Subject: [PULL 3/7] configure: Add -Werror to avx2, avx512 tests
Date: Thu, 29 Jul 2021 14:47:09 +0200	[thread overview]
Message-ID: <20210729124713.208422-4-pbonzini@redhat.com> (raw)
In-Reply-To: <20210729124713.208422-1-pbonzini@redhat.com>

From: Richard Henderson <richard.henderson@linaro.org>

When using clang, we get

ERROR: configure test passed without -Werror but failed with -Werror.
       This is probably a bug in the configure script. The failing command
       will be at the bottom of config.log.
       You can run configure with --disable-werror to bypass this check.

What we really want from these two tests is whether the
entire code sequence is supported, including pragmas.
Adding -Werror makes the test properly fail for clang.
