-Subject: [PATCH] lib/x86: increase AVX-VNNI gcc prerequisite to 12.1
-
-Although gcc 11.1 supports AVX-VNNI, a popular distro pairs it with a
-binutils version that does not.  Require gcc 12 instead.
-
-Resolves https://github.com/ebiggers/libdeflate/issues/365

-+ * Unusually for a new CPU feature, gcc added support for the AVX-VNNI
