x86: Add CpuCMOV and CpuFXSR
There are separate CPUID feature bits for fxsave/fxrstor and cmovCC
instructions. This patch adds CpuCMOV and CpuFXSR to replace Cpu686
on corresponding instructions.
gas/
* config/tc-i386.c (cpu_arch): Add .cmov and .fxsr.
(cpu_noarch): Add nocmov and nofxsr.
* doc/c-i386.texi: Document cmov and fxsr.
opcodes/
* i386-gen.c (cpu_flag_init): Add CpuCMOV and CpuFXSR to
CPU_I686_FLAGS. Add CPU_CMOV_FLAGS, CPU_FXSR_FLAGS,
CPU_ANY_CMOV_FLAGS and CPU_ANY_FXSR_FLAGS.
(cpu_flags): Add CpuCMOV and CpuFXSR.
* i386-opc.tbl: Replace Cpu686 with CpuFXSR on fxsave, fxsave64,
fxrstor and fxrstor64. Replace Cpu686 with CpuCMOV on cmovCC.
* i386-init.h: Regenerated.
* i386-tbl.h: Likewise.
