision.
+|
+|       SPEED:  Two timings are measured, both in the copy-back mode.
+|               The first one is measured when the function is invoked
+|               the first time (so the instructions and data are not
+|               in cache), and the second one is measured when the
+|               function is reinvoked at the same input argument.
+|
+|       ALGORITHM and IMPLEMENTATION NOTES:

+|                 traps, and precision control = double extended.
+|
+|       Step 1.   If X is not an integer power of two, i.e., X != 2^k,
+|                 go to Step 3.
+|
+|       Step 2.   Return k.

+|       slogn.sa 3.1 12/10/90
+|
+|       slogn computes the natural logarithm of an
+|       input value. slognd does the same except the input value is a
+|       denormalized number. slognp1 computes log(1+X), and slognp1d
+|       computes log(1+X) for denormalized X.
+|
+|       Input: Double-extended value in memory location pointed to by address
+|               register a0.
+|
+|       Output: log(X) or log(1+X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 2 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program slogn takes approximately 190 cycles for input
+|               argument X such that |X-1| >= 1/16, which is the usual
+|               situation. For those arguments, slognp1 takes approximately
+|                210 cycles. For the less common arguments, the program will
+|                run no worse than 10% slower.
+|
+|       Algorithm:
+|       LOGN:
+|       Step 1. If |X-1| < 1/16, approximate log(X) by an odd polynomial in
+|               u, where u = 2(X-1)/(X+1). Otherwise, move on to Step 2.
+|
+|       Step 2. X = 2**k * Y where 1 <= Y < 2. Define F to be the first seven
+|               significant bits of Y plus 2**(-7), i.e. F = 1.xxxxxx1 in base
+|               2 where the six "x" match those of Y. Note that |Y-F| <= 2**(-7).
+|
+|       Step 3. Define u = (Y-F)/F. Approximate log(1+u) by a polynomial in u,
+|               log(1+u) = poly.
+|
+|       Step 4. Reconstruct log(X) = log( 2**k * Y ) = k*log(2) + log(F) + log(1+u)
+|               by k*log(2) + (log(F) + poly). The values of log(F) are calculated
+|               beforehand and stored in the program.
+|
+|       lognp1:
+|       Step 1: If |X| < 1/16, approximate log(1+X) by an odd polynomial in
+|               u where u = 2X/(2+X). Otherwise, move on to Step 2.
+|
+|       Step 2: Let 1+X = 2**k * Y, where 1 <= Y < 2. Define F as done in Step 2
+|               of the algorithm for LOGN and compute log(1+X) as
+|               k*log(2) + log(F) + poly where poly approximates log(1+u),
+|               u = (Y-F)/F.
+|
+|       Implementation Notes:
+|       Note 1. There are 64 different possible values for F, thus 64 log(F)'s
+|               need to be tabulated. Moreover, the values of 1/F are also
+|               tabulated so that the division in (Y-F)/F can be performed by a
+|               multiplication.
+|
+|       Note 2. In Step 2 of lognp1, in order to preserved accuracy, the value
+|               Y-F has to be calculated carefully when 1/2 <= X < 3/2.
+|
+|       Note 3. To fully exploit the pipeline, polynomials are usually separated
+|               into two parts evaluated independently before being added up.

+|      The entry point sMOD computes the floating point MOD of the
+|      input values X and Y. The entry point sREM computes the floating
+|      point (IEEE) REM of the input values X and Y.
+|
+|      INPUT
+|      -----
+|      Double-extended value Y is pointed to by address in register
+|      A0. Double-extended value X is located in -12(A0). The values
+|      of X and Y are both nonzero and finite; although either or both
+|      of them can be denormalized. The special cases of zeros, NaNs,
+|      and infinities are handled elsewhere.
+|
+|      OUTPUT
+|      ------
+|      FREM(X,Y) or FMOD(X,Y), depending on entry point.
+|
+|       ALGORITHM
+|       ---------
+|
+|       Step 1.  Save and strip signs of X and Y: signX := sign(X),
+|                signY := sign(Y), X := |X|, Y := |Y|,
+|                signQ := signX EOR signY. Record whether MOD or REM
+|                is requested.
+|
+|       Step 2.  Set L := expo(X)-expo(Y), k := 0, Q := 0.
+|                If (L < 0) then
+|                   R := X, go to Step 4.
+|                else
+|                   R := 2^(-L)X, j := L.
+|                endif
+|
+|       Step 3.  Perform MOD(X,Y)
+|            3.1 If R = Y, go to Step 9.
+|            3.2 If R > Y, then { R := R - Y, Q := Q + 1}
+|            3.3 If j = 0, go to Step 4.
+|            3.4 k := k + 1, j := j - 1, Q := 2Q, R := 2R. Go to
+|                Step 3.1.
+|
+|       Step 4.  At this point, R = X - QY = MOD(X,Y). Set
+|                Last_Subtract := false (used in Step 7 below). If
+|                MOD is requested, go to Step 6.
+|
+|       Step 5.  R = MOD(X,Y), but REM(X,Y) is requested.
+|            5.1 If R < Y/2, then R = MOD(X,Y) = REM(X,Y). Go to
+|                Step 6.
+|            5.2 If R > Y/2, then { set Last_Subtract := true,
+|                Q := Q + 1, Y := signY*Y }. Go to Step 6.
+|            5.3 This is the tricky case of R = Y/2. If Q is odd,
+|                then { Q := Q + 1, signX := -signX }.
+|
+|       Step 6.  R := signX*R.
+|
+|       Step 7.  If Last_Subtract = true, R := R - Y.
+|
+|       Step 8.  Return signQ, last 7 bits of Q, and R as required.
+|
+|       Step 9.  At this point, R = 2^(-j)*X - Q Y = Y. Thus,
+|                X = 2^(j)*(Q+1)Y. set Q := 2^(j)*(Q+1),
+|                R := 0. Return signQ, last 7 bits of Q, and R.

+|       ssin.sa 3.3 7/29/91
+|
+|       The entry point sSIN computes the sine of an input argument
+|       sCOS computes the cosine, and sSINCOS computes both. The
+|       corresponding entry points with a "d" computes the same
+|       corresponding function values for denormalized inputs.
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The function value sin(X) or cos(X) returned in Fp0 if SIN or
+|               COS is requested. Otherwise, for SINCOS, sin(X) is returned
+|               in Fp0, and cos(X) is returned in Fp1.
+|
+|       Modifies: Fp0 for SIN or COS; both Fp0 and Fp1 for SINCOS.
+|
+|       Accuracy and Monotonicity: The returned result is within 1 ulp in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The programs sSIN and sCOS take approximately 150 cycles for
+|               input argument X such that |X| < 15Pi, which is the usual
+|               situation. The speed for sSINCOS is approximately 190 cycles.
+|
+|       Algorithm:
+|
+|       SIN and COS:
+|       1. If SIN is invoked, set AdjN := 0; otherwise, set AdjN := 1.
+|
+|       2. If |X| >= 15Pi or |X| < 2**(-40), go to 7.
+|
+|       3. Decompose X as X = N(Pi/2) + r where |r| <= Pi/4. Let
+|               k = N mod 4, so in particular, k = 0,1,2,or 3. Overwrite
+|               k by k := k + AdjN.
+|
+|       4. If k is even, go to 6.
+|
+|       5. (k is odd) Set j := (k-1)/2, sgn := (-1)**j. Return sgn*cos(r)
+|               where cos(r) is approximated by an even polynomial in r,
+|               1 + r*r*(B1+s*(B2+ ... + s*B8)),        s = r*r.
+|               Exit.
+|
+|       6. (k is even) Set j := k/2, sgn := (-1)**j. Return sgn*sin(r)
+|               where sin(r) is approximated by an odd polynomial in r
+|               r + r*s*(A1+s*(A2+ ... + s*A7)),        s = r*r.
+|               Exit.
+|
+|       7. If |X| > 1, go to 9.
+|
+|       8. (|X|<2**(-40)) If SIN is invoked, return X; otherwise return 1.
+|
+|       9. Overwrite X by X := X rem 2Pi. Now that |X| <= Pi, go back to 3.
+|
+|       SINCOS:
+|       1. If |X| >= 15Pi or |X| < 2**(-40), go to 6.
+|
+|       2. Decompose X as X = N(Pi/2) + r where |r| <= Pi/4. Let
+|               k = N mod 4, so in particular, k = 0,1,2,or 3.
+|
+|       3. If k is even, go to 5.
+|
+|       4. (k is odd) Set j1 := (k-1)/2, j2 := j1 (EOR) (k mod 2), i.e.
+|               j1 exclusive or with the l.s.b. of k.
+|               sgn1 := (-1)**j1, sgn2 := (-1)**j2.
+|               SIN(X) = sgn1 * cos(r) and COS(X) = sgn2*sin(r) where
+|               sin(r) and cos(r) are computed as odd and even polynomials
+|               in r, respectively. Exit
+|
+|       5. (k is even) Set j1 := k/2, sgn1 := (-1)**j1.
+|               SIN(X) = sgn1 * sin(r) and COS(X) = sgn1*cos(r) where
+|               sin(r) and cos(r) are computed as odd and even polynomials
+|               in r, respectively. Exit
+|
+|       6. If |X| > 1, go to 8.
+|
+|       7. (|X|<2**(-40)) SIN(X) = X and COS(X) = 1. Exit.
+|
+|       8. Overwrite X by X := X rem 2Pi. Now that |X| <= Pi, go back to 2.

+|       ssinh.sa 3.1 12/10/90
+|
+|       The entry point sSinh computes the hyperbolic sine of
+|       an input argument; sSinhd does the same except for denormalized
+|       input.
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The value sinh(X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 3 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program sSINH takes approximately 280 cycles.
+|
+|       Algorithm:
+|
+|       SINH
+|       1. If |X| > 16380 log2, go to 3.
+|
+|       2. (|X| <= 16380 log2) Sinh(X) is obtained by the formulae
+|               y = |X|, sgn = sign(X), and z = expm1(Y),
+|               sinh(X) = sgn*(1/2)*( z + z/(1+z) ).
+|          Exit.
+|
+|       3. If |X| > 16480 log2, go to 5.
+|
+|       4. (16380 log2 < |X| <= 16480 log2)
+|               sinh(X) = sign(X) * exp(|X|)/2.
+|          However, invoking exp(|X|) may cause premature overflow.
+|          Thus, we calculate sinh(X) as follows:
+|             Y       := |X|
+|             sgn     := sign(X)
+|             sgnFact := sgn * 2**(16380)
+|             Y'      := Y - 16381 log2
+|             sinh(X) := sgnFact * exp(Y').
+|          Exit.
+|
+|       5. (|X| > 16480 log2) sinh(X) must overflow. Return
+|          sign(X)*Huge*Huge to generate overflow and an infinity with
+|          the appropriate sign. Huge is the largest finite number in
+|          extended format. Exit.

+|
+|       Algorithm:
+|
+|       1. If |X| >= 15Pi or |X| < 2**(-40), go to 6.
+|
+|       2. Decompose X as X = N(Pi/2) + r where |r| <= Pi/4. Let

+|

+|               Exit.
+|
+|       4. (k is odd) Tan(X) = -cot(r). Since tan(r) is approximated by a
+|               rational function U/V where
+|               U = r + r*s*(P1 + s*(P2 + s*P3)), and

+|
+|       6. If |X| > 1, go to 8.
+|
+|       7. (|X|<2**(-40)) Tan(X) = X. Exit.

+|       stanh.sa 3.1 12/10/90
+|
+|       The entry point sTanh computes the hyperbolic tangent of
+|       an input argument; sTanhd does the same except for denormalized
+|       input.
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The value tanh(X) returned in floating-point register Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 3 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program stanh takes approximately 270 cycles.
+|
+|       Algorithm:
+|
+|       TANH
+|       1. If |X| >= (5/2) log2 or |X| <= 2**(-40), go to 3.
+|
+|       2. (2**(-40) < |X| < (5/2) log2) Calculate tanh(X) by
+|               sgn := sign(X), y := 2|X|, z := expm1(Y), and
+|               tanh(X) = sgn*( z/(2+z) ).
+|               Exit.
+|
+|       3. (|X| <= 2**(-40) or |X| >= (5/2) log2). If |X| < 1,
+|               go to 7.
+|
+|       4. (|X| >= (5/2) log2) If |X| >= 50 log2, go to 6.
+|
+|       5. ((5/2) log2 <= |X| < 50 log2) Calculate tanh(X) by
+|               sgn := sign(X), y := 2|X|, z := exp(Y),
+|               tanh(X) = sgn - [ sgn*2/(1+z) ].
+|               Exit.
+|
+|       6. (|X| >= 50 log2) Tanh(X) = +-1 (round to nearest). Thus, we
+|               calculate Tanh(X) by
+|               sgn := sign(X), Tiny := 2**(-126),
+|               tanh(X) := sgn - sgn*Tiny.
+|               Exit.
+|
+|       7. (|X| < 2**(-40)). Tanh(X) = X.       Exit.

+|       stentox  --- 10**X
+|       stentoxd --- 10**X for denormalized X
+|
+|       Input: Double-extended number X in location pointed to
+|               by address register a0.
+|
+|       Output: The function values are returned in Fp0.
+|
+|       Accuracy and Monotonicity: The returned result is within 2 ulps in
+|               64 significant bit, i.e. within 0.5001 ulp to 53 bits if the
+|               result is subsequently rounded to double precision. The
+|               result is provably monotonic in double precision.
+|
+|       Speed: The program stwotox takes approximately 190 cycles and the
+|               program stentox takes approximately 200 cycles.
+|
+|       Algorithm:
+|
+|       twotox
+|       1. If |X| > 16480, go to ExpBig.
+|
+|       2. If |X| < 2**(-70), go to ExpSm.
+|
+|       3. Decompose X as X = N/64 + r where |r| <= 1/128. Furthermore
+|               decompose N as
+|                N = 64(M + M') + j,  j = 0,1,2,...,63.
+|
+|       4. Overwrite r := r * log2. Then
+|               2**X = 2**(M') * 2**(M) * 2**(j/64) * exp(r).
+|               Go to expr to compute that expression.
+|
+|       tentox
+|       1. If |X| > 16480*log_10(2) (base 10 log of 2), go to ExpBig.
+|
+|       2. If |X| < 2**(-70), go to ExpSm.
+|
+|       3. Set y := X*log_2(10)*64 (base 2 log of 10). Set
+|               N := round-to-int(y). Decompose N as
+|                N = 64(M + M') + j,  j = 0,1,2,...,63.
+|
+|       4. Define r as
+|               r := ((X - N*L1)-N*L2) * L10
+|               where L1, L2 are the leading and trailing parts of log_10(2)/64
+|               and L10 is the natural log of 10. Then
+|               10**X = 2**(M') * 2**(M) * 2**(j/64) * exp(r).
+|               Go to expr to compute that expression.
+|
+|       expr
+|       1. Fetch 2**(j/64) from table as Fact1 and Fact2.
+|
+|       2. Overwrite Fact1 and Fact2 by
+|               Fact1 := 2**(M) * Fact1
+|               Fact2 := 2**(M) * Fact2
+|               Thus Fact1 + Fact2 = 2**(M) * 2**(j/64).
+|
+|       3. Calculate P where 1 + P approximates exp(r):
+|               P = r + r*r*(A1+r*(A2+...+r*A5)).
+|
+|       4. Let AdjFact := 2**(M'). Return
+|               AdjFact * ( Fact1 + ((Fact1*P) + Fact2) ).
+|               Exit.
+|
+|       ExpBig
+|       1. Generate overflow by Huge * Huge if X > 0; otherwise, generate
+|               underflow by Tiny * Tiny.
+|
+|       ExpSm
+|       1. Return 1 + X.

+| Modified:
+|       8/16/90 chinds  The table was constructed to use only one level
+|                       of indirection in do_func for monadic
+|                       functions.  Dyadic functions require two
+|                       levels, and the tables are still contained
+|                       in do_func.  The table is arranged for
+|                       index with a 10-bit index, with the first
+|                       7 bits the opcode, and the remaining 3
+|                       the stag.  For dyadic functions, all
+|                       valid addresses are to the generic entry
+|                       point.

+| Note 1: For trap disabled 040 does the following:
+| If the dest is a fp reg, then an extended precision non_signaling
+| NAN is stored in the dest reg.  If the dest format is b, w, or l and
+| the source op is a NAN, then garbage is stored as the result (actually

+| the dest format is integer (b, w, l) and the operr is caused by
+| integer overflow, or the source op is inf, then the result stored is
+| garbage.
+| There are three cases in which operr is incorrectly signaled on the
+| 040.  This occurs for move_out of format b, w, or l for the largest
+| negative integer (-2^7 for b, -2^15 for w, -2^31 for l).

