-fcf-protection is automatically enabled in libstdc++ on Linux/x86. Starting from commit 77d372abec0fbf2cfe922e3140ee3410248f979e Author: H.J. Lu <hjl.tools@gmail.com> Date: Thu Jan 14 05:56:46 2021 -0800 x86: Error on -fcf-protection with incompatible target GCC issues an error on -fcf-protection with incompatible target: ... -fcf-protection ... libstdc++-v3/testsuite/29_atomics/atomic_flag/test_and_set/explicit-hle.cc -m32 -O2 -g0 -fno-exceptions -fno-asynchronous-unwind-tables -march=i486 ... cc1plus: error: '-fcf-protection' is not compatible with this target FAIL: 29_atomics/atomic_flag/test_and_set/explicit-hle.cc (test for excess errors) Add -fcf-protection=none to -march=i486 to compile explicit-hle.cc. Checked it in as an obvious fix. * testsuite/29_atomics/atomic_flag/test_and_set/explicit-hle.cc: Add -fcf-protection=none to -march=i486. --- .../29_atomics/atomic_flag/test_and_set/explicit-hle.cc | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
