--- Comment #6 from Jakub Jelinek <jakub at gcc dot gnu.org> --- Weird, I still get exactly the same code (except for gcc version string) between pre-r205884 and post-r205884. So, what exact differences are you seeing on the testcase, and with -fdump-tree-all -da starting with what pass? Tried both a non-bootstrap gcc in my bisecting tree and 12 freshly built gcc x86_64 bootstraps from around Dec 5 till now. Because when I'm not able to reproduce it, I'm hesistant to adding the testcase...
