27: This directory contains mpn functions for various m68k family chips.

30: CODE ORGANIZATION
31:
32: m68k m68000, m68010
33: m68k/mc68020 m68020 and up, including CPU32
34:
35:
36: The m5200 "coldfire", which is m68000 less a few instructions, currently has
37: no assembler code support.

39:
40: ASM FILES
41:
42: The .asm files are put through m4 for macro processing, and with the help of
43: configure give either MIT or Motorola syntax. The generic mpn/asm-defs.m4
44: is used, together with mpn/m68k/m68k-defs.m4. See comments in those files.
45:
46: Not all possible syntax variations are covered. GCC config/m68k for
47: instance has things like $ for immediates on CRDS or reversed cmp order for
48: AT&T SGS. These could probably be handled if anyone really needs it.
