I considering asking for approval on this patch, but decided that the addition of the constant and string were obvious. The mips_gdbarch_init() changes probably aren't obvious, but I think they're safe in the sense that they won't break support for other MIPS ABIs. (I have some other patches on the way that I will ask approval for though.) * mips-tdep.c (enum mips_abi): Add MIPS_ABI_N64. (mips_abi_strings): Add "n64". (mips_gdbarch_init): Add test for n64 abi. Add MIPS_ABI_N64 case.
