* doc/invoke.texi: Document -mabi=meabi, and expand on the EABI description. Document -mips32, -mips64, and the associated -march values. Describe the "mipsN" arguments to -march. Say that the -mipsN options are equivalent to -march. Reword the description of default type sizes. * toplev.h (target_flags_explicit): Declare. * toplev.c (target_flags_explicit): New var. (set_target_switch): Update target_flags_explicit. * config/mips/abi64.h (SUBTARGET_TARGET_OPTIONS): Undefine. * config/mips/elf64.h (MIPS_ISA_DEFAULT): Undefine. * config/mips/iris6.h (SUBTARGET_ASM_SPEC): -mabi=64 implies -mips3. * config/mips/isa3264.h (MIPS_ENABLE_EMBEDDED_O32): Undefine. * config/mips/mips.h (mips_cpu_info): New struct. (mips_cpu_string, mips_explicit_type_size_string): Remove. (mips_cpu_info_table, mips_arch_info, mips_tune_info): Declare. (MIPS_CPP_SET_PROCESSOR): New macro. (TARGET_CPP_BUILTINS): Declare a macro for each supported processor. Define _MIPS_ARCH and _MIPS_TUNE. (MIPS_ISA_DEFAULT): Don't provide a default value. Instead... (MIPS_CPU_STRING_DEFAULT): Set to "from-abi" if neither it nor MIPS_ISA_DEFAULT were already defined. (MULTILIB_DEFAULTS): Add MULTILIB_ABI_DEFAULT. (TARGET_OPTIONS): Remove -mcpu and -mexplicit-type-size. (ABI_NEEDS_32BIT_REGS, ABI_NEEDS_64BIT_REGS): New. (GAS_ASM_SPEC): Remove -march, -mcpu, -mgp* and -mabi rules. (ABI_GAS_ASM_SPEC): Remove. (MULTILIB_ABI_DEFAULT, ASM_ABI_DEFAULT_SPEC): New macros. (ASM_SPEC): Add -mgp32, -mgp64, -march, -mabi=eabi and -mabi=o64. Invoke %(asm_abi_default_spec) if no ABI was specified. (CC1_SPEC): Remove ISA -> register-size rules. (EXTRA_SPECS): Remove abi_gas_asm_spec. Add asm_abi_default_spec. * config/mips/mips.c (mips_arch_info, mips_tune_info): New vars. (mips_cpu_string, mips_explicit_type_size_string): Remove. (mips_cpu_info_table): New array. (mips_set_architecture, mips_set_tune): New fns. (override_options): Rework to make -mipsN equivalent to -march. Detect more erroneous cases, including those removed from CC1_SPEC. Don't change the ABI based on architecture, or vice versa. Unify logic with GAS. (mips_asm_file_start): Get architecture name from mips_arch_info. (mips_strict_matching_cpu_name_p, mips_matching_cpu_name_p): New fns. (mips_parse_cpu): Take the name of the option as argument. Handle 'from-abi'. Raise an error if the option is wrong. (mips_cpu_info_from_isa): New fn. [gcc/testsuite] * gcc.dg/mips-args-[123].c: New tests. From-SVN: r55747 |

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the file COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs.html for how to report bugs usefully.
