Subject: x86: Don't check if AVX512 template requires AVX512VL
X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=c7face14225296a2f5d3ebeb8ace88c166d80c3e;p=binutils-gdb.git

x86: Don't check if AVX512 template requires AVX512VL

If the ZMM operand in an AVX12 template also allows XMM or ZMM, this
template must require AVX512VL.  Drop the AVX512VL requirement check
on such AVX512 templates.

	* config/tc-i386.c (check_VecOperands): Don't check if AVX512
	template requires AVX512VL.
