x86: Check VEX/EVEX encoding before checking vector operands
Since
commit 837e225ba1992f9745e5bbbd5e8443243a7f475f
Author: Jan Beulich <jbeulich@suse.com>
Date: Thu Oct 20 10:01:12 2022 +0200
x86: re-work AVX-VNNI support
moved AVX-VNNI after AVX512-VNNI, vector Disp8 is applied even when VEX
encoding is selected. Check VEX/EVEX encoding before checking vector
operands to avoid vector Disp8 with VEX encoding.
PR gas/29708
* config/tc-i386.c (match_template): Check VEX/EVEX encoding
before checking vector operands.
* testsuite/gas/i386/avx-vnni.d: Updated.
* testsuite/gas/i386/x86-64-avx-vnni.d: Likewise.
* testsuite/gas/i386/avx-vnni.s: Add a Disp32 test.
* testsuite/gas/i386/x86-64-avx-vnni.s: Likewise.
