--- Comment #1 from Jakub Jelinek <jakub at gcc dot gnu.org> ---
Why? I think it is pretty much the rule that -O1 can take 3-4 times as long as
-O0, the whole point of -O0 is that it bypasses most of the optimization
passes.
Your testcase is just huge, compiles to 31M assembly, there is not a single
optimization where significant time would be spent, most time takes garbage
collection (8%), tree CCP (7%), dominance (5%), the rest is below that.
