Add modes to range_from_dom such that we can simply query, or adjust the cache and deal with multiple predecessor blocks. * gimple-range-cache.cc (ranger_cache::ranger_cache): Start with worlist truncated. (ranger_cache::entry_range): Add rfd_mode parameter. (ranger_cache::exit_range): Ditto. (ranger_cache::edge_range): New. Incorporate from range_on_edge. (ranger_cache::range_of_expr): Adjust call to entry_range. (ranger_cache::range_on_edge): Split to edge_range and call. (ranger_cache::fill_block_cache): Always invoke range_from_dom. (ranger_cache::range_from_dom): Make reentrant, add search mode, handle mutiple predecessors. (ranger_cache::update_to_nonnull): Adjust call to exit_range. * gimple-range-cache.h (ranger_cache): Add enum rfd_mode. Adjust prototypes. |

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.
