This is fine, but please could you:

  1) Supply ChangeLogs for each subdirectory (ie bfd, gas, 
include/opcode, opcodes) detailing what the patch does there.

  2) Fix up the formatting in the comments to follow the GNU coding 
standard.

  3) Supply a test case to be added to gas/testsuites/gas/m68k/ to test 
the new instructions.

  4) Add a patch to the gas/NEWS file mentioning the support for the new 
instructions.

Thanks very much.

Cheers
  Nick
