(c_parser_oacc_clause_tile): Disallow collapse. Fix parsing and semantic checking. * c-parser.c (c_parser_omp_for_loop): Accept tiling constructs. gcc/cp/ * parser.c (cp_parser_oacc_clause_tile): Disallow collapse. Fix parsing. Parse constant expression. Remove semantic checking. (cp_parser_omp_clause_collapse): Disallow tile. (cp_parser_omp_for_loop): Deal with tile clause. Don't emit a parse error about missing for after already emitting one. Use more conventional for idiom for unbounded loop. * pt.c (tsubst_omp_clauses): Handle OMP_CLAUSE_TILE. * semantics.c (finish_omp_clauses): Correct TILE semantic check. (finish_omp_for): Deal with tile clause. gcc/fortran/ * openmp.c (resolve_omp_clauses): Error on directives containing both tile and collapse clauses. (resolve_oacc_loop_blocks): Represent '*' tile arguments as zero. * trans-openmp.c (gfc_trans_omp_do): Lower tiled loops like collapsed loops. gcc/testsuite/ * c-c++-common/goacc/combined-directives.c: Remove xfail. * c-c++-common/goacc/loop-auto-1.c: Adjust and add additional case. * c-c++-common/goacc/loop-auto-2.c: New. * c-c++-common/goacc/tile.c: Include stdbool, fix expected errors. * c-c++-common/goacc/tile-2.c: New. * g++.dg/goacc/template.C: Test tile subst. Adjust erroneous uses. * g++.dg/goacc/tile-1.C: New, check tile subst. * gcc.dg/goacc/loop-processing-1.c: Adjust dg-final pattern. * gfortran.dg/goacc/combined-directives.f90: Remove xfail. * gfortran.dg/goacc/tile-1.f90: New test. * gfortran.dg/goacc/tile-2.f90: New test. * gfortran.dg/goacc/tile-lowering.f95: New test. libgomp/ * testsuite/libgomp.oacc-c-c++-common/tile-1.c: New. * testsuite/libgomp.oacc-c-c++-common/loop-auto-1.c: Adjust and add additional case. * testsuite/libgomp.oacc-c-c++-common/vprop.c: XFAIL under "openacc_nvidia_accel_selected". * libgomp.oacc-fortran/nested-function-1.f90 (test2): Add num_workers(8) clause.

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.
