PR tree-optimization/37027 * tree-vectorizer.h (struct _loop_vec_info): Add new field reductions and macro to access it. (vectorizable_reduction): Add argument. (vect_get_slp_defs): Likewise. * tree-vect-loop.c (vect_analyze_scalar_cycles_1): Collect reduction statements for possible use in SLP. (new_loop_vec_info): Initialize LOOP_VINFO_REDUCTIONS. (destroy_loop_vec_info): Free LOOP_VINFO_REDUCTIONS. (vect_create_epilog_for_reduction): Handle SLP. Modify documentation, add new argument. (vectorizable_reduction): Likewise. * tree-vect-stmts.c (vect_get_vec_defs): Update call to vect_get_slp_defs. (vectorizable_type_demotion, vectorizable_type_promotion, vectorizable_store): Likewise. (vect_analyze_stmt): Update call to vectorizable_reduction. (vect_transform_stmt): Likewise. * tree-vect-slp.c (vect_get_and_check_slp_defs): Handle reduction. (vect_build_slp_tree): Fix indentation. Check that there are no loads from different interleaving chains in same node. (vect_slp_rearrange_stmts): New function. (vect_supported_load_permutation_p): Allow load permutations for reductions. Call vect_slp_rearrange_stmts() to rearrange statements inside SLP nodes if necessary. (vect_analyze_slp_instance): Handle reductions. (vect_analyze_slp): Try to build SLP instances originating from groups of reductions. (vect_detect_hybrid_slp_stmts): Skip reduction statements. (vect_get_constant_vectors): Create initial vectors for reductions according to reduction code. Add new argument. (vect_get_slp_defs): Add new argument, pass it to vect_get_constant_vectors. (vect_schedule_slp_instance): Remove SLP tree root statements. From-SVN: r158506 |

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.
