[gas/]
* doc/c-mips.texi: Remove -mcpu. Document -mabi.
* configure.in (MIPS_CPU_STRING_DEFAULT): New configuration macro.
(USE_E_MIPS_ABI_O32, MIPS_DEFAULT_64BIT): New configuration macros.
* configure, config.in: Regenerate.
* config/tc-mips.c (file_mips_abi): Rename to mips_abi.
(mips_set_options): Remove "abi" field.
(mips_opts): Update accordingly. Replace all uses of mips_opts.abi
with mips_abi.
(mips_cpu): Remove.
(mips_arch_string, mips_arch_info): New vars.
(mips_tune_string, mips_tune_info): New vars.
(ABI_NEEDS_32BIT_REGS, ABI_NEEDS_64BIT_REGS): New macros.
(HAVE_32BIT_GPRS, HAVE_32BIT_FPRS): Don't check the ABI.
(mips_isa_to_str, mips_cpu_to_str): Remove.
(mips_ip): If the selected architecture is a generic ISA rather
than a processor, only mention the ISA level in error messages.
(OPTION_MCPU): Remove.
(OPTION_FP64): New.
(md_longopts): Add -mfp64, remove -mcpu.
(mips_set_option_string): New fn.
(md_parse_option): Make -mipsN update file_mips_isa rather than
mips_opts.isa. Use mips_set_option_string to set -march or -mtune.
Don't let -mgp32 and -mfp32 change the ABI.
(show): Move to end of file. Constify string argument.
(md_show_usage): Move to the end of the file. Read available
architectures from mips_cpu_info_table.
(mips_set_architecture): New fn.
(mips_after_parse_args): Rework. Remove -mcpu handling. -mipsN
is an alias for -march=mipsN. Don't change the ABI based on other
flags. Infer the register size from the ABI as well as the
architecture. Complain about more conflicting arguments.
Unify logic with GCC.
(s_mipsset): Don't change the ABI.
(mips_elf_final_processing): Check USE_E_MIPS_ABI_O32.
(mips_cpu_info_table): Remove Generic-MIPS* entries, keeping just
"mipsN"-type entries. Remove entries that vary only in the
manufacturer's prefix, or that have "000" replaced by "k".
Remove TARGET_CPU entries. Make r2000 entry use CPU_R3000.
(mips_strict_matching_cpu_name_p, mips_matching_cpu_name_p): New fns.
(mips_parse_cpu): New fn.
(mips_cpu_info_from_name, mips_cpu_info_from_cpu): Remove.
(mips_cpu_info_from_isa): Minor formatting tweak.
[gas/testsuite]
* gas/mips/mips-gp32-fp64.d,
* gas/mips/mips-gp32-fp64-pic.d: Add -mfp64.