+|         overflow -> OPERR, the exponent in wbte (and fpte) is:
+|               byte    56 - (62 - exp)
+|               word    48 - (62 - exp)
+|               long    32 - (62 - exp)
+|
+|                       where exp = (true exp) - 1
+|
+|  So, wbtemp and fptemp will contain the following on erroneously
+|         signalled operr:
+|                       fpts = 1
+|                       fpte = $4000  (15 bit externally)
+|               byte    fptm = $ffffffff ffffff80
+|               word    fptm = $ffffffff ffff8000
+|               long    fptm = $ffffffff 80000000
+|
+| Note 2: For trap enabled 040 does the following:
+| If the inst is move_out, then same as Note 1.
+| If the inst is not move_out, the dest is not modified.
+| The exceptional operand is not defined for integer overflow
+| during a move_out.

+|       fpsp_ovfl --- FPSP handler for overflow exception
+|
+|       Overflow occurs when a floating-point intermediate result is
+|       too large to be represented in a floating-point data register,
+|       or when storing to memory, the contents of a floating-point
+|       data register are too large to be represented in the
+|       destination format.
+|
+| Trap disabled results
+|
+| If the instruction is move_out, then garbage is stored in the
+| destination.  If the instruction is not move_out, then the
+| destination is not affected.  For 68881 compatibility, the
+| following values should be stored at the destination, based
+| on the current rounding mode:
+|
+|  RN   Infinity with the sign of the intermediate result.
+|  RZ   Largest magnitude number, with the sign of the
+|       intermediate result.
+|  RM   For pos overflow, the largest pos number. For neg overflow,
+|       -infinity
+|  RP   For pos overflow, +infinity. For neg overflow, the largest
+|       neg number
+|
+| Trap enabled results
+| All trap disabled code applies.  In addition the exceptional
+| operand needs to be made available to the users exception handler
+| with a bias of $6000 subtracted from the exponent.

+| fpsp_snan --- FPSP handler for signalling NAN exception
+|
+| SNAN for float -> integer conversions (integer conversion of
+| an SNAN) is a non-maskable run-time exception.
+|
+| For trap disabled the 040 does the following:
+| If the dest data format is s, d, or x, then the SNAN bit in the NAN
+| is set to one and the resulting non-signaling NAN (truncated if
+| necessary) is transferred to the dest.  If the dest format is b, w,
+| or l, then garbage is written to the dest (actually the upper 32 bits
+| of the mantissa are sent to the integer unit).
+|
+| For trap enabled the 040 does the following:
+| If the inst is move_out, then the results are the same as for trap
+| disabled with the exception posted.  If the instruction is not move_
+| out, the dest. is not modified, and the exception is posted.

+| Trap disabled results
+|       For 881/2 compatibility, sw must denormalize the intermediate
+| result, then store the result.  Denormalization is accomplished
+| by taking the intermediate result (which is always normalized) and
+| shifting the mantissa right while incrementing the exponent until
+| it is equal to the denormalized exponent for the destination
+| format.  After denormalization, the result is rounded to the
+| destination format.
+|
+| Trap enabled results
+|       All trap disabled code applies. In addition the exceptional
+| operand needs to made available to the user with a bias of $6000
+| added to the exponent.

+HP300 notes
+-----------
+
+The Linux/HP web page is at <http://www.tazenda.demon.co.uk/phil/linux-hp/>
+
+Currently only 9000/340 machines have been tested.  Any amount of RAM should
+work now but I've only tried 16MB and 12MB.
+
+The serial console is probably broken at the moment but the Topcat/HIL keyboard
+combination seems to work for me.  Your mileage may vary.
+
+The LANCE driver works after a fashion but only if you reset the chip before
+every packet.  This doesn't make for very speedy operation.

+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+CHANGES SINCE LAST RELEASE:
+---------------------------
+
+1) "movep" emulation where data was being read from memory
+was reading the intermediate bytes. Emulation now only
+reads the required bytes.
+
+2) "flogn", "flog2", and "flog10" of "1" was setting the
+Inexact FPSR bit. Emulation now does not set Inexact for
+this case.
+
+3) For an opclass three FP instruction where the effective addressing
+mode was pre-decrement or post-increment and the address register
+was A0 or A1, the address register was not being updated as a result
+of the operation. This has been corrected.
+
+4) Beta B.2 version had the following erratum:
+
+        Scenario:
+        ---------
+        If {i,d}mem_{read,write}_{byte,word,long}() returns
+        a failing value to the 68060SP, the package ignores
+        this return value and continues with program execution
+        as if it never received a failing value.
+
+        Effect:
+        -------
+        For example, if a user executed "fsin.x ADDR,fp0" where
+        ADDR should cause a "segmentation violation", the memory read
+        requested by the package should return a failing value
+        to the package. Since the package currently ignores this
+        return value, the user program will continue to the
+        next instruction, and the result created in fp0 will be
+        undefined.
+
+        Fix:
+        ----
+        This has been fixed in the current release.
+
+        Notes:
+        ------
+        Upon receiving a non-zero (failing) return value from
+        a {i,d}mem_{read,write}_{byte,word,long}() "call-out",
+        the package creates a 16-byte access error stack frame
+        from the current exception stack frame and exits
+        through the "call-out" _real_access(). This is the process
+        as described in the MC68060 User's Manual.
+
+        For instruction read access errors, the info stacked is:
+                SR      = SR at time of exception
+                PC      = PC of instruction being emulated
+                VOFF    = $4008 (stack frame format type)
+                ADDRESS = PC of instruction being emulated
+                FSLW    = FAULT STATUS LONGWORD
+
+        The valid FSLW bits are:
+                bit 27          = 1     (misaligned bit)
+                bit 24          = 1     (read)
+                bit 23          = 0     (write)
+                bit 22:21       = 10    (SIZE = word)
+                bit 20:19       = 00    (TT)
+                bit 18:16       = x10   (TM; x = 1 for supervisor mode)
+                bit 15          = 1     (IO)
+                bit 0           = 1     (Software Emulation Error)
+
+        all other bits are EQUAL TO ZERO and can be set by the _real_access()
+        "call-out" stub by the user as appropriate. The MC68060 User's Manual
+        stated that ONLY "bit 0" would be set. The 060SP attempts to set a few
+        other bits.
+
+        For data read/write access errors, the info stacked is:
+                SR      = SR at time of exception
+                PC      = PC of instruction being emulated
+                VOFF    = $4008 (stack frame format type)
+                ADDRESS = Address of source or destination operand
+                FSLW    = FAULT STATUS LONGWORD
+
+        The valid FSLW bits are:
+                bit 27          = 0     (misaligned bit)
+                bit 24          = x     (read; 1 if read, 0 if write)
+                bit 23          = x     (write; 1 if write, 0 if read)
+                bit 22:21       = xx    (SIZE; see MC68060 User's Manual)
+                bit 20:19       = 00    (TT)
+                bit 18:16       = x01   (TM; x = 1 for supervisor mode)
+                bit 15          = 0     (IO)
+                bit 0           = 1     (Software Emulation Error)
+
+        all other bits are EQUAL TO ZERO and can be set by the _real_access()
+        "call-out" stub by the user as appropriate. The MC68060 User's Manual

+68060 SOFTWARE PACKAGE (Kernel version) SIMPLE TESTS
+-----------------------------------------------------
+
+The files itest.sa and ftest.sa contain simple tests to check
+the state of the 68060ISP and 68060FPSP once they have been installed.
+
+Release file format:
+--------------------
+The release files itest.sa and ftest.sa are essentially
+hexadecimal images of the actual tests. This format is the
+ONLY format that will be supported. The hex images were created
+by assembling the source code and then converting the resulting
+binary output images into ASCII text files. The hexadecimal
+numbers are listed using the Motorola Assembly syntax assembler
+directive "dc.l" (define constant longword). The files can be
+converted to other assembly syntaxes by using any word processor
+with a global search and replace function.
+
+To assist in assembling and linking these modules with other modules,
+the installer should add symbolic labels to the top of the files.
+This will allow the calling routines to access the entry points
+of these packages.
+
+The source code itest.s and ftest.s have been included but only
+for documentation purposes.
+
+Release file structure:
+-----------------------
+
+(top of module)
+        -----------------
+        |               | - 128 byte-sized section
+   (1)  |   Call-Out    | - 4 bytes per entry (user fills these in)
+        |               |
+        -----------------
+        |               | - 8 bytes per entry
+   (2)  | Entry Point   | - user does "bsr" or "jsr" to this address
+        |               |
+        -----------------
+        |               | - code section
+   (3)  ~               ~
+        |               |
+        -----------------
+(bottom of module)
+
+The first section of this module is the "Call-out" section. This section
+is NOT INCLUDED in {i,f}test.sa (an example "Call-out" section is provided at
+the end of this file). The purpose of this section is to allow the test
+routines to reference external printing functions that must be provided
+by the host operating system. This section MUST be exactly 128 bytes in
+size. There are 32 fields, each 4 bytes in size. Each field corresponds
+to a function required by the test packages (these functions and their
+location are listed in "68060{ISP,FPSP}-TEST call-outs" below). Each field
+entry should contain the address of the corresponding function RELATIVE to
+the starting address of the "call-out" section. The "Call-out" section must
+sit adjacent to the {i,f}test.sa image in memory. Since itest.sa and ftest.sa
+are individual tests, they each require their own "Call-out" sections.
+
+The second section, the "Entry-point" section, is used by external routines
+to access the test routines. Since the {i,f}test.sa hex files contain
+no symbol names, this section contains function entry points that are fixed
+with respect to the top of the package. The currently defined entry-points
+are listed in section "68060{ISP,FPSP}-TEST entry points" below. A calling
+routine would simply execute a "bsr" or "jsr" that jumped to the selected
+function entry-point.
+
+For example, to run the 060ISP test, write a program that includes the
+itest.sa data and execute something similar to:
+
+        bsr     _060ISP_TEST+128+0
+
+(_060ISP_TEST is the starting address of the "Call-out" section; the "Call-out"
+section is 128 bytes long; and the 68060ISP test entry point is located
+0 bytes from the top of the "Entry-point" section.)
+
+The third section is the code section. After entering through an "Entry-point",
+the entry code jumps to the appropriate test code within the code section.
+
+68060ISP-TEST Call-outs:
+------------------------
+0x0: _print_string()
+0x4: _print_number()
+
+68060FPSP-TEST Call-outs:
+-------------------------
+0x0: _print_string()
+0x4: _print_number()
+
+The test packages call _print_string() and _print_number()
+as subroutines and expect the main program to print a string
+or a number to a file or to the screen.
+In "C"-like fashion, the test program calls:
+
+        print_string("Test passed");
+
+                or
+
+        print_number(20);
+
+For _print_string(), the test programs pass a longword address
+of the string on the stack. For _print_number(), the test programs pass
+a longword number to be printed.
+
+For debugging purposes, after the main program performs a "print"
+for a test package, it should flush the output so that it's not
+buffered. In this way, if the test program crashes, at least the previous
+statements printed will be seen.
+
+68060ISP-TEST Entry-points:
+---------------------------
+0x0: integer test
+
+68060FPSP-TEST Entry-points:
+----------------------------
+0x00: main fp test
+0x08: FP unimplemented test
+0x10: FP enabled snan/operr/ovfl/unfl/dz/inex
+
+The floating-point unit test has 3 entry points which will require
+3 different calls to the package if each of the three following tests
+is desired:
+
+main fp test: tests (1) unimp effective address exception
+                    (2) unsupported data type exceptions
+                    (3) non-maskable overflow/underflow exceptions
+
+FP unimplemented: tests FP unimplemented exception. this one is
+                  separate from the previous tests for systems that don't
+                  want FP unimplemented instructions.
+
+FP enabled: tests enabled snan/operr/ovfl/unfl/dz/inex.
+            basically, it enables each of these exceptions and forces
+            each using an implemented FP instruction. this process
+            exercises _fpsp_{snan,operr,ovfl,unfl,dz,inex}() and
+            _real_{snan,operr,ovfl,unfl,dz,inex}(). the test expects
+            _real_XXXX() to do nothing except clear the exception
+            and "rte". if a system's _real_XXXX() handler creates an
+            alternate result, the test will print "failed" but this
+            is acceptable.
+
+Miscellaneous:
+--------------
+Again, itest.sa and ftest.sa are simple tests and do not thoroughly
+test all 68060SP connections. For example, they do not test connections
+to _real_access(), _real_trace(), _real_trap(), etc. because these
+will be system-implemented several different ways and the test packages
+must remain system independent.
+
+Example test package set-up:
+----------------------------
+_print_str:
+        .                       # provided by system
+        rts
+
+_print_num:

+
+68060 FLOATING-POINT SOFTWARE PACKAGE (Library version)
+--------------------------------------------------------
+
+The file fplsp.sa contains the "Library version" of the
+68060SP Floating-Point Software Package. The routines
+included in this module can be used to emulate the
+FP instructions not implemented in 68060 hardware. These
+instructions normally take exception vector #11
+"FP Unimplemented Instruction".
+
+By re-compiling a program that uses these instructions, and
+making subroutine calls in place of the unimplemented
+instructions, a program can avoid the overhead associated
+with taking the exception.
+
+Release file format:
+--------------------
+The file fplsp.sa is essentially a hexadecimal image of the
+release package. This is the ONLY format which will be supported.
+The hex image was created by assembling the source code and
+then converting the resulting binary output image into an
+ASCII text file. The hexadecimal numbers are listed
+using the Motorola Assembly Syntax assembler directive "dc.l"
+(define constant longword). The file can be converted to other
+assembly syntaxes by using any word processor with a global
+search and replace function.
+
+To assist in assembling and linking this module with other modules,
+the installer should add a symbolic label to the top of the file.
+This will allow calling routines to access the entry points
+of this package.
+
+The source code fplsp.s has also been included but only for
+documentation purposes.
+
+Release file structure:
+-----------------------
+The file fplsp.sa contains an "Entry-Point" section and a
+code section. The FPLSP has no "Call-Out" section. The first section
+is the "Entry-Point" section. In order to access a function in the
+package, a program must "bsr" or "jsr" to the location listed
+below in "68060FPLSP entry points" that corresponds to the desired
+function. A branch instruction located at the selected entry point
+within the package will then enter the correct emulation code routine.
+
+The entry point addresses at the beginning of the package will remain
+fixed so that a program calling the routines will not have to be
+re-compiled with every new 68060FPLSP release.
+
+There are 3 entry-points for each instruction type: single precision,
+double precision, and extended precision.
+
+As an example, the "fsin" library instruction can be passed an
+extended precision operand if program executes:
+
+# fsin.x fp0
+
+        fmovm.x &0x01,-(%sp)    # pass operand on stack
+        bsr.l   _060FPLSP_TOP+0x1a8 # branch to fsin routine
+        add.l   &0xc,%sp        # clear operand from stack
+
+Upon return, fp0 holds the correct result. The FPSR is
+set correctly. The FPCR is unchanged. The FPIAR is undefined.
+
+Another example. This time, a dyadic operation:
+
+# frem.s %fp1,%fp0
+
+        fmov.s  %fp1,-(%sp)     # pass src operand
+        fmov.s  %fp0,-(%sp)     # pass dst operand
+        bsr.l   _060FPLSP_TOP+0x168 # branch to frem routine
+        addq.l  &0x8,%sp        # clear operands from stack
+
+Again, the result is returned in fp0. Note that BOTH operands
+are passed in single precision format.
+
+Exception reporting:
+--------------------
+The package takes exceptions according to the FPCR value upon subroutine
+entry. If an exception should be reported, then the package forces
+this exception using implemented floating-point instructions.
+For example, if the instruction being emulated should cause a
+floating-point Operand Error exception, then the library routine
+executes an FMUL of a zero and an infinity to force the OPERR
+exception. Although the FPIAR will be undefined for the enabled
+Operand Error exception handler, the user will at least be able
+to record that the event occurred.
+
+Miscellaneous:
+--------------
+The package does not attempt to correctly emulate instructions
+with Signalling NAN inputs. Use of SNANs should be avoided with
+this package.
+
+The fabs/fadd/fdiv/fint/fintrz/fmul/fneg/fsqrt/fsub entry points
+are provided for the convenience of older compilers that make
+subroutine calls for all fp instructions. The code does NOT emulate
+the instruction but rather simply executes it.

