GCC modified for the FreeChainXenon project
9f9b3d6732
This patch introduces enumerators to represent trait-set names and trait names, which makes it easier to use tables to control other behavior and for switch statements to dispatch on the tags. The tags are stored in the same place in the TREE_LIST structure (OMP_TSS_ID or OMP_TS_ID) and are encoded there as integer constants. gcc/ChangeLog * omp-selectors.h: New file. * omp-general.h: Include omp-selectors.h.

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.
