As we can't cope with removed SLP instances during analysis there's no point in doing that or even continuing analysis of SLP instances after a failure. The following makes us abort early. * tree-vect-slp.cc (vect_slp_analyze_operations): When doing loop analysis fail after the first failed SLP instance. Only remove instances when doing BB vectorization. * tree-vect-loop.cc (vect_analyze_loop_2): Check whether vect_slp_analyze_operations failed instead of checking the number of SLP instances remaining. |

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.