+68060 FLOATING-POINT SOFTWARE PACKAGE (Kernel version)
+-------------------------------------------------------
+
+The file fpsp.sa contains the 68060 Floating-Point Software
+Package. This package is essentially a set of exception handlers
+that can be integrated into an operating system.
+These exception handlers emulate Unimplemented FP instructions,
+instructions using unimplemented data types, and instructions
+using unimplemented addressing modes. In addition, this package
+includes exception handlers to provide full IEEE-754 compliant
+exception handling.
+
+Release file format:
+--------------------
+The file fpsp.sa is essentially a hexadecimal image of the
+release package. This is the ONLY format which will be supported.
+The hex image was created by assembling the source code and
+then converting the resulting binary output image into an
+ASCII text file. The hexadecimal numbers are listed
+using the Motorola Assembly Syntax assembler directive "dc.l"
+(define constant longword). The file can be converted to other
+assembly syntaxes by using any word processor with a global
+search and replace function.
+
+To assist in assembling and linking this module with other modules,
+the installer should add a symbolic label to the top of the file.
+This will allow calling routines to access the entry points
+of this package.
+
+The source code fpsp.s has also been included but only for
+documentation purposes.
+
+Release file structure:
+-----------------------
+
+(top of module)
+        -----------------
+        |               | - 128 byte-sized section
+   (1)  |   Call-Out    | - 4 bytes per entry (user fills these in)
+        |               | - example routines in fskeleton.s
+        -----------------
+        |               | - 8 bytes per entry
+   (2)  | Entry Point   | - user does "bra" or "jmp" to this address
+        |               |
+        -----------------
+        |               | - code section
+   (3)  ~               ~
+        |               |
+        -----------------
+(bottom of module)
+
+The first section of this module is the "Call-out" section. This section
+is NOT INCLUDED in fpsp.sa (an example "Call-out" section is provided at
+the end of the file fskeleton.s). The purpose of this section is to allow
+the FPSP routines to reference external functions that must be provided
+by the host operating system. This section MUST be exactly 128 bytes in
+size. There are 32 fields, each 4 bytes in size. Each field corresponds
+to a function required by the FPSP (these functions and their location are
+listed in "68060FPSP call-outs" below). Each field entry should contain
+the address of the corresponding function RELATIVE to the starting address
+of the "call-out" section. The "Call-out" section must sit adjacent to the
+fpsp.sa image in memory.
+
+The second section, the "Entry-point" section, is used by external routines
+to access the functions within the FPSP. Since the fpsp.sa hex file contains
+no symbol names, this section contains function entry points that are fixed
+with respect to the top of the package. The currently defined entry-points
+are listed in section "68060 FPSP entry points" below. A calling routine
+would simply execute a "bra" or "jmp" that jumped to the selected function
+entry-point.
+
+For example, if the 68060 hardware took a "Line-F Emulator" exception
+(vector #11), the operating system should execute something similar to:
+
+        bra     _060FPSP_TOP+128+48
+
+(_060FPSP_TOP is the starting address of the "Call-out" section; the "Call-out"
+section is 128 bytes long; and the F-Line FPSP handler entry point is located
+48 bytes from the top of the "Entry-point" section.)
+
+The third section is the code section. After entering through an "Entry-point",
+the entry code jumps to the appropriate emulation code within the code section.

+| _060_fpsp_done():
+|
+| This is the main exit point for the 68060 Floating-Point
+| Software Package. For a normal exit, all 060FPSP routines call this
+| routine. The operating system can do system dependent clean-up or
+| simply execute an "rte" as with the sample code below.
+|
+        .global         _060_fpsp_done
+_060_fpsp_done:
+        bral     _060_isp_done  | do the same as isp_done
+
+|
+| _060_real_ovfl():
+|
+| This is the exit point for the 060FPSP when an enabled overflow exception
+| is present. The routine below should point to the operating system handler
+| for enabled overflow conditions. The exception stack frame is an overflow
+| stack frame. The FP state frame holds the EXCEPTIONAL OPERAND.
+|
+| The sample routine below simply clears the exception status bit and

+68060 INTEGER SOFTWARE PACKAGE (Library version)
+-------------------------------------------------
+
+The file ilsp.s contains the "Library version" of the
+68060 Integer Software Package. Routines included in this
+module can be used to emulate 64-bit divide and multiply,
+and the "cmp2" instruction. These instructions are not
+implemented in hardware on the 68060 and normally take
+exception vector #61 "Unimplemented Integer Instruction".
+
+By re-compiling a program that uses these instructions, and
+making subroutine calls in place of the unimplemented
+instructions, a program can avoid the overhead associated with
+taking the exception.
+
+Release file format:
+--------------------
+The file ilsp.sa is essentially a hexadecimal image of the
+release package. This is the ONLY format which will be supported.
+The hex image was created by assembling the source code and
+then converting the resulting binary output image into an
+ASCII text file. The hexadecimal numbers are listed
+using the Motorola Assembly Syntax assembler directive "dc.l"
+(define constant longword). The file can be converted to other
+assembly syntaxes by using any word processor with a global
+search and replace function.
+
+To assist in assembling and linking this module with other modules,
+the installer should add a symbolic label to the top of the file.
+This will allow calling routines to access the entry points
+of this package.
+
+The source code ilsp.s has also been included but only for
+documentation purposes.
+
+Release file structure:
+-----------------------
+The file ilsp.sa contains an "Entry-Point" section and a
+code section. The ILSP has no "Call-Out" section. The first section
+is the "Entry-Point" section. In order to access a function in the
+package, a program must "bsr" or "jsr" to the location listed
+below in "68060ILSP Entry Points" that corresponds to the desired
+function. A branch instruction located at the selected entry point
+within the package will then enter the correct emulation code routine.
+
+The entry point addresses at the beginning of the package will remain
+fixed so that a program calling the routines will not have to be
+re-compiled with every new 68060ILSP release.
+
+For example, to use a 64-bit multiply instruction,
+do a "bsr" or "jsr" to the entry point defined by
+the 060ILSP entry table. A compiler generated code sequence
+for unsigned multiply could look like:
+
+# mulu.l <ea>,Dh:Dl
+# mulu.l _multiplier,%d1:%d0
+
+        subq.l  &0x8,%sp        # make room for result on stack
+        pea     (%sp)           # pass: result addr on stack
+        mov.l   %d0,-(%sp)      # pass: multiplicand on stack
+        mov.l   _multiplier,-(%sp) # pass: multiplier on stack
+        bsr.l   _060LISP_TOP+0x18 # branch to multiply routine
+        add.l   &0xc,%sp        # clear arguments from stack
+        mov.l   (%sp)+,%d1      # load result[63:32]
+        mov.l   (%sp)+,%d0      # load result[31:0]
+
+For a divide:
+
+# divu.l <ea>,Dr:Dq
+# divu.l _divisor,%d1:%d0
+
+        subq.l  &0x8,%sp        # make room for result on stack
+        pea     (%sp)           # pass: result addr on stack
+        mov.l   %d0,-(%sp)      # pass: dividend hi on stack
+        mov.l   %d1,-(%sp)      # pass: dividend hi on stack
+        mov.l   _divisor,-(%sp) # pass: divisor on stack
+        bsr.l   _060LISP_TOP+0x08 # branch to divide routine
+        add.l   &0xc,%sp        # clear arguments from stack
+        mov.l   (%sp)+,%d1      # load remainder
+        mov.l   (%sp)+,%d0      # load quotient
+
+The library routines also return the correct condition code
+register value. If this is important, then the caller of the library
+routine must make sure that the value isn't lost while popping
+other items off of the stack.
+
+An example of using the "cmp2" instruction is as follows:
+
+# cmp2.l <ea>,Rn
+# cmp2.l _bounds,%d0
+
+        pea     _bounds         # pass ptr to bounds
+        mov.l   %d0,-(%sp)      # pass Rn
+        bsr.l   _060LSP_TOP_+0x48 # branch to "cmp2" routine
+        mov.w   %cc,_tmp        # save off condition codes
+        addq.l  &0x8,%sp        # clear arguments from stack
+
+Exception reporting:
+--------------------
+If the instruction being emulated is a divide and the source
+operand is a zero, then the library routine, as its last
+instruction, executes an implemented divide using a zero
+source operand so that an "Integer Divide-by-Zero" exception
+will be taken. Although the exception stack frame will not
+point to the correct instruction, the user will at least be able
+to record that such an event occurred if desired.

+| _060_isp_done():
+|
+| This is and example main exit point for the Unimplemented Integer
+| Instruction exception handler. For a normal exit, the
+| _isp_unimp() branches to here so that the operating system
+| can do any clean-up desired. The stack frame is the
+| Unimplemented Integer Instruction stack frame with
+| the PC pointing to the instruction following the instruction
+| just emulated.
+| To simply continue execution at the next instruction, just
+| do an "rte".
+|
+| Linux/68k: If returning to user space, check for needed reselections.

+| _060_real_chk():
+|
+| This is an alternate exit point for the Unimplemented Integer
+| Instruction exception handler. If the instruction was a "chk2"
+| and the operand was out of bounds, then _isp_unimp() creates
+| a CHK exception stack frame from the Unimplemented Integer Instrcution
+| stack frame and branches to this routine.

+| _060_real_divbyzero:
+|
+| This is an alternate exit point for the Unimplemented Integer
+| Instruction exception handler isp_unimp(). If the instruction is a 64-bit
+| integer divide where the source operand is a zero, then the _isp_unimp()
+| creates a Divide-by-zero exception stack frame from the Unimplemented
+| Integer Instruction stack frame and branches to this routine.
+|
+| Remember that a trace exception may be pending. The code below performs
+| no action associated with the "chk" exception. If tracing is enabled,

+| stack frame and branches to the _real_trace() entry point.

+68060 INTEGER SOFTWARE PACKAGE (Kernel version)
+------------------------------------------------
+
+The file isp.sa contains the 68060 Integer Software Package.
+This package is essentially an exception handler that can be
+integrated into an operating system to handle the "Unimplemented
+Integer Instruction" exception vector #61.
+This exception is taken when any of the integer instructions
+not hardware implemented on the 68060 are encountered. The
+isp.sa provides full emulation support for these instructions.
+
+The unimplemented integer instructions are:
+        64-bit divide
+        64-bit multiply
+        movep
+        cmp2
+        chk2
+        cas (w/ a misaligned effective address)
+        cas2
+
+Release file format:
+--------------------
+The file isp.sa is essentially a hexadecimal image of the
+release package. This is the ONLY format which will be supported.
+The hex image was created by assembling the source code and
+then converting the resulting binary output image into an
+ASCII text file. The hexadecimal numbers are listed
+using the Motorola Assembly Syntax assembler directive "dc.l"
+(define constant longword). The file can be converted to other
+assembly syntaxes by using any word processor with a global
+search and replace function.
+
+To assist in assembling and linking this module with other modules,
+the installer should add a symbolic label to the top of the file.
+This will allow calling routines to access the entry points
+of this package.
+
+The source code isp.s has also been included but only for
+documentation purposes.
+
+Release file structure:
+-----------------------
+
+(top of module)
+        -----------------
+        |               | - 128 byte-sized section
+   (1)  |   Call-Out    | - 4 bytes per entry (user fills these in)
+        |               | - example routines in iskeleton.s
+        -----------------
+        |               | - 8 bytes per entry
+   (2)  | Entry Point   | - user does a "bra" or "jmp" to this address
+        |               |
+        -----------------
+        |               | - code section
+   (3)  ~               ~
+        |               |
+        -----------------
+(bottom of module)
+
+The first section of this module is the "Call-out" section. This section
+is NOT INCLUDED in isp.sa (an example "Call-out" section is provided at
+the end of the file iskeleton.s). The purpose of this section is to allow
+the ISP routines to reference external functions that must be provided
+by the host operating system. This section MUST be exactly 128 bytes in
+size. There are 32 fields, each 4 bytes in size. Each field corresponds
+to a function required by the ISP (these functions and their location are
+listed in "68060ISP call-outs" below). Each field entry should contain
+the address of the corresponding function RELATIVE to the starting address
+of the "call-out" section. The "Call-out" section must sit adjacent to the
+isp.sa image in memory.
+
+The second section, the "Entry-point" section, is used by external routines
+to access the functions within the ISP. Since the isp.sa hex file contains
+no symbol names, this section contains function entry points that are fixed
+with respect to the top of the package. The currently defined entry-points
+are listed in section "68060 ISP entry points" below. A calling routine
+would simply execute a "bra" or "jmp" that jumped to the selected function
+entry-point.
+
+For example, if the 68060 hardware took a "Unimplemented Integer Instruction"
+exception (vector #61), the operating system should execute something
+similar to:
+
+        bra     _060ISP_TOP+128+0
+
+(_060ISP_TOP is the starting address of the "Call-out" section; the "Call-out"
+section is 128 bytes long; and the Unimplemented Integer ISP handler entry
+point is located 0 bytes from the top of the "Entry-point" section.)
+
+The third section is the code section. After entering through an "Entry-point",
+the entry code jumps to the appropriate emulation code within the code section.

+0x038:  _060_isp_cas_restart
+
+Integrating cas/cas2:
+---------------------
+The instructions "cas2" and "cas" (when used with a misaligned effective
+address) take the Unimplemented Integer Instruction exception. When the
+060ISP is installed properly, these instructions will enter through the
+_060_isp_unimp() entry point of the ISP.
+
+After the 060ISP decodes the instruction type and fetches the appropriate
+data registers, and BEFORE the actual emulated transfers occur, the
+package calls either the "Call-out" _060_real_cas() or _060_real_cas2().
+If the emulation code provided by the 060ISP is sufficient for the
+host system (see isp.s source code), then these "Call-out"s should be
+made, by the system integrator, to point directly back into the package
+through the "Entry-point"s _060_isp_cas() or _060_isp_cas2().
+
+One other necessary action by the integrator is to supply the routines
+_060_real_lock_page() and _060_real_unlock_page(). These functions are
+defined further in iskeleton.s and the 68060 Software Package Specification.
+
+If the "core" emulation routines of either "cas" or "cas2" perform some
+actions which are too system-specific, then the system integrator must
+supply new emulation code. This new emulation code should reside within
+the functions _060_real_cas() or _060_real_cas2(). When this new emulation
+code has completed, then it should re-enter the 060ISP package through the
+"Entry-point" _060_isp_cas_finish() or _060_isp_cas2_finish().
+To see what the register state is upon entering _060_real_cas() or
+_060_real_cas2() and what it should be upon return to the package through
+_060_isp_cas_finish() or _060_isp_cas2_finish(), please refer to the
+source code in isp.s.

