OpenMP 5.0 also specifies that functions referenced from target regions (except for target regions with device(ancestor:)) are also implicitly declare target to. This patch implements that. 2020-05-14 Jakub Jelinek <jakub@redhat.com> * function.h (struct function): Add has_omp_target bit. * omp-offload.c (omp_discover_declare_target_fn_r): New function, old renamed to ... (omp_discover_declare_target_tgt_fn_r): ... this. (omp_discover_declare_target_var_r): Call omp_discover_declare_target_tgt_fn_r instead of omp_discover_declare_target_fn_r. (omp_discover_implicit_declare_target): Also queue functions with has_omp_target bit set, for those walk with omp_discover_declare_target_fn_r, for declare target to functions walk with omp_discover_declare_target_tgt_fn_r. gcc/c/ * c-parser.c (c_parser_omp_target): Set cfun->has_omp_target. gcc/cp/ * cp-gimplify.c (cp_genericize_r): Set cfun->has_omp_target. gcc/fortran/ * trans-openmp.c: Include function.h. (gfc_trans_omp_target): Set cfun->has_omp_target. libgomp/ * testsuite/libgomp.c-c++-common/target-40.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.
