From: Jakub Jelinek <jakub@gcc.gnu.org> To: gcc-cvs@gcc.gnu.org Subject: [gcc r12-936] openmp: Handle explicit linear clause properly in combined constructs with target [PR99928] Date: Thu, 20 May 2021 07:20:01 +0000 (GMT) [thread overview] Message-ID: <20210520072001.E89A8394FC1B@sourceware.org> (raw) https://gcc.gnu.org/g:94fa4c67b95c12482b6087d8eef2d72f7b7ea254 commit r12-936-g94fa4c67b95c12482b6087d8eef2d72f7b7ea254 Author: Jakub Jelinek <jakub@redhat.com> Date: Thu May 20 09:17:40 2021 +0200 openmp: Handle explicit linear clause properly in combined constructs with target [PR99928] linear clause should have the effect of firstprivate+lastprivate (or for IVs not declared in the construct lastprivate) on outer constructs and eventually map(tofrom:) on target when combined with it. 2021-05-20 Jakub Jelinek <jakub@redhat.com> PR middle-end/99928 * gimplify.c (gimplify_scan_omp_clauses) <case OMP_CLAUSE_LINEAR>: For explicit linear clause when combined with target, make it map(tofrom:) instead of no clause or firstprivate. * c-c++-common/gomp/pr99928-4.c: Remove all xfails. * c-c++-common/gomp/pr99928-5.c: Likewise.
