OpenMP 5.1 says: For any directive that has a paired end directive, including those with a begin and end pair, both directives must use either the attribute syntax or the pragma syntax. The following patch enforces it with the only pair so far recognized in C++ (Fortran has many, but on the other side doesn't have attribute syntax). While I initially wanted to use vec<bool, va_gc> *member; in there, that unfortunately doesn't work, one gets linker errors and I guess it is fixable, but for begin declare target we'll need a struct anyway to store device_type etc. 2021-08-12 Jakub Jelinek <jakub@redhat.com> * cp-tree.h (omp_declare_target_attr): New type. (struct saved_scope): Change type of omp_declare_target_attribute from int to vec<omp_declare_target_attr, va_gc> * and move it. * parser.c (cp_parser_omp_declare_target): Instead of incrementing scope_chain->omp_declare_target_attribute, push a struct containing parser->lexer->in_omp_attribute_pragma to the vector. (cp_parser_omp_end_declare_target): Instead of decrementing scope_chain->omp_declare_target_attribute, pop a structure from it. Diagnose mismatching declare target vs. end declare target syntax. * semantics.c (finish_translation_unit): Use vec_safe_length and vec_safe_truncate on scope_chain->omp_declare_target_attributes. * decl2.c (cplus_decl_attributes): Use vec_safe_length on scope_chain->omp_declare_target_attributes. * g++.dg/gomp/attrs-12.C: New test. |

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.
