--- Comment #16 from Marc Glisse <glisse at gcc dot gnu.org> --- (In reply to Rich Felker from comment #15) > Can you clarify? As far as I can tell, the other bug is a missed > optimization and this is an overly-aggressive, incorrect optimization. The same test is wrong, it optimizes cases it shouldn't and doesn't optimize cases it should (I am not familiar enough to tell, just trusting you), goes together. Having testcases in both directions will be useful when Jan (or someone else) rewrites it.
