--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:c89714d9df3ad8dd6b79946da85f5e276aba83db commit r15-9209-gc89714d9df3ad8dd6b79946da85f5e276aba83db Author: Jakub Jelinek <ja...@redhat.com> Date: Fri Apr 4 20:53:19 2025 +0200 profile: Another musttail fix [PR119618] As the following testcase shows, sometimes we can have debug stmts after a musttail call and profile.cc in that case would incorrectly allow the edge from that, causing musttail error and -fcompare-debug failure (because if there are no debug stmts after it, then musttail is found there and the edge is ignored). The following patch uses gsi_last_nondebug_bb instead of gsi_last_bb to find the musttail call. And so that we don't uselessly skip over debug stmts at the end of many bbs, the patch limits it to cfun->has_musttail functions. 2025-04-04 Jakub Jelinek <ja...@redhat.com> PR gcov-profile/119618 * profile.cc (branch_prob): Only check for musttail calls if cfun->has_musttail. Use gsi_last_nondebug_bb instead of gsi_last_bb. * c-c++-common/pr119618.c: New test.
