--- Comment #4 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jeff Law <l...@gcc.gnu.org>: https://gcc.gnu.org/g:db24bdc743cf23ea12d2dcf8254d86ab366bb46d commit r13-3211-gdb24bdc743cf23ea12d2dcf8254d86ab366bb46d Author: Jeff Law <jeffreya...@gmail.com> Date: Tue Oct 11 00:44:26 2022 -0400 [PR rtl-optimization/107182] Clear EDGE_CROSSING for jump->ret optimization When turning a jump to a return into a return, we need to clear EDGE_CROSSING of the fallthru edge to prevent a checking failure. I considered not applying the transformation when the edge has EDGE_CROSSING set, but it still seems like we ought to eliminate the unnecessary jump in that case. gcc/ PR rtl-optimization/107182 * cfgrtl.cc (fixup_reorder_chain): When optimizing a jump to a return, clear EDGE_CROSSING on the appropriate edge.
