New Revision: 350778
URL: https://svnweb.freebsd.org/changeset/base/350778
Log:
Stopgap fix for gcc platforms.
Our in-tree gcc doesn't have a no-tree-vectorize optimization knob, so we get
a
warning that it's unused. This causes the build to fail on all our gcc
platforms.
Add a quick version check as a stop-gap measure to get CI building again.
