	* 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.
