Bug ID: 20140
Summary: CpuAVX512VL should be treated like Cpu64
Product: binutils
Version: 2.27 (HEAD)
Status: NEW
Severity: normal
Priority: P2
Component: gas
Assignee: unassigned at sourceware dot org
Reporter: hjl.tools at gmail dot com
CC: kirill.yukhin at intel dot com
Target Milestone: ---
Target: x86
An 128-bit AVX512CD instruction
vpconflictd %xmm0, %xmm15
requires AVX512VL. But I got
[hjl@gnu-6 tmp]$ cat a.s
.arch corei7
.arch .avx512f
.arch .avx512cd
vpconflictd %xmm0, %xmm15
[hjl@gnu-6 tmp]$ gcc -c a.s
[hjl@gnu-6 tmp]$
It should be an error.
