From: Tobias Burnus Date: Wed, 9 Sep 2020 07:33:51 +0000 (+0200) Subject: Fortran: Fixes for OpenMP loop-iter privatization (PRs 95109 + 94690) X-Git-Url: https://git.libre-soc.org/?a=commitdiff_plain;h=61c2d476a52bb108bd05d0226c5522bf0c4b24b5;p=gcc.git Fortran: Fixes for OpenMP loop-iter privatization (PRs 95109 + 94690) This commit also fixes a gfortran.dg/gomp/target1.f90 regression; target1.f90 tests the resolve.c and openmp.c changes. gcc/fortran/ChangeLog: PR fortran/95109 PR fortran/94690 * resolve.c (gfc_resolve_code): Also call gfc_resolve_omp_parallel_blocks for 'distribute parallel do (simd)'. * openmp.c (gfc_resolve_omp_parallel_blocks): Handle it. (gfc_resolve_do_iterator): Remove special code for SIMD, which is not needed. * trans-openmp.c (gfc_trans_omp_target): For TARGET_PARALLEL_DO_SIMD, call simd not do processing function. gcc/testsuite/ChangeLog: PR fortran/95109 PR fortran/94690 * gfortran.dg/gomp/combined-if.f90: Update scan-tree-dump-times for 'omp simd.*if'. * gfortran.dg/gomp/openmp-simd-5.f90: New test. --- diff --git a/gcc/fortran/openmp.c b/gcc/fortran/openmp.c index d0e516c472d..1efce33e519 100644 --- a/gcc/fortran/openmp.c +++ b/gcc/fortran/openmp.c @@ -5962,6 +5962,8 @@ gfc_resolve_omp_parallel_blocks (gfc_code *code, gfc_namespace *ns) switch (code->op) { + case EXEC_OMP_DISTRIBUTE_PARALLEL_DO: + case EXEC_OMP_DISTRIBUTE_PARALLEL_DO_SIMD: case EXEC_OMP_PARALLEL_DO: case EXEC_OMP_PARALLEL_DO_SIMD: case EXEC_OMP_TARGET_PARALLEL_DO: @@ -6047,31 +6049,6 @@ gfc_resolve_do_iterator (gfc_code *code, gfc_symbol *sym, bool add_clause) if (omp_current_ctx->sharing_clauses->contains (sym)) return; - if (omp_current_ctx->is_openmp && omp_current_ctx->code->block) - { - /* SIMD is handled differently and, hence, ignored here. */ - gfc_code *omp_code = omp_current_ctx->code->block; - for ( ; omp_code->next; omp_code = omp_code->next) - switch (omp_code->op) - { - case EXEC_OMP_SIMD: - case EXEC_OMP_DO_SIMD: - case EXEC_OMP_PARALLEL_DO_SIMD: - case EXEC_OMP_DISTRIBUTE_SIMD: - case EXEC_OMP_DISTRIBUTE_PARALLEL_DO_SIMD: - case EXEC_OMP_TEAMS_DISTRIBUTE_SIMD: - case EXEC_OMP_TARGET_TEAMS_DISTRIBUTE_SIMD: - case EXEC_OMP_TEAMS_DISTRIBUTE_PARALLEL_DO_SIMD: - case EXEC_OMP_TARGET_TEAMS_DISTRIBUTE_PARALLEL_DO_SIMD: - case EXEC_OMP_TARGET_PARALLEL_DO_SIMD: - case EXEC_OMP_TARGET_SIMD: - case EXEC_OMP_TASKLOOP_SIMD: - return; - default: - break; - } - } - if (! omp_current_ctx->private_iterators->add (sym) && add_clause) { gfc_omp_clauses *omp_clauses = omp_current_ctx->code->ext.omp_clauses; diff --git a/gcc/fortran/resolve.c b/gcc/fortran/resolve.c index ebf89a9b1f5..f4ce49f8432 100644 --- a/gcc/fortran/resolve.c +++ b/gcc/fortran/resolve.c @@ -11722,6 +11722,8 @@ gfc_resolve_code (gfc_code *code, gfc_namespace *ns) omp_workshare_flag = 1; gfc_resolve_omp_parallel_blocks (code, ns); break; + case EXEC_OMP_DISTRIBUTE_PARALLEL_DO: + case EXEC_OMP_DISTRIBUTE_PARALLEL_DO_SIMD: case EXEC_OMP_PARALLEL: case EXEC_OMP_PARALLEL_DO: case EXEC_OMP_PARALLEL_DO_SIMD: diff --git a/gcc/fortran/trans-openmp.c b/gcc/fortran/trans-openmp.c index 7d3365fe7e0..0e1da0426b4 100644 --- a/gcc/fortran/trans-openmp.c +++ b/gcc/fortran/trans-openmp.c @@ -5591,13 +5591,19 @@ gfc_trans_omp_target (gfc_code *code) } break; case EXEC_OMP_TARGET_PARALLEL_DO: - case EXEC_OMP_TARGET_PARALLEL_DO_SIMD: stmt = gfc_trans_omp_parallel_do (code, &block, clausesa); if (TREE_CODE (stmt) != BIND_EXPR) stmt = build3_v (BIND_EXPR, NULL, stmt, poplevel (1, 0)); else poplevel (0, 0); break; + case EXEC_OMP_TARGET_PARALLEL_DO_SIMD: + stmt = gfc_trans_omp_parallel_do_simd (code, &block, clausesa); + if (TREE_CODE (stmt) != BIND_EXPR) + stmt = build3_v (BIND_EXPR, NULL, stmt, poplevel (1, 0)); + else + poplevel (0, 0); + break; case EXEC_OMP_TARGET_SIMD: stmt = gfc_trans_omp_do (code, EXEC_OMP_SIMD, &block, &clausesa[GFC_OMP_SPLIT_SIMD], NULL_TREE); diff --git a/gcc/testsuite/gfortran.dg/gomp/combined-if.f90 b/gcc/testsuite/gfortran.dg/gomp/combined-if.f90 index 0bb6c28b286..d9e4a26ca0c 100644 --- a/gcc/testsuite/gfortran.dg/gomp/combined-if.f90 +++ b/gcc/testsuite/gfortran.dg/gomp/combined-if.f90 @@ -104,6 +104,6 @@ contains end module ! { dg-final { scan-tree-dump-times "(?n)#pragma omp target.* if\\(" 9 "omplower" } } -! { dg-final { scan-tree-dump-times "(?n)#pragma omp simd.* if\\(" 4 "omplower" { target { ! offload_nvptx } } } } +! { dg-final { scan-tree-dump-times "(?n)#pragma omp simd.* if\\(" 5 "omplower" { target { ! offload_nvptx } } } } ! { dg-final { scan-tree-dump-times "(?n)#pragma omp simd.* if\\(" 7 "omplower" { target { offload_nvptx } } } } ! { dg-final { scan-tree-dump-times "(?n)#pragma omp parallel.* if\\(" 6 "omplower" } } diff --git a/gcc/testsuite/gfortran.dg/gomp/openmp-simd-5.f90 b/gcc/testsuite/gfortran.dg/gomp/openmp-simd-5.f90 new file mode 100644 index 00000000000..b6d4cfa7080 --- /dev/null +++ b/gcc/testsuite/gfortran.dg/gomp/openmp-simd-5.f90 @@ -0,0 +1,24 @@ +! { dg-additional-options "-fdump-tree-original" } +! +!
