* config/i386/i386.h (TARGET_ABM): New define. (TARGET_POPCNT): Ditto. (TARGET_64BIT, TARGET_MMX, TARGET_3DNOW, TARGET_3DNOW_A, TARGET_SSE*): New temporary defines to redefine from OPTION_ISA_* defines. (MASK_64BIT, MASK_MMX, MASK_3DNOW, MASK_3DNOW_A, MASK_SSE*): New temporary defines to redefine from OPTION_MASK_ISA_* defines. (ix86_isa_flags): New extern int declaration. (TARGET_SUBTARGET_DEFAULT): New define. (TARGET_SUBTARGET_ISA_DEFAULT): Ditto. (TARGET_SUBTARGET32_DEFAULT): Ditto. (TARGET_SUBTARGET32_ISA_DEFAULT): Ditto. (TARGET_SUBTARGET64_ISA_DEFAULT): Ditto. * config/i386/unix.h: Undef TARGET_SUBTARGET_DEFAULT before define. * config/i386/darwin.h: Change TARGET_64BIT define to OPTION_ISA_64BIT. * config/i386/i386.opt (m3dnowa): Define as undocumented option using existing "ix86_isa_flags" varible. (m32, m64): Use existing "ix86_isa_flags" variable. (mmmx, m3dnow): Ditto. (msse, msse2, msse3, mssse3, msse4.1, msse4a): Ditto. (mabm): Define as non-negative option using "x86_abm" variable. (mpopcnt): Define as non-negative option using "x86_popcnt" variable. * config/i386/i386.c (ix86_arch_features) [X86_ARCH_CMOVE]: Rewrite feature test bitmap. (ix86_isa_flags): New initialized global int varible. (ix86_isa_flags_explicit): New static int variable. (ix86_handle_option): Set "ix86_isa_flags_explicit" when mmmx, m3dnow, msse, msse2, msse3, msse4.1 and msse4a option is processed. Change i86_isa_flags and ix86_isa_flags_explicit, not target_flags and target_flags_explicit. (override_options): Remove "target_enable" and "target_disable" fields from "struct ptt". Update processor_target_table accordingly. Remove PTA_PREFETCH_SSE from processor_alias_table entry if PTE_SSE is defined and rearrange PTA_* bits. Use "ix86_isa_flags" instead of "target_flags" and "ix86_isa_flags_explicit" instead of "target_flags_explicit" when masked with MASK_64BIT, MASK_MMX, MASK_3DNOW, MASK_3DNOW_A or MASK_SSE*. Set "x86_abm" to true when PTA_ABM is set in processor_alias_table flags entry. Set "x86_popcnt" to true when either of PTA_POPCNT or PTA_ABM is set in processor_alias_table flags entry. Set "x86_prefetch_sse" to true when either of PTA_PREFETCH_SSE or PTA_SSE is set in processor_alias_table flags entry. Remove handling of "target_enable" and "target_disable" fields of processor_target_table. Mask "target_flags" with TARGET_SUBTARGET32_DEFAULT for 32-bit targets or with TARGET_SUBTARGET64_DEFAULT for 64-bit targets. Mask "ix86_isa_flags" with TARGET_SUBTARGET32_ISA_DEFAULT for 32-bit targets or with TARGET_SUBTARGET64_ISA_DEFAULT for 64-bit targets. (def_builtin): Mask "mask" variable with "ix86_isa_flags", not "target_flags". (TARGET_DEFAULT_TARGET_FLAGS): Do not include TARGET_64BIT_DEFAULT. From-SVN: r125180
