+/* Core file format: The core file is written in such a way that gdb
+ * can understand it and provide useful information to the user (under
+ * linux we use the 'trad-core' bfd).  There are quite a number of
+ * obstacles to being able to view the contents of the floating point
+ * registers, and until these are solved you will not be able to view
+ * the contents of them.  Actually, you can read in the core file and
+ * look at the contents of the user struct to find out what the
+ * floating point registers contain.
+ *
+ * The actual file contents are as follows:
+ * UPAGE:
+ *   1 page consisting of a user struct that tells gdb what is present
+ *   in the file.  Directly after this is a copy of the task_struct,
+ *   which is currently not used by gdb, but it may come in useful at
+ *   some point.  All of the registers are stored as part of the
+ *   upage.  The upage should always be only one page.
+ *
+ * DATA:
+ *   The data area is stored.  We use current->end_text to
+ *   current->brk to pick up all of the user variables, plus any
+ *   memory that may have been malloced.  No attempt is made to
+ *   determine if a page is demand-zero or if a page is totally
+ *   unused, we just cover the entire range.  All of the addresses are
+ *   rounded in such a way that an integral number of pages is
+ *   written.
+ *
+ * STACK:
+ *   We need the stack information in order to get a meaningful
+ *   backtrace.  We need to write the data from (esp) to
+ *   current->start_stack, so we round each of these off in order to
+ *   be able to write an integer number of pages.  The minimum core
+ *   file size is 3 pages, or 12288 bytes.

+ * MMU exception handler has different handling compare to no MMU kernel.
+ * Exception handler use jump table for directing of what happen. For MMU kernel

+ * 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.
