From 453954451be68d22462442268a29f54809182d2b Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Tue, 19 May 2020 14:42:12 -0700 Subject: [PATCH] x86: Add FEATURE_AVX512VP2INTERSECT and update GFNI check Add FEATURE_AVX512VP2INTERSECT to libgcc so that enum processor_features in libgcc matches enum processor_features in i386-builtins.c. Update GFNI check to support processors with SSE and AVX versions of GFNI. PR target/95212 PR target/95220 * config/i386/cpuinfo.c (get_available_features): Fix FEATURE_GFNI check.