+| Each IO routine checks to see if the memory write/read is to/from user
+| or supervisor application space. The examples below use simple "move"
+| instructions for supervisor mode applications and call _copyin()/_copyout()
+| for user mode applications.
+| When installing the 060SP, the _copyin()/_copyout() equivalents for a
+| given operating system should be substituted.
+|
+| The addresses within the 060SP are guaranteed to be on the stack.
+| The result is that Unix processes are allowed to sleep as a consequence
+| of a page fault during a _copyout.
+|
+| Linux/68k: The _060_[id]mem_{read,write}_{byte,word,long} functions
+| (i.e. all the known length <= 4) are implemented by single moves
+| statements instead of (more expensive) copy{in,out} calls, if
+| working in user space

+#       Step 2. Let X = sgn * 2**k * 1.xxxxxxxx...x.                    #
+#               Note that k = -4, -3,..., or 3.                         #
+#               Define F = sgn * 2**k * 1.xxxx1, i.e. the first 5       #
+#               significant bits of X with a bit-1 attached at the 6-th #
+#               bit position. Define u to be u = (X-F) / (1 + X*F).     #
+#                                                                       #
+#       Step 3. Approximate arctan(u) by a polynomial poly.             #

+#       Step 4. Return arctan(F) + poly, arctan(F) is fetched from a    #
+#               table of values calculated beforehand. Exit.            #
+#                                                                       #

+#       Step 1. Filter out extreme cases of input argument.             #
+#               1.1     If |X| >= 2^(-65), go to Step 1.3.              #
+#               1.2     Go to Step 7.                                   #
+#               1.3     If |X| < 16380 log(2), go to Step 2.            #
+#               1.4     Go to Step 8.                                   #
+#       Notes:  The usual case should take the branches 1.1 -> 1.3 -> 2.#
+#               To avoid the use of floating-point comparisons, a       #
+#               compact representation of |X| is used. This format is a #
+#               32-bit integer, the upper (more significant) 16 bits    #
+#               are the sign and biased exponent field of |X|; the      #
+#               lower 16 bits are the 16 most significant fraction      #
+#               (including the explicit bit) bits of |X|. Consequently, #
+#               the comparisons in Steps 1.1 and 1.3 can be performed   #
+#               by integer comparison. Note also that the constant      #
+#               16380 log(2) used in Step 1.3 is also in the compact    #
+#               form. Thus taking the branch to Step 2 guarantees       #
+#               |X| < 16380 log(2). There is no harm to have a small    #
+#               number of cases where |X| is less than, but close to,   #
+#               16380 log(2) and the branch to Step 9 is taken.         #
+#                                                                       #
+#       Step 2. Calculate N = round-to-nearest-int( X * 64/log2 ).      #
+#               2.1     Set AdjFlag := 0 (indicates the branch 1.3 -> 2 #
+#                       was taken)                                      #
+#               2.2     N := round-to-nearest-integer( X * 64/log2 ).   #
+#               2.3     Calculate       J = N mod 64; so J = 0,1,2,..., #
+#                       or 63.                                          #
+#               2.4     Calculate       M = (N - J)/64; so N = 64M + J. #
+#               2.5     Calculate the address of the stored value of    #
+#                       2^(J/64).                                       #
+#               2.6     Create the value Scale = 2^M.                   #
+#       Notes:  The calculation in 2.2 is really performed by           #
+#                       Z := X * constant                               #
+#                       N := round-to-nearest-integer(Z)                #
+#               where                                                   #
+#                       constant := single-precision( 64/log 2 ).       #
+#                                                                       #
+#               Using a single-precision constant avoids memory         #
+#               access. Another effect of using a single-precision      #
+#               "constant" is that the calculated value Z is            #
+#                                                                       #

+#               This error has to be considered later in Steps 3 and 4. #
+#                                                                       #
+#       Step 3. Calculate X - N*log2/64.                                #
+#               3.1     R := X + N*L1,                                  #
+#                               where L1 := single-precision(-log2/64). #
+#               3.2     R := R + N*L2,                                  #
+#                               L2 := extended-precision(-log2/64 - L1).#
+#       Notes:  a) The way L1 and L2 are chosen ensures L1+L2           #
+#               approximate the value -log2/64 to 88 bits of accuracy.  #
+#               b) N*L1 is exact because N is no longer than 22 bits    #
+#               and L1 is no longer than 24 bits.                       #
+#               c) The calculation X+N*L1 is also exact due to          #
+#               cancellation. Thus, R is practically X+N(L1+L2) to full #
+#               64 bits.                                                #
+#               d) It is important to estimate how large can |R| be     #
+#               after Step 3.2.                                         #
+#                                                                       #
+#               N = rnd-to-int( X*64/log2 (1+eps) ), |eps|<=2^(-24)     #
+#               X*64/log2 (1+eps)       =       N + f,  |f| <= 0.5      #
+#               X*64/log2 - N   =       f - eps*X 64/log2               #
+#               X - N*log2/64   =       f*log2/64 - eps*X               #
+#                                                                       #
+#                                                                       #
+#               Now |X| <= 16446 log2, thus                             #
+#                                                                       #
+#                       |X - N*log2/64| <= (0.5 + 16446/2^(18))*log2/64 #
+#                                       <= 0.57 log2/64.                #
+#                This bound will be used in Step 4.                     #
+#                                                                       #
+#       Step 4. Approximate exp(R)-1 by a polynomial                    #
+#               p = R + R*R*(A1 + R*(A2 + R*(A3 + R*(A4 + R*A5))))      #
+#       Notes:  a) In order to reduce memory access, the coefficients   #
+#               are made as "short" as possible: A1 (which is 1/2), A4  #
+#               and A5 are single precision; A2 and A3 are double       #
+#               precision.                                              #
+#               b) Even with the restrictions above,                    #
+#                  |p - (exp(R)-1)| < 2^(-68.8) for all |R| <= 0.0062.  #
+#               Note that 0.0062 is slightly bigger than 0.57 log2/64.  #
+#               c) To fully utilize the pipeline, p is separated into   #
+#               two independent pieces of roughly equal complexities    #
+#                       p = [ R + R*S*(A2 + S*A4) ]     +               #
+#                               [ S*(A1 + S*(A3 + S*A5)) ]              #
+#               where S = R*R.                                          #
+#                                                                       #
+#       Step 5. Compute 2^(J/64)*exp(R) = 2^(J/64)*(1+p) by             #
+#                               ans := T + ( T*p + t)                   #
+#               where T and t are the stored values for 2^(J/64).       #
+#       Notes:  2^(J/64) is stored as T and t where T+t approximates    #
+#               2^(J/64) to roughly 85 bits; T is in extended precision #
+#               and t is in single precision. Note also that T is       #
+#               rounded to 62 bits so that the last two bits of T are   #
+#               zero. The reason for such a special form is that T-1,   #
+#               T-2, and T-8 will all be exact --- a property that will #
+#               give much more accurate computation of the function     #
+#               EXPM1.                                                  #
+#                                                                       #
+#       Step 6. Reconstruction of exp(X)                                #
+#                       exp(X) = 2^M * 2^(J/64) * exp(R).               #
+#               6.1     If AdjFlag = 0, go to 6.3                       #
+#               6.2     ans := ans * AdjScale                           #
+#               6.3     Restore the user FPCR                           #
+#               6.4     Return ans := ans * Scale. Exit.                #
+#       Notes:  If AdjFlag = 0, we have X = Mlog2 + Jlog2/64 + R,       #
+#               |M| <= 16380, and Scale = 2^M. Moreover, exp(X) will    #
+#               neither overflow nor underflow. If AdjFlag = 1, that    #
+#               means that                                              #
+#                       X = (M1+M)log2 + Jlog2/64 + R, |M1+M| >= 16380. #
+#               Hence, exp(X) may overflow or underflow or neither.     #
+#               When that is the case, AdjScale = 2^(M1) where M1 is    #
+#               approximately M. Thus 6.2 will never cause              #
+#               over/underflow. Possible exception in 6.4 is overflow   #
+#               or underflow. The inexact exception is not generated in #
+#               6.4. Although one can argue that the inexact flag       #
+#               should always be raised, to simulate that exception     #
+#               cost to much than the flag is worth in practical uses.  #
+#                                                                       #

+#       Notes:  For non-zero X, the inexact exception will always be    #
+#               raised by 7.3. That is the only exception raised by 7.3.#
+#               Note also that we use the FMOVEM instruction to move X  #
+#               in Step 7.1 to avoid unnecessary trapping. (Although    #
+#               the FMOVEM may not seem relevant since X is normalized, #
+#               the precaution will be useful in the library version of #
+#               this code where the separate entry for denormalized     #

+#       Note 1. There are 64 different possible values for F, thus 64   #
+#               log(F)'s need to be tabulated. Moreover, the values of  #
+#               1/F are also tabulated so that the division in (Y-F)/F  #

+#       Note 2. In Step 2 of lognp1, in order to preserved accuracy,    #
+#               the value Y-F has to be calculated carefully when       #
+#               1/2 <= X < 3/2.                                         #

+#       Note 3. To fully exploit the pipeline, polynomials are usually  #
+#               separated into two parts evaluated independently before #
+#               being added up.                                         #

+#       This file is appended to the top of the 060FPSP package
+# and contains the entry points into the package. The user, in
+# effect, branches to one of the branch table entries located
+# after _060FPSP_TABLE.
+#       Also, subroutine stubs exist in this file (_fpsp_done for
+# example) that are referenced by the FPSP package itself in order
+# to call a given routine. The stub routine actually performs the
+# callout. The FPSP code does a "bsr" to the stub routine. This
+# extra layer of hierarchy adds a slight performance penalty but
+# it makes the FPSP code easier to read and more mainatinable.

+# ALGORITHM *********************************************************** #
+#       On the 060, if an FP overflow is present as the result of any   #
+# instruction, the 060 will take an overflow exception whether the      #
+# exception is enabled or disabled in the FPCR. For the disabled case,  #
+# This handler emulates the instruction to determine what the correct   #
+# default result should be for the operation. This default result is    #
+# then stored in either the FP regfile, data regfile, or memory.        #
+# Finally, the handler exits through the "callout" _fpsp_done()         #
+# denoting that no exceptional conditions exist within the machine.     #
+#       If the exception is enabled, then this handler must create the  #
+# exceptional operand and plave it in the fsave state frame, and store  #
+# the default result (only if the instruction is opclass 3). For        #
+# exceptions enabled, this handler must exit through the "callout"      #
+# _real_ovfl() so that the operating system enabled overflow handler    #
+# can handle this case.                                                 #
+#       Two other conditions exist. First, if overflow was disabled     #
+# but the inexact exception was enabled, this handler must exit         #
+# through the "callout" _real_inex() regardless of whether the result   #
+# was inexact.                                                          #
+#       Also, in the case of an opclass three instruction where         #
+# overflow was disabled and the trace exception was enabled, this       #
+# handler must exit through the "callout" _real_trace().                #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       On the 060, if an FP underflow is present as the result of any  #
+# instruction, the 060 will take an underflow exception whether the     #
+# exception is enabled or disabled in the FPCR. For the disabled case,  #
+# This handler emulates the instruction to determine what the correct   #
+# default result should be for the operation. This default result is    #
+# then stored in either the FP regfile, data regfile, or memory.        #
+# Finally, the handler exits through the "callout" _fpsp_done()         #
+# denoting that no exceptional conditions exist within the machine.     #
+#       If the exception is enabled, then this handler must create the  #
+# exceptional operand and plave it in the fsave state frame, and store  #
+# the default result (only if the instruction is opclass 3). For        #
+# exceptions enabled, this handler must exit through the "callout"      #
+# _real_unfl() so that the operating system enabled overflow handler    #
+# can handle this case.                                                 #
+#       Two other conditions exist. First, if underflow was disabled    #
+# but the inexact exception was enabled and the result was inexact,     #
+# this handler must exit through the "callout" _real_inex().            #
+# was inexact.                                                          #
+#       Also, in the case of an opclass three instruction where         #
+# underflow was disabled and the trace exception was enabled, this      #
+# handler must exit through the "callout" _real_trace().                #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       Two main instruction types can enter here: (1) DENORM or UNNORM #
+# unimplemented data types. These can be either opclass 0,2 or 3        #
+# instructions, and (2) PACKED unimplemented data format instructions   #
+# also of opclasses 0,2, or 3.                                          #
+#       For UNNORM/DENORM opclass 0 and 2, the handler fetches the src  #
+# operand from the fsave state frame and the dst operand (if dyadic)    #
+# from the FP register file. The instruction is then emulated by        #
+# choosing an emulation routine from a table of routines indexed by     #
+# instruction type. Once the instruction has been emulated and result   #
+# saved, then we check to see if any enabled exceptions resulted from   #
+# instruction emulation. If none, then we exit through the "callout"    #
+# _fpsp_done(). If there is an enabled FP exception, then we insert     #
+# this exception into the FPU in the fsave state frame and then exit    #
+# through _fpsp_done().                                                 #
+#       PACKED opclass 0 and 2 is similar in how the instruction is     #
+# emulated and exceptions handled. The differences occur in how the     #
+# handler loads the packed op (by calling get_packed() routine) and     #
+# by the fact that a Trace exception could be pending for PACKED ops.   #
+# If a Trace exception is pending, then the current exception stack     #
+# frame is changed to a Trace exception stack frame and an exit is      #
+# made through _real_trace().                                           #
+#       For UNNORM/DENORM opclass 3, the actual move out to memory is   #
+# performed by calling the routine fout(). If no exception should occur #
+# as the result of emulation, then an exit either occurs through        #
+# _fpsp_done() or through _real_trace() if a Trace exception is pending #
+# (a Trace stack frame must be created here, too). If an FP exception   #
+# should occur, then we must create an exception stack frame of that    #
+# type and jump to either _real_snan(), _real_operr(), _real_inex(),    #
+# _real_unfl(), or _real_ovfl() as appropriate. PACKED opclass 3        #
+# emulation is performed in a similar manner.                           #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       This exception handles 3 types of operations:                   #
+# (1) FP Instructions using extended precision or packed immediate      #
+#     addressing mode.                                                  #
+# (2) The "fmovm.x" instruction w/ dynamic register specification.      #
+# (3) The "fmovm.l" instruction w/ 2 or 3 control registers.            #
+#                                                                       #
+#       For immediate data operations, the data is read in w/ a         #
+# _mem_read() "callout", converted to FP binary (if packed), and used   #
+# as the source operand to the instruction specified by the instruction #
+# word. If no FP exception should be reported ads a result of the       #
+# emulation, then the result is stored to the destination register and  #
+# the handler exits through _fpsp_done(). If an enabled exc has been    #
+# signalled as a result of emulation, then an fsave state frame         #
+# corresponding to the FP exception type must be entered into the 060   #
+# FPU before exiting. In either the enabled or disabled cases, we       #
+# must also check if a Trace exception is pending, in which case, we    #
+# must create a Trace exception stack frame from the current exception  #
+# stack frame. If no Trace is pending, we simply exit through           #
+# _fpsp_done().                                                         #
+#       For "fmovm.x", call the routine fmovm_dynamic() which will      #
+# decode and emulate the instruction. No FP exceptions can be pending   #
+# as a result of this operation emulation. A Trace exception can be     #
+# pending, though, which means the current stack frame must be changed  #
+# to a Trace stack frame and an exit made through _real_trace().        #
+# For the case of "fmovm.x Dn,-(a7)", where the offending instruction   #
+# was executed from supervisor mode, this handler must store the FP     #
+# register file values to the system stack by itself since              #
+# fmovm_dynamic() can't handle this. A normal exit is made through      #
+# fpsp_done().                                                          #
+#       For "fmovm.l", fmovm_ctrl() is used to emulate the instruction. #
+# Again, a Trace exception may be pending and an exit made through      #
+# _real_trace(). Else, a normal exit is made through _fpsp_done().      #
+#                                                                       #
+#       Before any of the above is attempted, it must be checked to     #
+# see if the FPU is disabled. Since the "Unimp <ea>" exception is taken #
+# before the "FPU disabled" exception, but the "FPU disabled" exception #
+# has higher priority, we check the disabled bit in the PCR. If set,    #
+# then we must create an 8 word "FPU disabled" exception stack frame    #
+# from the current 4 word exception stack frame. This includes          #
+# reproducing the effective address of the instruction to put on the    #
+# new stack frame.                                                      #
+#                                                                       #
+#       In the process of all emulation work, if a _mem_read()          #
+# "callout" returns a failing result indicating an access error, then   #
+# we must create an access error stack frame from the current stack     #
+# frame. This information includes a faulting address and a fault-      #
+# status-longword. These are created within this handler.               #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       In a system where the FP Operr exception is enabled, the goal   #
+# is to get to the handler specified at _real_operr(). But, on the 060, #
+# for opclass zero and two instruction taking this exception, the       #
+# input operand in the fsave frame may be incorrect for some cases      #
+# and needs to be corrected. This handler calls fix_skewed_ops() to     #
+# do just this and then exits through _real_operr().                    #
+#       For opclass 3 instructions, the 060 doesn't store the default   #
+# operr result out to memory or data register file as it should.        #
+# This code must emulate the move out before finally exiting through    #
+# _real_inex(). The move out, if to memory, is performed using          #
+# _mem_write() "callout" routines that may return a failing result.     #
+# In this special case, the handler must exit through facc_out()        #
+# which creates an access error stack frame from the current operr      #
+# stack frame.                                                          #

+#       - The system stack is unchanged                                 #
+#       - The fsave frame contains the adjusted src op for opclass 0,2  #
+#                                                                       #
+# ALGORITHM *********************************************************** #
+#       In a system where the FP SNAN exception is enabled, the goal    #
+# is to get to the handler specified at _real_snan(). But, on the 060,  #
+# for opclass zero and two instructions taking this exception, the      #
+# input operand in the fsave frame may be incorrect for some cases      #
+# and needs to be corrected. This handler calls fix_skewed_ops() to     #
+# do just this and then exits through _real_snan().                     #
+#       For opclass 3 instructions, the 060 doesn't store the default   #
+# SNAN result out to memory or data register file as it should.         #
+# This code must emulate the move out before finally exiting through    #
+# _real_snan(). The move out, if to memory, is performed using          #
+# _mem_write() "callout" routines that may return a failing result.     #
+# In this special case, the handler must exit through facc_out()        #
+# which creates an access error stack frame from the current SNAN       #
+# stack frame.                                                          #
+#       For the case of an extended precision opclass 3 instruction,    #
+# if the effective addressing mode was -() or ()+, then the address     #
+# register must get updated by calling _calc_ea_fout(). If the <ea>     #
+# was -(a7) from supervisor mode, then the exception frame currently    #
+# on the system stack must be carefully moved "down" to make room       #
+# for the operand being moved.                                          #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       In a system where the FP Inexact exception is enabled, the goal #
+# is to get to the handler specified at _real_inex(). But, on the 060,  #
+# for opclass zero and two instruction taking this exception, the       #
+# hardware doesn't store the correct result to the destination FP       #
+# register as did the '040 and '881/2. This handler must emulate the    #
+# instruction in order to get this value and then store it to the       #
+# correct register before calling _real_inex().                         #
+#       For opclass 3 instructions, the 060 doesn't store the default   #
+# inexact result out to memory or data register file as it should.      #
+# This code must emulate the move out by calling fout() before finally  #
+# exiting through _real_inex().                                         #
+#                                                                       #

