x86: Properly encode vmovd with 64-bit memeory
For historical reason, we allow movd/vmovd with 64-bit register and
memeory operands. But for vmovd, we failed to handle 64-bit memeory
operand. This has been gone unnoticed since AT&T syntax always treats
memory operand as 32-bit memory. This patch properly encodes vmovd
with 64-bit memeory operands. It also removes AVX512 vmovd with 64-bit
operands since GCC has
case TYPE_SSEMOV:
switch (get_attr_mode (insn))
{
case MODE_DI:
/* Handle broken assemblers that require movd instead of movq. */
if (!HAVE_AS_IX86_INTERUNIT_MOVQ
&& (GENERAL_REG_P (operands[0]) || GENERAL_REG_P (operands[1])))
return "%vmovd\t{%1, %0|%0, %1}";
return "%vmovq\t{%1, %0|%0, %1}";
and all AVX512 GNU assemblers set HAVE_AS_IX86_INTERUNIT_MOVQ, GCC won't
generate AVX512 vmovd with 64-bit operand.
