Aldy Hernandez <aldyh at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |aldyh at gcc dot gnu.org --- Comment #2 from Aldy Hernandez <aldyh at gcc dot gnu.org> --- There is already PR101674 for the uninit-pred-9.c regression. The 20050826-2.c may be related to PR101690 which was caused by inconsistent profile estimates as well. Jeff commented that the backwards threader probably doesn't set profile estimates correctly: https://gcc.gnu.org/pipermail/gcc-patches/2021-July/576437.html
