--- Comment #7 from CVS 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:994ea892bd02dd8a1c04875ad3553c57939c3abf commit r13-2617-g994ea892bd02dd8a1c04875ad3553c57939c3abf Author: Jakub Jelinek <ja...@redhat.com> Date: Mon Sep 12 10:48:19 2022 +0200 libgomp: Fix up icv-6.c [PR106894] The thing is, make check or make check RUNTESTFLAGS="c.exp='icv-6.c' c++.exp='icv-6.c'" in libgomp obj dir work fine, but make -j32 -k check RUNTESTFLAGS="c.exp='icv-6.c' c++.exp='icv-6.c'" fails. The thing is that the testcase as written relies on OMP_NUM_THREADS not being set in environment (as it takes priority over OMP_NUM_THREADS_ALL for the host). So, if either a user has OMP_NUM_THREADS=42 in the environment by himself, or when doing make check with -jN, we trigger: if test $$num_cpus -gt 8 && test -z "$$OMP_NUM_THREADS"; then \ OMP_NUM_THREADS=8; export OMP_NUM_THREADS; \ echo @@@ libgomp OMP_NUM_THREADS adjusted to 8 because of parallel make check and too many CPUs; \ fi; \ in libgomp/testsuite/Makefile.am and so the test fails. 2022-09-12 Jakub Jelinek <ja...@redhat.com> PR libgomp/106894 * testsuite/libgomp.c-c++-common/icv-6.c: Include string.h. (main): Avoid tests for which corresponding non-_ALL suffixed variable is in the environment, or for OMP_NUM_TEAMS on the device OMP_NUM_TEAMS_DEV_?.
