The Fortran front end was giving an ICE instead of a user-friendly diagnostic when variants of a metadirective variant had different statement associations. The particular test case reported in the issue also involved invalid placement of the "omp end metadirective" which was not being diagnosed either. gcc/fortran/ChangeLog PR middle-end/107067 * parse.cc (parse_omp_do): Diagnose missing "OMP END METADIRECTIVE" after loop. (parse_omp_structured_block): Likewise for strictly structured block. (parse_omp_metadirective_body): Use better test for variants ending at different places. Issue a user diagnostic at the end if any were inconsistent, instead of calling gcc_assert. gcc/testsuite/ChangeLog PR middle-end/107067 * gfortran.dg/gomp/metadirective-11.f90: Remove the dg-ice, update for current behavior, and add more tests to exercise the new error code.
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.
