--- Comment #28 from Jerry DeLisle <jvdelisle at gcc dot gnu.org> 2011-04-18 18:46:00 UTC --- This optimization test case is cute. We should ship it to the optimization folks. And it should be yet another PR, even if we can come up with a work around. I am not going to have time to look further on this for a few days. Thomas, could you open a PR for the optimization issue and attache your c test case to it. Then add a refrence here to that new PR. Make sure you put the word "Optimization" in the PR summary so the right folks will notice it. and thanks for the great sleuthing! I am time compressed, as most of us are.