+#       There are two main cases of instructions that may enter here to #
+# be emulated: (1) the FPgen instructions, most of which were also      #
+# unimplemented on the 040, and (2) "ftrapcc", "fscc", and "fdbcc".     #
+#       For the first set, this handler calls the routine load_fop()    #
+# to load the source and destination (for dyadic) operands to be used   #
+# for instruction emulation. The correct emulation routine is then      #
+# chosen by decoding the instruction type and indexing into an          #
+# emulation subroutine index table. After emulation returns, this       #
+# handler checks to see if an exception should occur as a result of the #
+# FP instruction emulation. If so, then an FP exception of the correct  #
+# type is inserted into the FPU state frame using the "frestore"        #
+# instruction before exiting through _fpsp_done(). In either the        #
+# exceptional or non-exceptional cases, we must check to see if the     #
+# Trace exception is enabled. If so, then we must create a Trace        #
+# exception frame from the current exception frame and exit through     #
+# _real_trace().                                                        #
+#       For "fdbcc", "ftrapcc", and "fscc", the emulation subroutines   #
+# _fdbcc(), _ftrapcc(), and _fscc() respectively are used. All three    #
+# may flag that a BSUN exception should be taken. If so, then the       #
+# current exception stack frame is converted into a BSUN exception      #
+# stack frame and an exit is made through _real_bsun(). If the          #
+# instruction was "ftrapcc" and a Trap exception should result, a Trap  #
+# exception stack frame is created from the current frame and an exit   #
+# is made through _real_trap(). If a Trace exception is pending, then   #
+# a Trace exception frame is created from the current frame and a jump  #
+# is made to _real_trace(). Finally, if none of these conditions exist, #
+# then the handler exits though the callout _fpsp_done().               #

+#       Notes:  The usual case should take the branches 1.1 -> 1.3 -> 2.#
+#               To avoid the use of floating-point comparisons, a       #
+#               compact representation of |X| is used. This format is a #
+#               32-bit integer, the upper (more significant) 16 bits    #
+#               are the sign and biased exponent field of |X|; the      #
+#               lower 16 bits are the 16 most significant fraction      #
+#               (including the explicit bit) bits of |X|. Consequently, #
+#               the comparisons in Steps 1.1 and 1.3 can be performed   #
+#               by integer comparison. Note also that the constant      #
+#               16380 log(2) used in Step 1.3 is also in the compact    #
+#               form. Thus taking the branch to Step 2 guarantees       #
+#               |X| < 16380 log(2). There is no harm to have a small    #
+#               number of cases where |X| is less than, but close to,   #
+#               16380 log(2) and the branch to Step 9 is taken.         #

+#               Using a single-precision constant avoids memory         #

+#                               L2 := extended-precision(-log2/64 - L1).#
+#       Notes:  a) The way L1 and L2 are chosen ensures L1+L2           #
+#               approximate the value -log2/64 to 88 bits of accuracy.  #
+#               b) N*L1 is exact because N is no longer than 22 bits    #
+#               and L1 is no longer than 24 bits.                       #
+#               c) The calculation X+N*L1 is also exact due to          #
+#               cancellation. Thus, R is practically X+N(L1+L2) to full #
+#               64 bits.                                                #

+#               neither overflow nor underflow. If AdjFlag = 1, that    #

+#               6.4. Although one can argue that the inexact flag       #
+#               should always be raised, to simulate that exception     #

+#       Implementation Notes:                                           #
+#       Note 1. There are 64 different possible values for F, thus 64   #
+#               log(F)'s need to be tabulated. Moreover, the values of  #
+#               1/F are also tabulated so that the division in (Y-F)/F  #
+#               can be performed by a multiplication.                   #
+#                                                                       #
+#       Note 2. In Step 2 of lognp1, in order to preserved accuracy,    #
+#               the value Y-F has to be calculated carefully when       #
+#               1/2 <= X < 3/2.                                         #

+#       Note 3. To fully exploit the pipeline, polynomials are usually  #
+#               separated into two parts evaluated independently before #
+#               being added up.                                         #

+#       Handle NANs, zeroes, and infinities as special cases. Separate  #
+# norms/denorms into ext/sgl/dbl precisions. Extended precision can be  #
+# emulated by simply setting sign bit. Sgl/dbl operands must be scaled  #
+# and an actual fneg performed to see if overflow/underflow would have  #
+# occurred. If so, return default underflow/overflow result. Else,      #
+# scale the result exponent and return result. FPSR gets set based on   #
+# the result value.                                                     #

+#       Handle NANs, infinities, and zeroes as special cases. Divide    #
+# norms into extended, single, and double precision.                    #
+#       Simply clear sign for extended precision norm. Ext prec denorm  #
+# gets an EXOP created for it since it's an underflow.                  #
+#       Double and single precision can overflow and underflow. First,  #
+# scale the operand such that the exponent is zero. Perform an "fabs"   #
+# using the correct rnd mode/prec. Check to see if the original         #
+# exponent would take an exception. If so, use unf_res() or ovf_res()   #
+# to calculate the default result. Also, create the EXOP for the        #
+# exceptional case. If no exception should occur, insert the correct    #
+# result exponent and return.                                           #

+#       Handle NANs, infinities, and zeroes as special cases. Divide    #

+#       For norms/denorms, scale the exponents such that a multiply     #
+# instruction won't cause an exception. Use the regular fsglmul to      #
+# compute a result. Check if the regular operands would have taken      #
+# an exception. If so, return the default overflow/underflow result     #
+# and return the EXOP if exceptions are enabled. Else, scale the        #
+# result operand to the proper exponent.                                #

+#       Handle NANs, infinities, and zeroes as special cases. Divide    #
+# norms/denorms into ext/sgl/dbl precision.                             #
+#       For norms/denorms, scale the exponents such that a sqrt         #
+# instruction won't cause an exception. Use the regular fsqrt to        #
+# compute a result. Check if the regular operands would have taken      #
+# an exception. If so, return the default overflow/underflow result     #
+# and return the EXOP if exceptions are enabled. Else, scale the        #
+# result operand to the proper exponent.                                #

+# to see whether the condition (specified by the stacked FPSR) is true  #
+# or false.                                                             #

+# bits are set in the stacked FPSR. If the BSUN exception is enabled,   #
+# the fbsun_flg is set in the SPCOND_FLG location on the stack. If an   #
+# enabled BSUN should not be flagged and the predicate is true, then    #
+# the result is stored to the data register file or memory              #

+#       If memory access doesn't fail:                                  #
+#               FP_SRC(a6) = source operand in extended precision       #
+#               FP_DST(a6) = destination operand in extended precision  #
+#                                                                       #
+# ALGORITHM *********************************************************** #
+#       This is called from the Unimplemented FP exception handler in   #
+# order to load the source and maybe destination operand into           #
+# FP_SRC(a6) and FP_DST(a6). If the instruction was opclass zero, load  #
+# the source and destination from the FP register file. Set the optype  #
+# tags for both if dyadic, one for monadic. If a number is an UNNORM,   #
+# convert it to a DENORM or a ZERO.                                     #
+#       If the instruction is opclass two (memory->reg), then fetch     #
+# the destination from the register file and the source operand from    #
+# memory. Tag and fix both as above w/ opclass zero instructions.       #
+#       If the source operand is byte,word,long, or single, it may be   #
+# in the data register file. If it's actually out in memory, use one of #
+# the mem_read() routines to fetch it. If the mem_read() access returns #
+# a failing value, exit through the special facc_in() routine which     #
+# will create an access error exception frame from the current exception #
+# frame.                                                                #
+#       Immediate data and regular data accesses are separated because  #
+# if an immediate data access fails, the resulting fault status         #
+# longword stacked for the access error exception must have the         #
+# instruction bit set.                                                  #

+#       fp0 : intermediate underflow or overflow result if              #
+#             OVFL/UNFL occurred for a sgl or dbl operand               #
+#                                                                       #
+# ALGORITHM *********************************************************** #
+#       This routine is accessed by many handlers that need to do an    #
+# opclass three move of an operand out to memory.                       #
+#       Decode an fmove out (opclass 3) instruction to determine if     #
+# it's b,w,l,s,d,x, or p in size. b,w,l can be stored to either a data  #
+# register or memory. The algorithm uses a standard "fmove" to create   #
+# the rounded result. Also, since exceptions are disabled, this also    #
+# create the correct OPERR default result if appropriate.               #
+#       For sgl or dbl precision, overflow or underflow can occur. If   #
+# either occurs and is enabled, the EXOP.                               #
+#       For extended precision, the stacked <ea> must be fixed along    #
+# w/ the address index register as appropriate w/ _calc_ea_fout(). If   #
+# the source is a denorm and if underflow is enabled, an EXOP must be   #
+# created.                                                              #
+#       For packed, the k-factor must be fetched from the instruction   #
+# word or a data register. The <ea> must be fixed as w/ extended        #
+# precision. Then, bindec() is called to create the appropriate         #
+# packed result.                                                        #
+#       If at any time an access error is flagged by one of the move-   #
+# to-memory routines, then a special exit must be made so that the      #
+# access error can be handled properly.                                 #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       Convert the input operand to "internal format" which means the  #
+# exponent is extended to 16 bits and the sign is stored in the unused  #
+# portion of the extended precison operand. Denormalize the number      #
+# according to the scale factor passed in d0. Then, round the           #
+# denormalized result.                                                  #
+#       Set the FPSR_exc bits as appropriate but return the cc bits in  #
+# d0 in case the caller doesn't want to save them (as is the case for   #
+# fmove out).                                                           #
+#       unf_res4() for fsglmul/fsgldiv forces the denorm to extended    #

+#  For adjusted exponents which have an absolute value greater than 27*,
+#  this routine calculates the amount needed to normalize the mantissa
+#  for the adjusted exponent.  That number is subtracted from the exp
+#  if the exp was positive, and added if it was negative.  The purpose
+#  of this is to reduce the value of the exponent and the possibility
+#  of error in calculation of pwrten.
+#
+#  1. Branch on the sign of the adjusted exponent.
+#  2p.(positive exp)
+#   2. Check M16 and the digits in lwords 2 and 3 in decending order.
+#   3. Add one for each zero encountered until a non-zero digit.
+#   4. Subtract the count from the exp.
+#   5. Check if the exp has crossed zero in #3 above; make the exp abs
+#          and set SE.
+#       6. Multiply the mantissa by 10**count.

+#   2. Check the digits in lwords 3 and 2 in decending order.
+#   3. Add one for each zero encountered until a non-zero digit.

+#  *Why 27?  If the adjusted exponent is within -28 < expA < 28, than
+#   any adjustment due to append/strip zeros will drive the resultane
+#   exponent towards zero.  Since all pwrten constants with a power

+#       0x10(sp) = points to location of remainder/quotient.            #
+#                  remainder is in first longword, quotient is in 2nd.  #

+# ALGORITHM *********************************************************** #
+#       If the operands are signed, make them unsigned and save the     #
+# sign info for later. Separate out special cases like divide-by-zero   #
+# or 32-bit divides if possible. Else, use a special math algorithm     #
+# to calculate the result.                                              #
+#       Restore sign info if signed instruction. Set the condition      #
+# codes before performing the final "rts". If the divisor was equal to  #
+# zero, then perform a divide-by-zero using a 16-bit implemented        #
+# divide instruction. This way, the operating system can record that    #
+# the event occurred even though it may not point to the correct place. #
+#                                                                       #

+#       In the interest of simplicity, all operands are converted to    #
+# longword size whether the operation is byte, word, or long. The       #
+# bounds are sign extended accordingly. If Rn is a data regsiter, Rn is #
+# also sign extended. If Rn is an address register, it need not be sign #
+# extended since the full register is always used.                      #
+#       The condition codes are set correctly before the final "rts".   #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       This handler fetches the first instruction longword from        #
+# memory and decodes it to determine which of the unimplemented         #
+# integer instructions caused this exception. This handler then calls   #
+# one of _mul64(), _div64(), _moveperipheral(), _compandset(),          #
+# _compandset2(), or _chk2_cmp2() as appropriate.                       #
+#       Some of these instructions, by their nature, may produce other  #
+# types of exceptions. "div" can produce a divide-by-zero exception,    #
+# and "chk2" can cause a "Chk" exception. In both cases, the current    #
+# exception stack frame must be converted to an exception stack frame   #
+# of the correct exception type and an exit must be made through        #
+# _real_divbyzero() or _real_chk() as appropriate. In addition, all     #
+# instructions may be executing while Trace is enabled. If so, then     #
+# a Trace exception stack frame must be created and an exit made        #
+# through _real_trace().                                                #
+#       Meanwhile, if any read or write to memory using the             #
+# _mem_{read,write}() "callout"s returns a failing value, then an       #
+# access error frame must be created and an exit made through           #
+# _real_access().                                                       #
+#       If none of these occur, then a normal exit is made through      #
+# _isp_done().                                                          #
+#                                                                       #
+#       This handler, upon entry, saves almost all user-visible         #
+# address and data registers to the stack. Although this may seem to    #
+# cause excess memory traffic, it was found that due to having to       #
+# access these register files for things like data retrieval and <ea>   #
+# calculations, it was more efficient to have them on the stack where   #
+# they could be accessed by indexing rather than to make subroutine     #
+# calls to retrieve a register of a particular index.                   #
+#                                                                       #

+#       First, calculate the effective address, then fetch the byte,    #
+# word, or longword sized operands. Then, in the interest of            #
+# simplicity, all operands are converted to longword size whether the   #
+# operation is byte, word, or long. The bounds are sign extended        #
+# accordingly. If Rn is a data regsiter, Rn is also sign extended. If   #
+# Rn is an address register, it need not be sign extended since the     #
+# full register is always used.                                         #
+#       The comparisons are made and the condition codes calculated.    #
+# If the instruction is chk2 and the Rn value is out-of-bounds, set     #
+# the ichk_flg in SPCOND_FLG.                                           #
+#       If the memory fetch returns a failing value, pass the failing   #
+# address and FSLW to the isp_dacc() routine.                           #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       First, decode the operand location. If it's in Dn, fetch from   #
+# the stack. If it's in memory, use _calc_ea() to calculate the         #
+# effective address. Use _dmem_read_long() to fetch at that address.    #
+# Unless the operand is immediate data. Then use _imem_read_long().     #
+# Send failures to isp_dacc() or isp_iacc() as appropriate.             #
+#       If the operands are signed, make them unsigned and save the     #
+# sign info for later. Separate out special cases like divide-by-zero   #
+# or 32-bit divides if possible. Else, use a special math algorithm     #
+# to calculate the result.                                              #
+#       Restore sign info if signed instruction. Set the condition      #
+# codes. Set idbyz_flg in SPCOND_FLG if divisor was zero. Store the     #
+# quotient and remainder in the appropriate data registers on the stack.#
+#                                                                       #

+#       First, decode the operand location. If it's in Dn, fetch from   #
+# the stack. If it's in memory, use _calc_ea() to calculate the         #
+# effective address. Use _dmem_read_long() to fetch at that address.    #
+# Unless the operand is immediate data. Then use _imem_read_long().     #
+# Send failures to isp_dacc() or isp_iacc() as appropriate.             #
+#       If the operands are signed, make them unsigned and save the     #
+# sign info for later. Perform the multiplication using 16x16->32       #
+# unsigned multiplies and "add" instructions. Store the high and low    #
+# portions of the result in the appropriate data registers on the       #
+# stack. Calculate the condition codes, also.                           #

+# operands.                                                             #
+#       Next, call the external routine _real_lock_page() so that the   #
+# operating system can keep this page from being paged out while we're  #
+# in this routine. If this call fails, jump to _cas_terminate2().       #
+#       The routine then branches to _real_cas(). This external routine #
+# that actually emulates cas can be supplied by the external os or      #
+# made to point directly back into the 060ISP which has a routine for   #
+# this purpose.                                                         #

+#       Either way, after emulation, the package is re-entered at       #
+# _isp_cas_finish(). This routine re-compares the operands in order to  #
+# set the condition codes. Finally, these routines will call            #
+# _real_unlock_page() in order to unlock the pages that were previously #
+# locked.                                                               #

+# _isp_cas_restart():                                                   #

+# unimplemented integer instruction frame.                              #
+#       Also, the package enters here if a call to _real_lock_page()    #
+# fails.                                                                #

