Jakub Jelinek 26127932dd re PR c/53580 (Internal Segmentation fault in nested "omp parallel", "omp parallel for" and "omp parallel for reduction" Directives) ... PR middle-end/53580 * omp-low.c (scan_omp): Change first argument to gimple_seq *, call walk_gimple_seq_mod instead of walk_gimple_seq. (scan_sharing_clauses, scan_omp_parallel, scan_omp_task, scan_omp_for, scan_omp_sections, scan_omp_single, execute_lower_omp): Adjust callers. (scan_omp_1_stmt): Likewise. If check_omp_nesting_restrictions returns false, replace stmt with GIMPLE_NOP. (check_omp_nesting_restrictions): Instead of issuing warnings, issue errors and return false if any errors were reported. * gcc.dg/gomp/nesting-1.c: Expect errors rather than warnings. * gcc.dg/gomp/critical-4.c: Likewise. * gfortran.dg/gomp/appendix-a/a.35.1.f90: Likewise. * gfortran.dg/gomp/appendix-a/a.35.3.f90: Likewise. * gfortran.dg/gomp/appendix-a/a.35.4.f90: Likewise. * gfortran.dg/gomp/appendix-a/a.35.6.f90: Likewise. * c-c++-common/gomp/pr53580.c: New test. * testsuite/libgomp.c/pr26943-2.c: Remove #pragma omp barrier, use GOMP_barrier () call instead. * testsuite/libgomp.c/pr26943-3.c: Likewise. * testsuite/libgomp.c/pr26943-4.c: Likewise. * testsuite/libgomp.fortran/vla4.f90: Remove !$omp barrier, call GOMP_barrier instead. * testsuite/libgomp.fortran/vla5.f90: Likewise.
