4Subject: [PATCH] * config/i386/i386.md (*movdi_internal_rex64) <TYPE_SSEMOV>:
5 Use %v prefix in insn mnemonic to handle TARGET_AVX.
6 (*movdi_internal): Use "maybe_vex" instead of "vex" in "prefix"
7 attribute calculation.
8 (*movdf_internal): Output AVX mnemonics. Add "prefix" attribute.
9 * config/i386/sse.md (*sse2_storeq_rex64): Do not emit %v prefix
10 for mov{q} mnemonic.
11 (*vec_extractv2di_1_rex64_avx): Ditto.
