gcc/ * tree-vect-loop-manip.c (rename_variables_in_bb): Add argument to allow renaming of PHI arguments on edges incoming from outer loop header, add corresponding check before start PHI iterator. (slpeel_tree_duplicate_loop_to_edge_cfg): Introduce new bool variable DUPLICATE_OUTER_LOOP and set it to true for outer loops with true force_vectorize. Set-up dominator for outer loop too. Pass DUPLICATE_OUTER_LOOP as argument to rename_variables_in_bb. (slpeel_can_duplicate_loop_p): Allow duplicate of outer loop if it was marked with force_vectorize and has restricted cfg. (slpeel_tree_peel_loop_to_edge): Do not rename exit PHI uses in inner loop. * tree-vect-data-refs.c (vect_enhance_data_refs_alignment): Do not do peeling for outer loops. gcc/testsuite/ * gcc.dg/vect/vect-outer-simd-2.c: New test.

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.
