Andrew's patch for this PR103254 papered over some underlying performance issues in the path solver that I'd like to address. We are currently solving the SSA's defined in the current block in bitmap order, which amounts to random order for all purposes. This is causing unnecessary recursion in gori. This patch changes the order to gimple order, thus solving dependencies before uses. There is no change in threadable paths with this change. Tested on x86-64 & ppc64le Linux. gcc/ChangeLog: PR tree-optimization/103254 * gimple-range-path.cc (path_range_query::compute_ranges_defined): New (path_range_query::compute_ranges_in_block): Move to compute_ranges_defined. * gimple-range-path.h (compute_ranges_defined): New. |

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.
