-
-   1) umul_ppmm(high_prod, low_prod, multipler, multiplicand)
-   multiplies two u32 integers MULTIPLER and MULTIPLICAND,
-   and generates a two-part u32 product in HIGH_PROD and
-   LOW_PROD.
-
-   2) __umulsidi3(a,b) multiplies two u32 integers A and B,
-   and returns a u64 product.  This is just a variant of umul_ppmm.
-
-   3) udiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator) divides a two-word unsigned integer, composed by the
-   integers HIGH_NUMERATOR and LOW_NUMERATOR, by DENOMINATOR and
-   places the quotient in QUOTIENT and the remainder in REMAINDER.
-   HIGH_NUMERATOR must be less than DENOMINATOR for correct operation.
-   If, in addition, the most significant bit of DENOMINATOR must be 1,
-   then the pre-processor symbol UDIV_NEEDS_NORMALIZATION is defined to 1.
-
-   4) sdiv_qrnnd(quotient, remainder, high_numerator, low_numerator,
-   denominator).  Like udiv_qrnnd but the numbers are signed.  The
-   quotient is rounded towards 0.
-
-   5) count_leading_zeros(count, x) counts the number of zero-bits from
-   the msb to the first non-zero bit.  This is the number of steps X
-   needs to be shifted left to set the msb.  Undefined for X == 0.
-
-   6) add_ssaaaa(high_sum, low_sum, high_addend_1, low_addend_1,
-   high_addend_2, low_addend_2) adds two two-word unsigned integers,
-   composed by HIGH_ADDEND_1 and LOW_ADDEND_1, and HIGH_ADDEND_2 and
-   LOW_ADDEND_2 respectively.  The result is placed in HIGH_SUM and
-   LOW_SUM.  Overflow (i.e. carry out) is not stored anywhere, and is
-   lost.
-
-   7) sub_ddmmss(high_difference, low_difference, high_minuend,
-   low_minuend, high_subtrahend, low_subtrahend) subtracts two
-   two-word unsigned integers, composed by HIGH_MINUEND_1 and
-   LOW_MINUEND_1, and HIGH_SUBTRAHEND_2 and LOW_SUBTRAHEND_2
-   respectively.  The result is placed in HIGH_DIFFERENCE and
-   LOW_DIFFERENCE.  Overflow (i.e. carry out) is not stored anywhere,
-   and is lost.
-
-   If any of these macros are left undefined for a particular CPU,
-   C macros are used.  */
