From: Jakub Jelinek <jakub@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r12-7446] testsuite: Add testcases for already fixed PR [PR100541] Date: Wed, 2 Mar 2022 09:41:26 +0000 (GMT) [thread overview] Message-ID: <20220302094126.0E9093858D37@sourceware.org> (raw) https://gcc.gnu.org/g:5f2e72db8c03c960d8330305c1e92986373198ca commit r12-7446-g5f2e72db8c03c960d8330305c1e92986373198ca Author: Jakub Jelinek <jakub@redhat.com> Date: Wed Mar 2 10:38:39 2022 +0100 testsuite: Add testcases for already fixed PR [PR100541] These testcases started failing with r12-630 and one of them got fixed with r12-4531 (aka PR102764 fix and r12-4616 further improved the fix) and the other went latent in r12-2591 (i.e. threader changes) and I believe was fixed for real by the PR102764 fix too. 2022-03-02 Jakub Jelinek <jakub@redhat.com> PR debug/100541 * g++.dg/opt/pr100541-1.C: New test. * g++.dg/opt/pr100541-2.C: New test.
