2017-09-21 Richard Biener <rguenther@suse.de> * graphite-isl-ast-to-gimple.c (translate_pending_phi_nodes): Verify both BBs contain loop PHI nodes before dispatching to copy_loop_phi_args. (graphite_regenerate_ast_isl): Do not recompute dominators, do not verify three times. Restructure for clarity. * graphite-scop-detection.c (same_close_phi_node, remove_duplicate_close_phi, make_close_phi_nodes_unique, defined_in_loop_p, canonicalize_loop_closed_ssa, canonicalize_loop_closed_ssa_form): Simplify, remove excess checking and SSA rewrite, move to ... * graphite.c: ... here. Include ssa.h and tree-ssa-loop-manip.h. (graphite_initialize): Do not pass in ctx, do not reset the SCEV cache, compute only dominators. (graphite_transform_loops): Allocate ISL ctx after graphite_initialize. Call canonicalize_loop_closed_ssa_form. Maintain post-dominators only around build_scops. * sese.c (if_region_set_false_region): Make static. Free and recompute dominators. (move_sese_in_condition): Assert we don't get called with post-dominators computed. * sese.h (if_region_set_false_region): Remove. From-SVN: r253090
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.
