2015-12-14 Richard Biener <rguenther@suse.de> PR tree-optimization/68852 * tree-vectorizer.h (struct _slp_tree): Add def_type member. (SLP_TREE_DEF_TYPE): New accessor. * tree-vect-stmts.c (vect_is_simple_use): Remove BB vectorization hack. * tree-vect-slp.c (vect_create_new_slp_node): Initialize SLP_TREE_DEF_TYPE. (vect_build_slp_tree): When a node is to be built up from scalars do not push a NULL as child but instead set its def_type to vect_external_def. (vect_analyze_slp_cost_1): Check for child def-type instead of NULL. (vect_detect_hybrid_slp_stmts): Likewise. (vect_bb_slp_scalar_cost): Likewise. (vect_get_slp_defs): Likewise. (vect_slp_analyze_node_operations): Likewise. Before processing node push the children def-types to the underlying stmts vinfo and restore it afterwards. (vect_schedule_slp_instance): Likewise. (vect_slp_analyze_bb_1): Do not mark stmts not in SLP instances as not vectorizable. * g++.dg/torture/pr68852.C: New testcase. From-SVN: r231619 |

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.
