Calculate block exit info upfront, and then any SSA_NAME which is never used in an outgoing range calculation is a pure global and can bypass the on-entry cache. PR tree-optimization/98174 * gimple-range-cache.cc (ranger_cache::ssa_range_in_bb): Only push poor values to be examined if it isn't a pure global. (ranger_cache::block_range): Don't process pure globals. (ranger_cache::fill_block_cache): Adjust has_edge_range call. * gimple-range-gori.cc (gori_map::all_outgoing): New bitmap. (gori_map::gori_map): Allocate all_outgoing. (gori_map::is_export_p): No specified BB returns global context. (gori_map::calculate_gori): Accumulate each block into global. (gori_compute::gori_compute): Preprocess each block for exports. (gori_compute::has_edge_range_p): No edge returns global context. * gimple-range-gori.h (has_edge_range_p): Provide default parameter.
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.