+#                                                                       #
+# ALGORITHM *********************************************************** #
+#       (1) Make several copies of the effective address.               #
+#       (2) Save current SR; Then mask off all maskable interrupts.     #
+#       (3) Save current SFC/DFC (ASSUMED TO BE EQUAL!!!); Then set     #
+#           according to whether exception occurred in user or          #
+#           supervisor mode.                                            #
+#       (4) Use "plpaw" instruction to pre-load ATC with effective      #
+#           address pages(s). THIS SHOULD NOT FAULT!!! The relevant     #
+#           page(s) should have already been made resident prior to     #
+#           entering this routine.                                      #
+#       (5) Push the operand lines from the cache w/ "cpushl".          #
+#           In the 68040, this was done within the locked region. In    #
+#           the 68060, it is done outside of the locked region.         #
+#       (6) Use "plpar" instruction to do a re-load of ATC entries for  #
+#           ADDR1 since ADDR2 entries may have pushed ADDR1 out of the  #
+#           ATC.                                                        #
+#       (7) Pre-fetch the core emulation instructions by executing      #
+#           one branch within each physical line (16 bytes) of the code #
+#           before actually executing the code.                         #
+#       (8) Load the BUSCR w/ the bus lock value.                       #
+#       (9) Fetch the source operands using "moves".                    #
+#       (10)Do the compares. If both equal, go to step (13).            #
+#       (11)Unequal. No update occurs. But, we do write the DST1 op     #
+#           back to itself (as w/ the '040) so we can gracefully unlock #
+#           the bus (and assert LOCKE*) using BUSCR and the final move. #
+#       (12)Exit.                                                       #
+#       (13)Write update operand to the DST locations. Use BUSCR to     #
+#           assert LOCKE* for the final write operation.                #
+#       (14)Exit.                                                       #
+#                                                                       #
+#       The algorithm is actually implemented slightly differently      #
+# depending on the size of the operation and the misalignment of the    #
+# operands. A misaligned operand must be written in aligned chunks or   #
+# else the BUSCR register control gets confused.                        #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       (1) Make several copies of the effective address.               #
+#       (2) Save current SR; Then mask off all maskable interrupts.     #
+#       (3) Save current DFC/SFC (ASSUMED TO BE EQUAL!!!); Then set     #
+#           SFC/DFC according to whether exception occurred in user or  #
+#           supervisor mode.                                            #
+#       (4) Use "plpaw" instruction to pre-load ATC with efective       #
+#           address page(s). THIS SHOULD NOT FAULT!!! The relevant      #
+#           page(s) should have been made resident prior to entering    #
+#           this routine.                                               #
+#       (5) Push the operand lines from the cache w/ "cpushl".          #
+#           In the 68040, this was done within the locked region. In    #
+#           the 68060, it is done outside of the locked region.         #
+#       (6) Pre-fetch the core emulation instructions by executing one  #
+#           branch within each physical line (16 bytes) of the code     #
+#           before actually executing the code.                         #
+#       (7) Load the BUSCR with the bus lock value.                     #
+#       (8) Fetch the source operand.                                   #
+#       (9) Do the compare. If equal, go to step (12).                  #
+#       (10)Unequal. No update occurs. But, we do write the DST op back #
+#           to itself (as w/ the '040) so we can gracefully unlock      #
+#           the bus (and assert LOCKE*) using BUSCR and the final move. #
+#       (11)Exit.                                                       #
+#       (12)Write update operand to the DST location. Use BUSCR to      #
+#           assert LOCKE* for the final write operation.                #
+#       (13)Exit.                                                       #

+#       The algorithm is actually implemented slightly differently      #
+# depending on the size of the operation and the misalignment of the    #
+# operand. A misaligned operand must be written in aligned chunks or    #

+#       This file is appended to the top of the 060FPSP package
+# and contains the entry points into the package. The user, in
+# effect, branches to one of the branch table entries located
+# after _060FPSP_TABLE.
+#       Also, subroutine stubs exist in this file (_fpsp_done for
+# example) that are referenced by the FPSP package itself in order
+# to call a given routine. The stub routine actually performs the
+# callout. The FPSP code does a "bsr" to the stub routine. This
+# extra layer of hierarchy adds a slight performance penalty but
+# it makes the FPSP code easier to read and more mainatinable.

+# ALGORITHM *********************************************************** #
+#       On the 060, if an FP overflow is present as the result of any   #
+# instruction, the 060 will take an overflow exception whether the      #
+# exception is enabled or disabled in the FPCR. For the disabled case,  #
+# This handler emulates the instruction to determine what the correct   #
+# default result should be for the operation. This default result is    #
+# then stored in either the FP regfile, data regfile, or memory.        #
+# Finally, the handler exits through the "callout" _fpsp_done()         #
+# denoting that no exceptional conditions exist within the machine.     #
+#       If the exception is enabled, then this handler must create the  #
+# exceptional operand and plave it in the fsave state frame, and store  #
+# the default result (only if the instruction is opclass 3). For        #
+# exceptions enabled, this handler must exit through the "callout"      #
+# _real_ovfl() so that the operating system enabled overflow handler    #
+# can handle this case.                                                 #
+#       Two other conditions exist. First, if overflow was disabled     #
+# but the inexact exception was enabled, this handler must exit         #
+# through the "callout" _real_inex() regardless of whether the result   #
+# was inexact.                                                          #
+#       Also, in the case of an opclass three instruction where         #
+# overflow was disabled and the trace exception was enabled, this       #
+# handler must exit through the "callout" _real_trace().                #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       On the 060, if an FP underflow is present as the result of any  #
+# instruction, the 060 will take an underflow exception whether the     #
+# exception is enabled or disabled in the FPCR. For the disabled case,  #
+# This handler emulates the instruction to determine what the correct   #
+# default result should be for the operation. This default result is    #
+# then stored in either the FP regfile, data regfile, or memory.        #
+# Finally, the handler exits through the "callout" _fpsp_done()         #
+# denoting that no exceptional conditions exist within the machine.     #
+#       If the exception is enabled, then this handler must create the  #
+# exceptional operand and plave it in the fsave state frame, and store  #
+# the default result (only if the instruction is opclass 3). For        #
+# exceptions enabled, this handler must exit through the "callout"      #
+# _real_unfl() so that the operating system enabled overflow handler    #
+# can handle this case.                                                 #
+#       Two other conditions exist. First, if underflow was disabled    #
+# but the inexact exception was enabled and the result was inexact,     #
+# this handler must exit through the "callout" _real_inex().            #
+# was inexact.                                                          #
+#       Also, in the case of an opclass three instruction where         #
+# underflow was disabled and the trace exception was enabled, this      #
+# handler must exit through the "callout" _real_trace().                #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       Two main instruction types can enter here: (1) DENORM or UNNORM #
+# unimplemented data types. These can be either opclass 0,2 or 3        #
+# instructions, and (2) PACKED unimplemented data format instructions   #
+# also of opclasses 0,2, or 3.                                          #
+#       For UNNORM/DENORM opclass 0 and 2, the handler fetches the src  #
+# operand from the fsave state frame and the dst operand (if dyadic)    #
+# from the FP register file. The instruction is then emulated by        #
+# choosing an emulation routine from a table of routines indexed by     #
+# instruction type. Once the instruction has been emulated and result   #
+# saved, then we check to see if any enabled exceptions resulted from   #
+# instruction emulation. If none, then we exit through the "callout"    #
+# _fpsp_done(). If there is an enabled FP exception, then we insert     #
+# this exception into the FPU in the fsave state frame and then exit    #
+# through _fpsp_done().                                                 #
+#       PACKED opclass 0 and 2 is similar in how the instruction is     #
+# emulated and exceptions handled. The differences occur in how the     #
+# handler loads the packed op (by calling get_packed() routine) and     #
+# by the fact that a Trace exception could be pending for PACKED ops.   #
+# If a Trace exception is pending, then the current exception stack     #
+# frame is changed to a Trace exception stack frame and an exit is      #
+# made through _real_trace().                                           #
+#       For UNNORM/DENORM opclass 3, the actual move out to memory is   #
+# performed by calling the routine fout(). If no exception should occur #
+# as the result of emulation, then an exit either occurs through        #
+# _fpsp_done() or through _real_trace() if a Trace exception is pending #
+# (a Trace stack frame must be created here, too). If an FP exception   #
+# should occur, then we must create an exception stack frame of that    #
+# type and jump to either _real_snan(), _real_operr(), _real_inex(),    #
+# _real_unfl(), or _real_ovfl() as appropriate. PACKED opclass 3        #
+# emulation is performed in a similar manner.                           #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       This exception handles 3 types of operations:                   #
+# (1) FP Instructions using extended precision or packed immediate      #
+#     addressing mode.                                                  #
+# (2) The "fmovm.x" instruction w/ dynamic register specification.      #
+# (3) The "fmovm.l" instruction w/ 2 or 3 control registers.            #
+#                                                                       #
+#       For immediate data operations, the data is read in w/ a         #
+# _mem_read() "callout", converted to FP binary (if packed), and used   #
+# as the source operand to the instruction specified by the instruction #
+# word. If no FP exception should be reported ads a result of the       #
+# emulation, then the result is stored to the destination register and  #
+# the handler exits through _fpsp_done(). If an enabled exc has been    #
+# signalled as a result of emulation, then an fsave state frame         #
+# corresponding to the FP exception type must be entered into the 060   #
+# FPU before exiting. In either the enabled or disabled cases, we       #
+# must also check if a Trace exception is pending, in which case, we    #
+# must create a Trace exception stack frame from the current exception  #
+# stack frame. If no Trace is pending, we simply exit through           #
+# _fpsp_done().                                                         #
+#       For "fmovm.x", call the routine fmovm_dynamic() which will      #
+# decode and emulate the instruction. No FP exceptions can be pending   #
+# as a result of this operation emulation. A Trace exception can be     #
+# pending, though, which means the current stack frame must be changed  #
+# to a Trace stack frame and an exit made through _real_trace().        #
+# For the case of "fmovm.x Dn,-(a7)", where the offending instruction   #
+# was executed from supervisor mode, this handler must store the FP     #
+# register file values to the system stack by itself since              #
+# fmovm_dynamic() can't handle this. A normal exit is made through      #
+# fpsp_done().                                                          #
+#       For "fmovm.l", fmovm_ctrl() is used to emulate the instruction. #
+# Again, a Trace exception may be pending and an exit made through      #
+# _real_trace(). Else, a normal exit is made through _fpsp_done().      #
+#                                                                       #
+#       Before any of the above is attempted, it must be checked to     #
+# see if the FPU is disabled. Since the "Unimp <ea>" exception is taken #
+# before the "FPU disabled" exception, but the "FPU disabled" exception #
+# has higher priority, we check the disabled bit in the PCR. If set,    #
+# then we must create an 8 word "FPU disabled" exception stack frame    #
+# from the current 4 word exception stack frame. This includes          #
+# reproducing the effective address of the instruction to put on the    #
+# new stack frame.                                                      #
+#                                                                       #
+#       In the process of all emulation work, if a _mem_read()          #
+# "callout" returns a failing result indicating an access error, then   #
+# we must create an access error stack frame from the current stack     #
+# frame. This information includes a faulting address and a fault-      #
+# status-longword. These are created within this handler.               #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       In a system where the FP Operr exception is enabled, the goal   #
+# is to get to the handler specified at _real_operr(). But, on the 060, #
+# for opclass zero and two instruction taking this exception, the       #
+# input operand in the fsave frame may be incorrect for some cases      #
+# and needs to be corrected. This handler calls fix_skewed_ops() to     #
+# do just this and then exits through _real_operr().                    #
+#       For opclass 3 instructions, the 060 doesn't store the default   #
+# operr result out to memory or data register file as it should.        #
+# This code must emulate the move out before finally exiting through    #
+# _real_inex(). The move out, if to memory, is performed using          #
+# _mem_write() "callout" routines that may return a failing result.     #
+# In this special case, the handler must exit through facc_out()        #
+# which creates an access error stack frame from the current operr      #
+# stack frame.                                                          #

+#       - The system stack is unchanged                                 #
+#       - The fsave frame contains the adjusted src op for opclass 0,2  #
+#                                                                       #
+# ALGORITHM *********************************************************** #
+#       In a system where the FP SNAN exception is enabled, the goal    #
+# is to get to the handler specified at _real_snan(). But, on the 060,  #
+# for opclass zero and two instructions taking this exception, the      #
+# input operand in the fsave frame may be incorrect for some cases      #
+# and needs to be corrected. This handler calls fix_skewed_ops() to     #
+# do just this and then exits through _real_snan().                     #
+#       For opclass 3 instructions, the 060 doesn't store the default   #
+# SNAN result out to memory or data register file as it should.         #
+# This code must emulate the move out before finally exiting through    #
+# _real_snan(). The move out, if to memory, is performed using          #
+# _mem_write() "callout" routines that may return a failing result.     #
+# In this special case, the handler must exit through facc_out()        #
+# which creates an access error stack frame from the current SNAN       #
+# stack frame.                                                          #
+#       For the case of an extended precision opclass 3 instruction,    #
+# if the effective addressing mode was -() or ()+, then the address     #
+# register must get updated by calling _calc_ea_fout(). If the <ea>     #
+# was -(a7) from supervisor mode, then the exception frame currently    #
+# on the system stack must be carefully moved "down" to make room       #
+# for the operand being moved.                                          #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       In a system where the FP Inexact exception is enabled, the goal #
+# is to get to the handler specified at _real_inex(). But, on the 060,  #
+# for opclass zero and two instruction taking this exception, the       #
+# hardware doesn't store the correct result to the destination FP       #
+# register as did the '040 and '881/2. This handler must emulate the    #
+# instruction in order to get this value and then store it to the       #
+# correct register before calling _real_inex().                         #
+#       For opclass 3 instructions, the 060 doesn't store the default   #
+# inexact result out to memory or data register file as it should.      #
+# This code must emulate the move out by calling fout() before finally  #
+# exiting through _real_inex().                                         #
+#                                                                       #

+# ALGORITHM *********************************************************** #
+#       The effective address must be calculated since this is entered  #
+# from an "Unimplemented Effective Address" exception handler. So, we   #
+# have our own fcalc_ea() routine here. If an access error is flagged   #
+# by a _{i,d,}mem_read() call, we must exit through the special         #
+# handler.                                                              #
+#       The data register is determined and its value loaded to get the #
+# string of FP registers affected. This value is used as an index into  #
+# a lookup table such that we can determine the number of bytes         #
+# involved.                                                             #
+#       If the instruction is "fmovm.x <ea>,Dn", a _mem_read() is used  #
+# to read in all FP values. Again, _mem_read() may fail and require a   #
+# special exit.                                                         #
+#       If the instruction is "fmovm.x DN,<ea>", a _mem_write() is used #
+# to write all FP values. _mem_write() may also fail.                   #
+#       If the instruction is "fmovm.x DN,-(a7)" from supervisor mode,  #
+# then we return the size of the dump and the string to the caller      #
+# so that the move can occur outside of this routine. This special      #
+# case is required so that moves to the system stack are handled        #
+# correctly.                                                            #

+#       This routine is accessed by many handlers that need to do an    #
+# opclass three move of an operand out to memory.                       #
+#       Decode an fmove out (opclass 3) instruction to determine if     #
+# it's b,w,l,s,d,x, or p in size. b,w,l can be stored to either a data  #
+# register or memory. The algorithm uses a standard "fmove" to create   #
+# the rounded result. Also, since exceptions are disabled, this also    #
+# create the correct OPERR default result if appropriate.               #
+#       For sgl or dbl precision, overflow or underflow can occur. If   #
+# either occurs and is enabled, the EXOP.                               #
+#       For extended precision, the stacked <ea> must be fixed along    #
+# w/ the address index register as appropriate w/ _calc_ea_fout(). If   #
+# the source is a denorm and if underflow is enabled, an EXOP must be   #
+# created.                                                              #
+#       For packed, the k-factor must be fetched from the instruction   #
+# word or a data register. The <ea> must be fixed as w/ extended        #
+# precision. Then, bindec() is called to create the appropriate         #
+# packed result.                                                        #

+# and an actual fneg performed to see if overflow/underflow would have  #

+# scale the result exponent and return result. FPSR gets set based on   #

+#  2p.(positive exp)

+#   4. Subtract the count from the exp.

