+ * mips-tdep.c (mips_register_type): Simplify. Eliminate reference
+ to MIPS_REGISTER_TYPE. Make integer registers signed. Make IRIX
+ n32 registers 64 bit.
+ (mips_register_raw_size, mips_register_byte): For pseudo
+ registers, use the register's pseudo size and not the
+ corresponding raw register's size.
+ * config/mips/tm-mips64.h (MIPS_REGISTER_TYPE): Delete macro.
+ * config/mips/tm-mips.h (MIPS_REGISTER_TYPE): Delete macro.
+ * config/mips/tm-irix6.h: Don't #undef MIPS_REGISTER_TYPE.
