--- Comment #11 from Marko Mäkelä <marko.makela at mariadb dot com> --- I apologize for my inaccurate claim that the AMD Zen 5 would be capable of full AVX10.1. In any case, EVEX512 definitely is supported. Based on https://en.wikipedia.org/wiki/Advanced_Vector_Extensions#AVX10 and the table in https://en.wikipedia.org/wiki/AVX-512#CPUs_with_AVX-512 it looks like the AMD Zen 5 microarchitecture is missing the FP16 feature. If the related instructions cannot be "accidentally" emitted for target("avx10.1"), only by specific intrinsic functions or inline assembler code, then there should be no issue related to that. (GCC is removing the more specific AVX-512 feature flags; that is why the broader "avx10.1" needs to be used.)
