--- Comment #8 from CVS Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-12 branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:8e74c4389ce242b571cc182b19e88b7c08656145 commit r12-9150-g8e74c4389ce242b571cc182b19e88b7c08656145 Author: Jakub Jelinek <ja...@redhat.com> Date: Thu Feb 2 09:54:18 2023 +0100 nested, openmp: Wrap OMP_CLAUSE_*_GIMPLE_SEQ into GIMPLE_BIND for declare_vars [PR108435] When gimplifying OMP_CLAUSE_{LASTPRIVATE,LINEAR}_STMT, we wrap it always into a GIMPLE_BIND, but when putting statements directly into OMP_CLAUSE_{LASTPRIVATE,LINEAR}_GIMPLE_SEQ, we do it only if needed (there are any temporaries that need to be declared in the sequence). convert_nonlocal_omp_clauses was relying on the GIMPLE_BIND to be there always because it called declare_vars on it. The following patch wraps it into GIMPLE_BIND in tree-nested if we need to declare_vars on it on demand. 2023-02-02 Jakub Jelinek <ja...@redhat.com> PR middle-end/108435 * tree-nested.cc (convert_nonlocal_omp_clauses) <case OMP_CLAUSE_LASTPRIVATE>: If info->new_local_var_chain and *seq is not a GIMPLE_BIND, wrap the sequence into a new GIMPLE_BIND before calling declare_vars. (convert_nonlocal_omp_clauses) <case OMP_CLAUSE_LINEAR>: Merge with the OMP_CLAUSE_LASTPRIVATE handling except for whether seq is initialized to &OMP_CLAUSE_LASTPRIVATE_GIMPLE_SEQ (clause) or &OMP_CLAUSE_LINEAR_GIMPLE_SEQ (clause). * gcc.dg/gomp/pr108435.c: New test.
