(mips_sw_reg_names): Consistently use $ as name prefix.
(large_int): Handle 64 bit constants.
(reg_or_0_operand, mips_const_double_ok): Don't examine
CONST_DOUBLE internals.
(mips_const_double_ok): Use REAL_VALUE_* macros.
(simple_memory_operand): Add 64 bit support. Only test
TARGET_GP_OPT to determine if doing gp optimizations. Pass
address not MEM to eliminate_constant_term. Use SMALL_INT.
(mips_fill_delay_slot): Add 64 bit support.
(mips_move_1word): Add 64 bit support. Don't examine CONST_DOUBLE
internals.
(mips_move_2words): Likewise.
(mips_address_cost): Pass address not MEM to
eliminate_constant_term. Use SMALL_INT.
(gen_int_relational): New variable mode. Add 64 bit support.
(gen_conditional_branch): Add 64 bit support.
(block_move_load_store, block_move_loop, block_move_call,
expand_block_move, output_block_move, function_arg_advance,
function_arg, function_arg_partial_nregs): Likewise.
(override_options): Clear MASK_GPOPT if threshold is zero or
negative. Set MASK_GPOPT if optimizing. Set mips_isa from -misa=
option, else from MIPS_ISA_DEFAULT if defined, else to 1. Make
default cpu depend on isa. Add cpus r4400, r4600, orion. Rewrite
TARGET_NAME_REGS support. Initialize dfhigh, dflow, sfhigh,
sflow. Add 64 bit support.
(print_operand): Use REAL_VALUE_* macros.
(mips_output_external): Don't depend on mips_section_threshold.
(make_temp_file): Define P_tmpdir when __MSDOS__. Malloc filename
string. Don't unlink temp file when __MSDOS__.
(mips_asm_file_start): Delete TARGET_NAME_REGS support.
(mips_asm_file_end): Unlike temp file when __MSDOS__.
(mips_declare_object): Don't test mips_sections_threshold.
(compute_frame_size, save_restore_insns, function_prologue,
mips_expand_prologue, function_epilogue, mips_expand_epilogue):
Add 64 bit support.
(function_epilogue): Correctly output `#' before .set volatile.
