GCC modified for the FreeChainXenon project
f469ce1d3e
This patch adjusts OpenMP/OpenACC clause list handling in a couple of places, in preparation for the following mapping-clause expansion rework patch. Firstly mapping groups are removed as a whole in the C and C++ front-ends when an error is detected, which avoids leaving "badly-formed" mapping clause groups in the list. Secondly, reindexing of the omp_mapping_group hashmap (during omp_build_struct_sibling_lists) has been reimplemented, fixing some tricky corner-cases where mapping groups are removed from a list at the same time as it is being reordered. Thirdly, code to check if a different clause on the same directive maps the whole of a struct that we have a component mapping for (for example) has been outlined, removing a bit of code duplication. 2022-09-13 Julian Brown <julian@codesourcery.com> gcc/ * gimplify.cc (omp_group_last): Allow GOMP_MAP_ATTACH_DETACH after GOMP_MAP_STRUCT (for reindexing). (omp_gather_mapping_groups): Reimplement using... (omp_gather_mapping_groups_1): This new function. Stop processing at GATHER_SENTINEL. (omp_group_base): Allow GOMP_MAP_TO_PSET without any following node. (omp_index_mapping_groups): Reimplement using... (omp_index_mapping_groups_1): This new function. Handle REINDEX_SENTINEL. (omp_reindex_mapping_groups, omp_mapped_by_containing_struct): New functions. (omp_tsort_mapping_groups_1): Adjust handling of base group being the same as current group. Use omp_mapped_by_containing_struct. (omp_build_struct_sibling_lists): Use omp_mapped_by_containing_struct and omp_reindex_mapping_groups. Robustify group deletion for reordered lists. (gimplify_scan_omp_clauses): Update calls to omp_build_struct_sibling_lists. gcc/c/ * c-typeck.cc (c_finish_omp_clauses): Remove whole mapping node group on error. gcc/cp/ * semantics.cc (finish_omp_clauses): Likewise. |

This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
