From: Andrew Pinski <apin...@marvell.com>
So I was looking at some older PRs (PR 16016 in this case),
I noticed that some of the testcases were removed when
the tree-ssa branch was merged. This adds them back in.
OK? Bootstrapped and tested on x86_64-linux-gnu with no regressions.
Thanks,
Andrew Pinski
