Yep, I know about this commit.
I suspect g:6c35d16a3925958b3a22426de0cb8e04f654b6dd where e.g. sse detecti=

and rather:
+      else if (has_feature (FEATURE_SSE2)

is used. And then in g:792317cc777123b9cac8fc9a70fc85b01a3d7a0f newly added
get_available_features
which does the ISA features detection is called only for AMD and Intel CPUs=
