This patch adds middle-end support for the `dispatch` construct and the `adjust_args` clause. The heavy lifting is done in `gimplify_omp_dispatch` and `gimplify_call_expr` respectively. For `adjust_args`, this mostly consists in emitting a call to `omp_get_mapped_ptr` for the adequate device. For dispatch, the following steps are performed: * Handle the device clause, if any: set the default-device ICV at the top of the dispatch region and restore its previous value at the end. * Handle novariants and nocontext clauses, if any. Evaluate compile-time constants and select a variant, if possible. Otherwise, emit code to handle all possible cases at run time. gcc/ChangeLog: * builtins.cc (builtin_fnspec): Handle BUILT_IN_OMP_GET_MAPPED_PTR. * gimple-low.cc (lower_stmt): Handle GIMPLE_OMP_DISPATCH. * gimple-pretty-print.cc (dump_gimple_omp_dispatch): New function.

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.
