Rangers PHI analyzer currently only allows a single initializer to a group. This patch changes that to use an inialization range, which is cumulative of all integer constants, plus a single symbolic value. There is no other change to group functionality. This patch also changes the way PHI groups are printed so they show up in the listing as they are encountered, rather than as a list at the end. It was more difficult to see what was going on previously. PR tree-optimization/110918 - Initialize with range instead of a tree. gcc/ * gimple-range-fold.cc (fold_using_range::range_of_phi): Tweak output. * gimple-range-phi.cc (phi_group::phi_group): Remove unused members. Initialize using a range instead of value and edge. (phi_group::calculate_using_modifier): Use initializer value and process for relations after trying for iteration convergence. (phi_group::refine_using_relation): Use initializer range. (phi_group::dump): Rework the dump output. (phi_analyzer::process_phi): Allow multiple constant initilizers.

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.
