From 4c1a5d8b71e29b71e0bc1004480c12c5fc427cb7 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Fri, 15 May 2020 09:06:50 -0700 Subject: x86: Also check if -fcf-protection works When defaulting CET run-time support to auto, check if -fcf-protection works. Even if the stage1 GCC doesn't support -fcf-protection, since the final GCC does, CET run-time support will be enabled by default if binutils support CET. config/ PR bootstrap/95147 * cet.m4 (GCC_CET_FLAGS): Also check if -fcf-protection works when defaulting to auto. libatomic/ PR bootstrap/95147 * configure: Regenerated. libbacktrace/ PR bootstrap/95147 * configure: Regenerated. libgcc/ PR bootstrap/95147 * configure: Regenerated. libgfortran/ PR bootstrap/95147 * configure: Regenerated. libgomp/ PR bootstrap/95147 * configure: Regenerated. libitm/ PR bootstrap/95147 * configure: Regenerated. libobjc/ PR bootstrap/95147 * configure: Regenerated. libphobos/ PR bootstrap/95147 * configure: Regenerated. libquadmath/ PR bootstrap/95147 * configure: Regenerated. libsanitizer/ PR bootstrap/95147 * configure: Regenerated. libssp/ PR bootstrap/95147 * configure: Regenerated. libstdc++-v3/ PR bootstrap/95147 * configure: Regenerated. libvtv/ PR bootstrap/95147 * configure: Regenerated. zlib/ PR bootstrap/95147 * configure: Regenerated. --- libquadmath/ChangeLog | 5 +++++ libquadmath/configure | 3 +++ 2 files changed, 8 insertions(+) (limited to 'libquadmath') diff --git a/libquadmath/ChangeLog b/libquadmath/ChangeLog index fbb548e..eb04541 100644 --- a/libquadmath/ChangeLog +++ b/libquadmath/ChangeLog @@ -1,3 +1,8 @@ +2020-05-15 H.J.
