--- Comment #8 from Richard Biener <rguenth at gcc dot gnu.org> --- (In reply to Marek Polacek from comment #7) > Is there any chance that this fix could be backported to 11 or is it too > risky? To fix this bug it should be enough to backport the following part: * tree-ssa-pre.c (prune_clobbered_mems): Also prune trapping references when the BB may not return. I'll check and do that.
