From 16664e6e4fb4281be6477c13989740d44c963c77 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 9 Oct 2020 06:12:17 -0700 Subject: [PATCH] x86-64: Check CMPXCHG16B for x86-64-v[234] x86-64-v2 includes CMPXCHG16B. Since -mcx16 enables CMPXCHG16B and defines __GCC_HAVE_SYNC_COMPARE_AND_SWAP_16, check it in x86-64-v[234] tests.