+#  *Why 27?  If the adjusted exponent is within -28 < expA < 28, than

+# ALGORITHM *********************************************************** #
+#       The 64-bit binary is assumed to have a decimal point before     #
+#       bit 63.  The fraction is multiplied by 10 using a mul by 2      #
+#       shift and a mul by 8 shift.  The bits shifted out of the        #
+#       msb form a decimal digit.  This process is iterated until       #
+#       LEN digits are formed.                                          #
+#                                                                       #
+# A1. Init d7 to 1.  D7 is the byte digit counter, and if 1, the        #
+#     digit formed will be assumed the least significant.  This is      #
+#     to force the first byte formed to have a 0 in the upper 4 bits.   #
+#                                                                       #
+# A2. Beginning of the loop:                                            #
+#     Copy the fraction in d2:d3 to d4:d5.                              #

+# A3. Multiply the fraction in d2:d3 by 8 using bit-field               #
+#     extracts and shifts.  The three msbs from d2 will go into d1.     #
+#                                                                       #
+# A4. Multiply the fraction in d4:d5 by 2 using shifts.  The msb        #
+#     will be collected by the carry.                                   #

+# A5. Add using the carry the 64-bit quantities in d2:d3 and d4:d5      #
+#     into d2:d3.  D1 will contain the bcd digit formed.                #

+# A6. Test d7.  If zero, the digit formed is the ms digit.  If non-     #
+#     zero, it is the ls digit.  Put the digit in its place in the      #
+#     upper word of d0.  If it is the ls digit, write the word          #

+/*
+ * Linux startup code.
+ *
+ * At this point, the boot loader has:
+ * Disabled interrupts
+ * Disabled caches
+ * Put us in supervisor state.
+ *
+ * The kernel setup code takes the following steps:
+ * .  Raise interrupt level
+ * .  Set up initial kernel memory mapping.
+ *    .  This sets up a mapping of the 4M of memory the kernel is located in.
+ *    .  It also does a mapping of any initial machine specific areas.
+ * .  Enable the MMU
+ * .  Enable cache memories
+ * .  Jump to kernel startup
+ *
+ * Much of the file restructuring was to accomplish:
+ * 1) Remove register dependency through-out the file.
+ * 2) Increase use of subroutines to perform functions
+ * 3) Increase readability of the code
+ *
+ * Of course, readability is a subjective issue, so it will never be
+ * argued that that goal was accomplished.  It was merely a goal.
+ * A key way to help make code more readable is to give good
+ * documentation.  So, the first thing you will find is exaustive
+ * write-ups on the structure of the file, and the features of the
+ * functional subroutines.
+ *
+ * General Structure:
+ * ------------------
+ *      Without a doubt the single largest chunk of head.S is spent
+ * mapping the kernel and I/O physical space into the logical range
+ * for the kernel.
+ *      There are new subroutines and data structures to make MMU
+ * support cleaner and easier to understand.
+ *      First, you will find a routine call "mmu_map" which maps
+ * a logical to a physical region for some length given a cache
+ * type on behalf of the caller.  This routine makes writing the
+ * actual per-machine specific code very simple.
+ *      A central part of the code, but not a subroutine in itself,
+ * is the mmu_init code which is broken down into mapping the kernel
+ * (the same for all machines) and mapping machine-specific I/O
+ * regions.
+ *      Also, there will be a description of engaging the MMU and
+ * caches.
+ *      You will notice that there is a chunk of code which
+ * can emit the entire MMU mapping of the machine.  This is present
+ * only in debug modes and can be very helpful.
+ *      Further, there is a new console driver in head.S that is
+ * also only engaged in debug mode.  Currently, it's only supported
+ * on the Macintosh class of machines.  However, it is hoped that
+ * others will plug-in support for specific machines.
+ *
+ * ######################################################################
+ *
+ * mmu_map
+ * -------
+ *      mmu_map was written for two key reasons.  First, it was clear
+ * that it was very difficult to read the previous code for mapping
+ * regions of memory.  Second, the Macintosh required such extensive
+ * memory allocations that it didn't make sense to propagate the
+ * existing code any further.
+ *      mmu_map requires some parameters:
+ *
+ *      mmu_map (logical, physical, length, cache_type)
+ *
+ *      While this essentially describes the function in the abstract, you'll
+ * find more indepth description of other parameters at the implementation site.
+ *
+ * mmu_get_root_table_entry
+ * ------------------------
+ * mmu_get_ptr_table_entry
+ * -----------------------
+ * mmu_get_page_table_entry
+ * ------------------------
+ *
+ *      These routines are used by other mmu routines to get a pointer into
+ * a table, if necessary a new table is allocated. These routines are working
+ * basically like pmd_alloc() and pte_alloc() in <asm/pgtable.h>. The root
+ * table needs of course only to be allocated once in mmu_get_root_table_entry,
+ * so that here also some mmu specific initialization is done. The second page
+ * at the start of the kernel (the first page is unmapped later) is used for
+ * the kernel_pg_dir. It must be at a position known at link time (as it's used
+ * to initialize the init task struct) and since it needs special cache
+ * settings, it's the easiest to use this page, the rest of the page is used
+ * for further pointer tables.
+ * mmu_get_page_table_entry allocates always a whole page for page tables, this
+ * means 1024 pages and so 4MB of memory can be mapped. It doesn't make sense
+ * to manage page tables in smaller pieces as nearly all mappings have that
+ * size.
+ *
+ * ######################################################################
+ *
+ *
+ * ######################################################################
+ *
+ * mmu_engage
+ * ----------
+ *      Thanks to a small helping routine enabling the mmu got quite simple
+ * and there is only one way left. mmu_engage makes a complete a new mapping
+ * that only includes the absolute necessary to be able to jump to the final
+ * postion and to restore the original mapping.
+ * As this code doesn't need a transparent translation register anymore this
+ * means all registers are free to be used by machines that needs them for
+ * other purposes.
+ *
+ * ######################################################################
+ *
+ * mmu_print
+ * ---------
+ *      This algorithm will print out the page tables of the system as
+ * appropriate for an 030 or an 040.  This is useful for debugging purposes
+ * and as such is enclosed in #ifdef MMU_PRINT/#endif clauses.
+ *
+ * ######################################################################
+ *
+ * console_init
+ * ------------
+ *      The console is also able to be turned off.  The console in head.S
+ * is specifically for debugging and can be very useful.  It is surrounded by
+ * #ifdef CONSOLE/#endif clauses so it doesn't have to ship in known-good
+ * kernels.  It's basic algorithm is to determine the size of the screen
+ * (in height/width and bit depth) and then use that information for
+ * displaying an 8x8 font or an 8x16 (widthxheight).  I prefer the 8x8 for
+ * debugging so I can see more good data.  But it was trivial to add support
+ * for both fonts, so I included it.
+ *      Also, the algorithm for plotting pixels is abstracted so that in
+ * theory other platforms could add support for different kinds of frame
+ * buffers.  This could be very useful.
+ *
+ * console_put_penguin
+ * -------------------
+ *      An important part of any Linux bring up is the penguin and there's
+ * nothing like getting the Penguin on the screen!  This algorithm will work
+ * on any machine for which there is a console_plot_pixel.
+ *
+ * console_scroll
+ * --------------
+ *      My hope is that the scroll algorithm does the right thing on the
+ * various platforms, but it wouldn't be hard to add the test conditions
+ * and new code if it doesn't.
+ *
+ * console_putc
+ * -------------
+ *
+ * ######################################################################
+ *
+ *      Register usage has greatly simplified within head.S. Every subroutine
+ * saves and restores all registers that it modifies (except it returns a
+ * value in there of course). So the only register that needs to be initialized
+ * is the stack pointer.
+ * All other init code and data is now placed in the init section, so it will
+ * be automatically freed at the end of the kernel initialization.

+ *
+ * options
+ * -------
+ *      There are many options available in a build of this file.  I've
+ * taken the time to describe them here to save you the time of searching
+ * for them and trying to understand what they mean.
+ *
+ * CONFIG_xxx:  These are the obvious machine configuration defines created
+ * during configuration.  These are defined in include/linux/autoconf.h.
+ *
+ * CONSOLE:     There is support for head.S console in this file.  This
+ * console can talk to a Mac frame buffer, but could easily be extrapolated
+ * to extend it to support other platforms.
+ *
+ * TEST_MMU:    This is a test harness for running on any given machine but
+ * getting an MMU dump for another class of machine.  The classes of machines
+ * that can be tested are any of the makes (Atari, Amiga, Mac, VME, etc.)
+ * and any of the models (030, 040, 060, etc.).
+ *
+ *      NOTE:   TEST_MMU is NOT permanent!  It is scheduled to be removed
+ *              When head.S boots on Atari, Amiga, Macintosh, and VME
+ *              machines.  At that point the underlying logic will be
+ *              believed to be solid enough to be trusted, and TEST_MMU
+ *              can be dropped.  Do note that that will clean up the
+ *              head.S code significantly as large blocks of #if/#else
+ *              clauses can be removed.
+ *
+ * MMU_NOCACHE_KERNEL:  On the Macintosh platform there was an inquiry into
+ * determing why devices don't appear to work.  A test case was to remove
+ * the cacheability of the kernel bits.
+ *
+ * MMU_PRINT:   There is a routine built into head.S that can display the
+ * MMU data structures.  It outputs its result through the serial_putc
+ * interface.  So where ever that winds up driving data, that's where the
+ * mmu struct will appear.  On the Macintosh that's typically the console.
+ *
+ * SERIAL_DEBUG:        There are a series of putc() macro statements
+ * scattered through out the code to give progress of status to the
+ * person sitting at the console.  This constant determines whether those
+ * are used.
+ *
+ * DEBUG:       This is the standard DEBUG flag that can be set for building
+ *              the kernel.  It has the effect adding additional tests into
+ *              the code.
+ *
+ * FONT_6x11:
+ * FONT_8x8:
+ * FONT_8x16:
+ *              In theory these could be determined at run time or handed
+ *              over by the booter.  But, let's be real, it's a fine hard
+ *              coded value.  (But, you will notice the code is run-time
+ *              flexible!)  A pointer to the font's struct font_desc
+ *              is kept locally in Lconsole_font.  It is used to determine
+ *              font size information dynamically.
+ *
+ * Atari constants:
+ * USE_PRINTER: Use the printer port for serial debug.
+ * USE_SCC_B:   Use the SCC port A (Serial2) for serial debug.
+ * USE_SCC_A:   Use the SCC port B (Modem2) for serial debug.
+ * USE_MFP:     Use the ST-MFP port (Modem1) for serial debug.
+ *
+ * Macintosh constants:
+ * MAC_SERIAL_DEBUG:    Turns on serial debug output for the Macintosh.
+ * MAC_USE_SCC_A:       Use the SCC port A (modem) for serial debug.
+ * MAC_USE_SCC_B:       Use the SCC port B (printer) for serial debug (default).

+ *
+ * Map the kernel (that's already done),

+ * as absolutely (this requirement mostly stems from
+ * the fact that when the frame buffer is at
+ * 0x0000.0000 then we know there is valid RAM just
+ * above the screen that we don't want to waste!).
+ *
+ * By the way, if the frame buffer is at 0x0000.0000
+ * then the Macintosh is known as an RBV based Mac.
+ *
+ * By the way 2, the code currently maps in a bunch of
+ * regions.  But I'd like to cut that out.  (And move most
+ * of the mappings up into the kernel proper ... or only
+ * map what's necessary.)

+ * mmu_engage
+ *
+ * This chunk of code performs the gruesome task of engaging the MMU.
+ * The reason its gruesome is because when the MMU becomes engaged it
+ * maps logical addresses to physical addresses.  The Program Counter
+ * register is then passed through the MMU before the next instruction
+ * is fetched (the instruction following the engage MMU instruction).
+ * This may mean one of two things:
+ * 1. The Program Counter falls within the logical address space of
+ *    the kernel of which there are two sub-possibilities:
+ *    A. The PC maps to the correct instruction (logical PC == physical
+ *       code location), or
+ *    B. The PC does not map through and the processor will read some
+ *       data (or instruction) which is not the logically next instr.
+ *    As you can imagine, A is good and B is bad.
+ * Alternatively,
+ * 2. The Program Counter does not map through the MMU.  The processor
+ *    will take a Bus Error.
+ * Clearly, 2 is bad.
+ * It doesn't take a wiz kid to figure you want 1.A.
+ * This code creates that possibility.
+ * There are two possible 1.A. states (we now ignore the other above states):
+ * A. The kernel is located at physical memory addressed the same as
+ *    the logical memory for the kernel, i.e., 0x01000.
+ * B. The kernel is located some where else.  e.g., 0x0400.0000
+ *
+ *    Under some conditions the Macintosh can look like A or B.
+ * [A friend and I once noted that Apple hardware engineers should be
+ * wacked twice each day: once when they show up at work (as in, Whack!,
+ * "This is for the screwy hardware we know you're going to design today."),
+ * and also at the end of the day (as in, Whack! "I don't know what
+ * you designed today, but I'm sure it wasn't good."). -- rst]
+ *
+ * This code works on the following premise:
+ * If the kernel start (%d5) is within the first 16 Meg of RAM,
+ * then create a mapping for the kernel at logical 0x8000.0000 to
+ * the physical location of the pc.  And, create a transparent
+ * translation register for the first 16 Meg.  Then, after the MMU
+ * is engaged, the PC can be moved up into the 0x8000.0000 range
+ * and then the transparent translation can be turned off and then
+ * the PC can jump to the correct logical location and it will be
+ * home (finally).  This is essentially the code that the Amiga used
+ * to use.  Now, it's generalized for all processors.  Which means
+ * that a fresh (but temporary) mapping has to be created.  The mapping
+ * is made in page 0 (an as of yet unused location -- except for the
+ * stack!).  This temporary mapping will only require 1 pointer table
+ * and a single page table (it can map 256K).
+ *
+ * OK, alternatively, imagine that the Program Counter is not within
+ * the first 16 Meg.  Then, just use Transparent Translation registers
+ * to do the right thing.
+ *
+ * Last, if _start is already at 0x01000, then there's nothing special
+ * to do (in other words, in a degenerate case of the first case above,
+ * do nothing).
+ *
+ * Let's do it.

+ *      MMU Initialization Begins Here
+ *
+ *      The structure of the MMU tables on the 68k machines
+ *      is thus:
+ *      Root Table
+ *              Logical addresses are translated through
+ *      a hierarchical translation mechanism where the high-order
+ *      seven bits of the logical address (LA) are used as an
+ *      index into the "root table."  Each entry in the root
+ *      table has a bit which specifies if it's a valid pointer to a
+ *      pointer table.  Each entry defines a 32KMeg range of memory.
+ *      If an entry is invalid then that logical range of 32M is
+ *      invalid and references to that range of memory (when the MMU
+ *      is enabled) will fault.  If the entry is valid, then it does
+ *      one of two things.  On 040/060 class machines, it points to
+ *      a pointer table which then describes more finely the memory
+ *      within that 32M range.  On 020/030 class machines, a technique
+ *      called "early terminating descriptors" are used.  This technique
+ *      allows an entire 32Meg to be described by a single entry in the
+ *      root table.  Thus, this entry in the root table, contains the
+ *      physical address of the memory or I/O at the logical address
+ *      which the entry represents and it also contains the necessary
+ *      cache bits for this region.
+ *
+ *      Pointer Tables
+ *              Per the Root Table, there will be one or more
+ *      pointer tables.  Each pointer table defines a 32M range.
+ *      Not all of the 32M range need be defined.  Again, the next
+ *      seven bits of the logical address are used an index into
+ *      the pointer table to point to page tables (if the pointer
+ *      is valid).  There will undoubtedly be more than one
+ *      pointer table for the kernel because each pointer table
+ *      defines a range of only 32M.  Valid pointer table entries
+ *      point to page tables, or are early terminating entries
+ *      themselves.
+ *
+ *      Page Tables
+ *              Per the Pointer Tables, each page table entry points
+ *      to the physical page in memory that supports the logical
+ *      address that translates to the particular index.
+ *
+ *      In short, the Logical Address gets translated as follows:
+ *              bits 31..26 - index into the Root Table
+ *              bits 25..18 - index into the Pointer Table
+ *              bits 17..12 - index into the Page Table
+ *              bits 11..0  - offset into a particular 4K page
+ *
+ *      The algorithms which follows do one thing: they abstract
+ *      the MMU hardware.  For example, there are three kinds of
+ *      cache settings that are relevant.  Either, memory is
+ *      being mapped in which case it is either Kernel Code (or
+ *      the RamDisk) or it is MMU data.  On the 030, the MMU data
+ *      option also describes the kernel.  Or, I/O is being mapped
+ *      in which case it has its own kind of cache bits.  There
+ *      are constants which abstract these notions from the code that
+ *      actually makes the call to map some range of memory.

