The following fixes SLP vectorization of stores that were pattern recognized. Since in SLP vectorization pattern analysis happens after dataref group analysis we have to adjust the groups with the pattern stmts. This has some effects down the pipeline and exposes cases where we looked at the wrong pattern/non-pattern stmts. 2020-11-05 Richard Biener <rguenther@suse.de> * tree-vect-data-refs.c (vect_slp_analyze_node_dependences): Use the original stmts. (vect_slp_analyze_node_alignment): Use the pattern stmt. * tree-vect-slp.c (vect_fixup_store_groups_with_patterns): New function. (vect_slp_analyze_bb_1): Call it. * gcc.dg/vect/bb-slp-69.c: New testcase.

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.
