--- Comment #6 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-9 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:4486a537f14bc3b05ac552c3cbe18e540e397ed7 commit r9-8476-g4486a537f14bc3b05ac552c3cbe18e540e397ed7 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Apr 7 21:01:06 2020 +0200 objsz: Don't call replace_uses_by on SSA_NAME_OCCURS_IN_ABNORMAL_PHI [PR94423] The following testcase ICEs because the objsz pass calls replace_uses_by on SSA_NAME_OCCURS_IN_ABNORMAL_PHI SSA_NAME. The following patch instead of that calls replace_call_with_value, which will turn it into xyz_123(ab) = 234; 2020-04-01 Jakub Jelinek <ja...@redhat.com> PR middle-end/94423 * tree-object-size.c (pass_object_sizes::execute): Don't call replace_uses_by for SSA_NAME_OCCURS_IN_ABNORMAL_PHI lhs, instead call replace_call_with_value. * gcc.dg/ubsan/pr94423.c: New test.
