[PATCH v2] x86: recognize both avx10.1aux and avx10v1aux

Rohan Shenoy RohanRadhesh.Shenoy@amd.com
Thu Aug 20 07:05:03 GMT 2026 

Accept both as names for the same feature. Keep existing naming 
(avx10.1aux) while adding avx10v1aux, as the latter aligns with
gcc (and Clang eventually).

gas/
	* config/tc-i386.c: Recognize avx10v1aux as an alias of avx10.1aux.
	* doc/c-i386.texi: Document avx10v1aux alongside avx10.1aux.
	* testsuite/gas/i386/i386.exp: Update test names accordingly.
	* testsuite/gas/i386/avx10v1aux-*: Rename from testsuite/gas/i386/avx10.1-aux-*.
---

Notes:
    Changes in v2:
    - Adds avx10v1aux rather than replacing avx10.1aux as per Jan's 
    suggestion [1].
    - Update two of the four tests (256-cvt, 512-media) to use arch 
    avx10.1aux, so that both names are used.
