[PATCH] x86: Default CET run-time support to auto

2020-05-08 Thread H.J. Lu via Gcc-patches
CET has been added since GCC 8. This patch defaults CET run-time support to auto. It enables CET run-time support if asssembler supports CET instructions and multi-byte NOPs are enabled via SSE2. OK for master? Thanks. H.J. --- config/ * cet.m4 (GCC_CET_FLAGS): Change default to auto.