+ * 11/07/96: Changed all add_/remove_isr() to request_/free_irq() calls.
+ *           Removed irq list support, if any machine needs an irq server
+ *           it must implement this itself (as it's already done), instead
+ *           only default handler are used with mach_default_handler.
+ *           request_irq got some flags different from other architectures:
+ *           - IRQ_FLG_REPLACE : Replace an existing handler (the default one
+ *                               can be replaced without this flag)
+ *           - IRQ_FLG_LOCK : handler can't be replaced
+ *           There are other machine depending flags, see there
+ *           If you want to replace a default handler you should know what
+ *           you're doing, since it might handle different other irq sources
+ *           which must be served                               /Roman Zippel

+ * wake up and exit.  ALL waiting processes actually wake up but
+ * only the one that gets to the "waking" field first will gate
+ * through and acquire the semaphore.  The others will go back
+ * to sleep.
+ *
+ * Note that these functions are only called when there is

+ * INET         An implementation of the TCP/IP protocol suite for the LINUX

+ * 03/02/96     Jes Sorensen, Andreas Schwab, Roman Hodek:
+ *              Fixed some nasty bugs, causing some horrible crashes.
+ *              A: At some points, the sum (%0) was used as
+ *              length-counter instead of the length counter
+ *              (%1). Thanks to Roman Hodek for pointing this out.
+ *              B: GCC seems to mess up if one uses too many
+ *              data-registers to hold input values and one tries to
+ *              specify d0 and d1 as scratch registers. Letting gcc
+ *              choose these registers itself solves the problem.

+ * The IOP chips are used in the IIfx and some Quadras (900, 950) to manage
+ * serial and ADB. They are actually a 6502 processor and some glue logic.
+ *
+ * 990429 (jmt) - Initial implementation, just enough to knock the SCC IOP
+ *                into compatible mode so nobody has to fiddle with the
+ *                Serial Switch control panel anymore.
+ * 990603 (jmt) - Added code to grab the correct ISM IOP interrupt for OSS
+ *                and non-OSS machines (at least I hope it's correct on a
+ *                non-OSS machine -- someone with a Q900 or Q950 needs to
+ *                check this.)
+ * 990605 (jmt) - Rearranged things a bit wrt IOP detection; iop_present is
+ *                gone, IOP base addresses are now in an array and the
+ *                globally-visible functions take an IOP number instead of an
+ *                an actual base address.
+ * 990610 (jmt) - Finished the message passing framework and it seems to work.
+ *                Sending _definitely_ works; my adb-bus.c mods can send
+ *                messages and receive the MSG_COMPLETED status back from the
+ *                IOP. The trick now is figuring out the message formats.
+ * 990611 (jmt) - More cleanups. Fixed problem where unclaimed messages on a
+ *                receive channel were never properly acknowledged. Bracketed
+ *                the remaining debug printk's with #ifdef's and disabled
+ *                debugging. I can now type on the console.
+ * 990612 (jmt) - Copyright notice added. Reworked the way replies are handled.
+ *                It turns out that replies are placed back in the send buffer
+ *                for that channel; messages on the receive channels are always
+ *                unsolicited messages from the IOP (and our replies to them
+ *                should go back in the receive channel.) Also added tracking
+ *                of device names to the listener functions ala the interrupt
+ *                handlers.
+ * 990729 (jmt) - Added passing of pt_regs structure to IOP handlers. This is
+ *                used by the new unified ADB driver.
+ *
+ * TODO:
+ *
+ * o Something should be periodically checking iop_alive() to make sure the
+ *   IOP hasn't died.
+ * o Some of the IOP manager routines need better error checking and
+ *   return codes. Nothing major, just prettying up.

+/*
+ * -----------------------
+ * IOP Message Passing 101
+ * -----------------------
+ *
+ * The host talks to the IOPs using a rather simple message-passing scheme via
+ * a shared memory area in the IOP RAM. Each IOP has seven "channels"; each
+ * channel is conneced to a specific software driver on the IOP. For example
+ * on the SCC IOP there is one channel for each serial port. Each channel has
+ * an incoming and and outgoing message queue with a depth of one.
+ *
+ * A message is 32 bytes plus a state byte for the channel (MSG_IDLE, MSG_NEW,
+ * MSG_RCVD, MSG_COMPLETE). To send a message you copy the message into the
+ * buffer, set the state to MSG_NEW and signal the IOP by setting the IRQ flag
+ * in the IOP control to 1. The IOP will move the state to MSG_RCVD when it
+ * receives the message and then to MSG_COMPLETE when the message processing
+ * has completed. It is the host's responsibility at that point to read the
+ * reply back out of the send channel buffer and reset the channel state back
+ * to MSG_IDLE.
+ *
+ * To receive message from the IOP the same procedure is used except the roles
+ * are reversed. That is, the IOP puts message in the channel with a state of
+ * MSG_NEW, and the host receives the message and move its state to MSG_RCVD
+ * and then to MSG_COMPLETE when processing is completed and the reply (if any)
+ * has been placed back in the receive channel. The IOP will then reset the
+ * channel state to MSG_IDLE.
+ *
+ * Two sets of host interrupts are provided, INT0 and INT1. Both appear on one
+ * interrupt level; they are distinguished by a pair of bits in the IOP status
+ * register. The IOP will raise INT0 when one or more messages in the send
+ * channels have gone to the MSG_COMPLETE state and it will raise INT1 when one
+ * or more messages on the receive channels have gone to the MSG_NEW state.
+ *
+ * Since each channel handles only one message we have to implement a small
+ * interrupt-driven queue on our end. Messages to be sent are placed on the
+ * queue for sending and contain a pointer to an optional callback function.
+ * The handler for a message is called when the message state goes to
+ * MSG_COMPLETE.
+ *
+ * For receiving message we maintain a list of handler functions to call when
+ * a message is received on that IOP/channel combination. The handlers are
+ * called much like an interrupt handler and are passed a copy of the message
+ * from the IOP. The message state will be in MSG_RCVD while the handler runs;
+ * it is the handler's responsibility to call iop_complete_message() when
+ * finished; this function moves the message state to MSG_COMPLETE and signals
+ * the IOP. This two-step process is provided to allow the handler to defer
+ * message processing to a bottom-half handler if the processing will take
+ * a signifigant amount of time (handlers are called at interrupt time so they
+ * should execute quickly.)

+ *      Macintosh interrupts
+ *
+ * General design:
+ * In contrary to the Amiga and Atari platforms, the Mac hardware seems to
+ * exclusively use the autovector interrupts (the 'generic level0-level7'
+ * interrupts with exception vectors 0x19-0x1f). The following interrupt levels
+ * are used:
+ *      1       - VIA1
+ *                - slot 0: one second interrupt (CA2)
+ *                - slot 1: VBlank (CA1)
+ *                - slot 2: ADB data ready (SR full)
+ *                - slot 3: ADB data  (CB2)
+ *                - slot 4: ADB clock (CB1)
+ *                - slot 5: timer 2
+ *                - slot 6: timer 1
+ *                - slot 7: status of IRQ; signals 'any enabled int.'
+ *
+ *      2       - VIA2 or RBV
+ *                - slot 0: SCSI DRQ (CA2)
+ *                - slot 1: NUBUS IRQ (CA1) need to read port A to find which
+ *                - slot 2: /EXP IRQ (only on IIci)
+ *                - slot 3: SCSI IRQ (CB2)
+ *                - slot 4: ASC IRQ (CB1)
+ *                - slot 5: timer 2 (not on IIci)
+ *                - slot 6: timer 1 (not on IIci)
+ *                - slot 7: status of IRQ; signals 'any enabled int.'
+ *
+ *      2       - OSS (IIfx only?)
+ *                - slot 0: SCSI interrupt
+ *                - slot 1: Sound interrupt
+ *
+ * Levels 3-6 vary by machine type. For VIA or RBV Macintoshes:
+ *
+ *      3       - unused (?)
+ *
+ *      4       - SCC (slot number determined by reading RR3 on the SSC itself)
+ *                - slot 1: SCC channel A
+ *                - slot 2: SCC channel B
+ *
+ *      5       - unused (?)
+ *                [serial errors or special conditions seem to raise level 6
+ *                interrupts on some models (LC4xx?)]
+ *
+ *      6       - off switch (?)
+ *
+ * For OSS Macintoshes (IIfx only at this point):
+ *
+ *      3       - Nubus interrupt
+ *                - slot 0: Slot $9
+ *                - slot 1: Slot $A
+ *                - slot 2: Slot $B
+ *                - slot 3: Slot $C
+ *                - slot 4: Slot $D
+ *                - slot 5: Slot $E
+ *
+ *      4       - SCC IOP
+ *                - slot 1: SCC channel A
+ *                - slot 2: SCC channel B
+ *
+ *      5       - ISM IOP (ADB?)
+ *
+ *      6       - unused
+ *
+ * For PSC Macintoshes (660AV, 840AV):
+ *
+ *      3       - PSC level 3
+ *                - slot 0: MACE
+ *
+ *      4       - PSC level 4
+ *                - slot 1: SCC channel A interrupt
+ *                - slot 2: SCC channel B interrupt
+ *                - slot 3: MACE DMA
+ *
+ *      5       - PSC level 5
+ *
+ *      6       - PSC level 6
+ *
+ * Finally we have good 'ole level 7, the non-maskable interrupt:
+ *
+ *      7       - NMI (programmer's switch on the back of some Macs)
+ *                Also RAM parity error on models which support it (IIc, IIfx?)
+ *
+ * The current interrupt logic looks something like this:
+ *
+ * - We install dispatchers for the autovector interrupts (1-7). These
+ *   dispatchers are responsible for querying the hardware (the
+ *   VIA/RBV/OSS/PSC chips) to determine the actual interrupt source. Using
+ *   this information a machspec interrupt number is generated by placing the
+ *   index of the interrupt hardware into the low three bits and the original
+ *   autovector interrupt number in the upper 5 bits. The handlers for the
+ *   resulting machspec interrupt are then called.
+ *
+ * - Nubus is a special case because its interrupts are hidden behind two
+ *   layers of hardware. Nubus interrupts come in as index 1 on VIA #2,
+ *   which translates to IRQ number 17. In this spot we install _another_
+ *   dispatcher. This dispatcher finds the interrupting slot number (9-F) and
+ *   then forms a new machspec interrupt number as above with the slot number
+ *   minus 9 in the low three bits and the pseudo-level 7 in the upper five
+ *   bits.  The handlers for this new machspec interrupt number are then
+ *   called. This puts Nubus interrupts into the range 56-62.
+ *
+ * - The Baboon interrupts (used on some PowerBooks) are an even more special
+ *   case. They're hidden behind the Nubus slot $C interrupt thus adding a
+ *   third layer of indirection. Why oh why did the Apple engineers do that?
+ *
+ * - We support "fast" and "slow" handlers, just like the Amiga port. The
+ *   fast handlers are called first and with all interrupts disabled. They
+ *   are expected to execute quickly (hence the name). The slow handlers are
+ *   called last with interrupts enabled and the interrupt level restored.
+ *   They must therefore be reentrant.
+ *
+ *   TODO:

+ *
+ *      This chip is used in the IIfx in place of VIA #2. It acts like a fancy
+ *      VIA chip with prorammable interrupt levels.
+ *
+ * 990502 (jmt) - Major rewrite for new interrupt architecture as well as some
+ *                recent insights into OSS operational details.
+ * 990610 (jmt) - Now taking fulll advantage of the OSS. Interrupts are mapped
+ *                to mostly match the A/UX interrupt scheme supported on the
+ *                VIA side. Also added support for enabling the ISM irq again
+ *                since we now have a functional IOP manager.

+Linux for the Q40
+=================
+
+You may try http://www.geocities.com/SiliconValley/Bay/2602/ for
+some up to date information. Booter and other tools will be also
+available from this place or ftp.uni-erlangen.de/linux/680x0/q40/
+and mirrors.
+
+Hints to documentation usually refer to the linux source tree in
+/usr/src/linux/Documentation unless URL given.
+
+It seems IRQ unmasking can't be safely done on a Q40. IRQ probing
+is not implemented - do not try it! (See below)
+
+For a list of kernel command-line options read the documentation for the
+particular device drivers.
+
+The floppy imposes a very high interrupt load on the CPU, approx 30K/s.
+When something blocks interrupts (HD) it will lose some of them, so far
+this is not known to have caused any data loss. On highly loaded systems
+it can make the floppy very slow or practically stop. Other Q40 OS' simply
+poll the floppy for this reason - something that can't be done in Linux.
+Only possible cure is getting a 82072 controller with fifo instead of
+the 8272A.
+
+drivers used by the Q40, apart from the very obvious (console etc.):
+        drivers/char/q40_keyb.c         # use PC keymaps for national keyboards
+                     serial.c           # normal PC driver - any speed
+                     lp.c               # printer driver
+                     genrtc.c           # RTC
+                char/joystick/*         # most of this should work, not
+                                        # in default config.in
+                block/q40ide.c          # startup for ide
+                      ide*              # see Documentation/ide.txt
+                      floppy.c          # normal PC driver, DMA emu in asm/floppy.h
+                                        # and arch/m68k/kernel/entry.S
+                                        # see drivers/block/README.fd
+                net/ne.c
+                video/q40fb.c
+                parport/*
+                sound/dmasound_core.c
+                      dmasound_q40.c
+
+Various other PC drivers can be enabled simply by adding them to
+arch/m68k/config.in, especially 8 bit devices should be without any
+problems. For cards using 16bit io/mem more care is required, like
+checking byte order issues, hacking memcpy_*_io etc.
+
+
+Debugging
+=========
+
+Upon startup the kernel will usually output "ABCQGHIJ" into the SRAM,
+preceded by the booter signature. This is a trace just in case something
+went wrong during earliest setup stages of head.S.
+**Changed** to preserve SRAM contents by default, this is only done when
+requested - SRAM must start with '%LX$' signature to do this. '-d' option
+to 'lxx' loader enables this.
+
+SRAM can also be used as additional console device, use debug=mem.
+This will save kernel startup msgs into SRAM, the screen will display
+only the penguin - and shell prompt if it gets that far..
+Unfortunately only 2000 bytes are available.
+
+Serial console works and can also be used for debugging, see loader_txt
+
+Most problems seem to be caused by fawlty or badly configured io-cards or
+hard drives anyway.
+Make sure to configure the parallel port as SPP and remove IRQ/DMA jumpers
+for first testing. The Q40 does not support DMA and may have trouble with
+parallel ports version of interrupts.
+
+
+Q40 Hardware Description
+========================
+
+This is just an overview, see asm-m68k/* for details ask if you have any
+questions.
+
+The Q40 consists of a 68040@40 MHz, 1MB video RAM, up to 32MB RAM, AT-style
+keyboard interface, 1 Programmable LED, 2x8bit DACs and up to 1MB ROM, 1MB
+shadow ROM.
+The Q60 has any of 68060 or 68LC060 and up to 128 MB RAM.
+
+Most interfacing like floppy, IDE, serial and parallel ports is done via ISA
+slots. The ISA io and mem range is mapped (sparse&byteswapped!) into separate
+regions of the memory.
+The main interrupt register IIRQ_REG will indicate whether an IRQ was internal
+or from some ISA devices, EIRQ_REG can distinguish up to 8 ISA IRQs.
+
+The Q40 custom chip is programmable to provide 2 periodic timers:
+        - 50 or 200 Hz - level 2, !!THIS CANT BE DISABLED!!
+        - 10 or 20 KHz - level 4, used for dma-sound
+
+Linux uses the 200 Hz interrupt for timer and beep by default.
+
+
+Interrupts
+==========
+
+q40 master chip handles only a subset of level triggered interrupts.
+
+Linux has some requirements wrt interrupt architecture, these are
+to my knowledge:
+        (a) interrupt handler must not be reentered even when sti() is called
+            from within handler
+        (b) working enable/disable_irq
+
+Luckily these requirements are only important for drivers shared
+with other architectures - ide,serial,parallel, ethernet.
+q40ints.c now contains a trivial hack for (a), (b) is more difficult
+because only irq's 4-15 can be disabled - and only all of them at once.
+Thus disable_irq() can effectively block the machine if the driver goes
+asleep.
+One thing to keep in mind when hacking around the interrupt code is
+that there is no way to find out which IRQ caused a request, [EI]IRQ_REG
+displays current state of the various IRQ lines.
+
+Keyboard
+========
+
+q40 receives AT make/break codes from the keyboard, these are translated to
+the PC scancodes x86 Linux uses. So by theory every national keyboard should
+work just by loading the appropriate x86 keytable - see any national-HOWTO.
+
+Unfortunately the AT->PC translation isn't quite trivial and even worse, my
+documentation of it is absolutely minimal - thus some exotic keys may not
+behave exactly as expected.
+
+There is still hope that it can be fixed completely though. If you encounter
+problems, email me ideally this:
+        - exact keypress/release sequence
+        - 'showkey -s' run on q40, non-X session
+        - 'showkey -s' run on a PC, non-X session
+        - AT codes as displayed by the q40 debugging ROM
+btw if the showkey output from PC and Q40 doesn't differ then you have some
+classic configuration problem - don't send me anything in this case
