   Hi Andrew,

   This adds some symbolic constants to mips-tdep.h that I'd like to use
   to implement OpenBSD/mips64 signal trampoline support.

   OK?

Argh!  I shouldn't make any last-minute changes just to make it easier
to add a proper ChangeLog entry.

Here's a better patch.  It even compiler ;-).

from  Mark Kettenis  <kettenis@gnu.org>

	* mips-tdep.h: Add MIPS_ZERO_REGNUM, MIPS_AT_REGNUM and
	MIPS_RA_REGNUM to enum with register numbers.
	(enum mips_insn_size): New enum.
