Subject: [Qemu-devel] [PATCH v2 0/2] AVX2 configure fixes
Date: Wed, 1 Jun 2016 15:54:37 +0100 [thread overview]
Message-ID: <1464792879-30954-1-git-send-email-dgilbert@redhat.com> (raw)
From: "Dr. David Alan Gilbert" <dgilbert@redhat.com>
Hi,
This pair of patches fixes a couple of issues that we found during test.
The first is that the configure test is pessimistic when compiled with -O2,
the second is that the explicit 4.9 gcc test is a bit coarse; I've removed
that test but beefed up the ./configure test to actually use the avx2
intrinsics and that fails in the same way as the main code, so it works
in the same way as the explicit check but allows older gcc's to work
when -save-temps isn't used.
Dave
v2
Remove the explicit version check
Split the patches

Make avx2 configure test work with -O2
