r173265 | uros | 2011-05-02 14:58:32 -0400 (Mon, 02 May 2011) | 13 lines
* config/i386/mmx.md (*mov<mode>_internal_rex64): Use %vmovq for
reg<->xmm moves.
(*mov<mode>_internal): Merge with *mov<mode>_internal_avx.
(*movv2sf_internal_rex64): Use %vmovq for reg<->xmm moves. Merge
with *movv2sf_internal_rex64_avx.
(*movv2sf_internal): Merge with *movv2sf_internal_avx.
* config/i386/i386.md (*movdi_internal_rex64) <TYPE_SSEMOV>:
Use %v prefix in insn mnemonic to handle TARGET_AVX.
(*movdi_internal): Add "isa" attribute. Use "maybe_vex" instead of
"vex" in "prefix" attribute calculation.
(*movdf_internal): Output AVX mnemonics. Add "prefix" attribute.
