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 ;-).
Index: ChangeLog
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.
