I shouldn't make any last-minute changes just to make it easier > to add a proper ChangeLog entry. M'kay. Hope you don't mind that I sneaked in a few more register numbers. I'll submit a patch shortly to use these in the various mips*-tdep.c files such that we can remove the old #defines from tm-mips.h. Cheers, Mark Index: ChangeLog from Mark Kettenis * mips-tdep.h: Add MIPS_ZERO_REGNUM, MIPS_AT_REGNUM, MIPS_V0_REGNUM. MIPS_A0_REGNUM, MIPS_T9_REGNUM and MIPS_RA_REGNUM to enum with register numbers. (enum mips_insn_size): New enum.
