This implements strictly-structured blocks support for Fortran, as specified in OpenMP 5.2. This now allows using a Fortran BLOCK construct as the body of most OpenMP constructs, with a "!$omp end ..." ending directive optional for that form. gcc/fortran/ChangeLog: * decl.c (gfc_match_end): Add COMP_OMP_STRICTLY_STRUCTURED_BLOCK case together with COMP_BLOCK. * parse.c (parse_omp_structured_block): Change return type to 'gfc_statement', add handling for strictly-structured block case, adjust recursive calls to parse_omp_structured_block. (parse_executable): Adjust calls to parse_omp_structured_block. * parse.h (enum gfc_compile_state): Add COMP_OMP_STRICTLY_STRUCTURED_BLOCK. * trans-openmp.c (gfc_trans_omp_workshare): Add EXEC_BLOCK case handling. gcc/testsuite/ChangeLog: * gfortran.dg/gomp/cancel-1.f90: Adjust testcase. * gfortran.dg/gomp/nesting-3.f90: Adjust testcase. * gfortran.dg/gomp/strictly-structured-block-1.f90: New test. * gfortran.dg/gomp/strictly-structured-block-2.f90: New test. * gfortran.dg/gomp/strictly-structured-block-3.f90: New test. libgomp/ChangeLog: * libgomp.texi (Support of strictly structured blocks in Fortran): Adjust to 'Y'. * testsuite/libgomp.fortran/task-reduction-16.f90: Adjust testcase.
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.
