* config/mips/mips.h (mips_dwarf_regno): Declare.
(DBX_REGISTER_NUMBER): Remove redundant brackets.
(HI_REGNUM, LO_REGNUM): Define in an endian-dependent way.
(AC1HI_REGNUM, AC1LO_REGNUM, AC2HI_REGNUM, AC2LO_REGNUM)
(AC3HI_REGNUM, AC3LO_REGNUM, ACC_HI_REG_P): Delete.
(reg_class): Rename HI_REG to MD0_REG and LO_REG to MD1_REG.
(REG_CLASS_NAMES): Update accordingly.
* config/mips/mips.c (mips_dwarf_regno): New array.
(mips_regno_to_class): Rename HI_REG to MD0_REG and LO_REG to MD1_REG.
(mips_subword): Remove special handling for accumulator registers.
(override_options): Initiailize mips_dwarf_regno. Remove use
of ACC_HI_REG_P.
(mips_swap_registers): New function.
(mips_conditional_register_usage): Swap accumulator registers
around if TARGET_LITTLE_ENDIAN.
(mips_cannot_change_mode_class): Remove special treatment of ACC_REGS.
* config/mips/constraints.md (h, l): Use the endianness to choose
between MD0_REG and MD1_REG.
* config/mips/mips.md (*mfhilo_<mode>_macc): Use a fixed-string,
alternative-dependent template.
