The following fixes missed optimizations due to the strange way we split stores in BB vectorization. The solution is to split at the failure boundary and not re-align that to the initial piece chosen vector size. Also re-analyze any larger matching rest. 2020-10-28 Richard Biener <rguenther@suse.de> * tree-vect-slp.c (vect_build_slp_instance): Split the store group at the failure boundary and also re-analyze a large enough matching rest. * gcc.dg/vect/bb-slp-68.c: New testcase. |

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.
