Delay omp_max_vf call until after the host and device compilers have diverged so that the max_vf value can be tuned exactly right on both variants. This change means that the ompdevlow pass must be enabled for functions that use OpenMP directives with both "simd" and "schedule" enabled. gcc/ChangeLog: * internal-fn.cc (expand_GOMP_MAX_VF): New function. * internal-fn.def (GOMP_MAX_VF): New internal function. * omp-expand.cc (omp_adjust_chunk_size): Emit IFN_GOMP_MAX_VF when called in offload context, otherwise assume host context. * omp-offload.cc (execute_omp_device_lower): Expand IFN_GOMP_MAX_VF. |

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.
