The following removes the fixup we apply to pattern stmt operands before code generating vector epilogues. This isn't necessary anymore since the SLP graph now exclusively records the data flow. Similarly fixing up of SSA references inside DR_REF of gather/scatter isn't necessary since we now record the analysis result and avoid re-doing it during transform. What we still need to keep is the adjustment of the actual pointers to gimple stmts from stmt_vec_info and the back-reference from the DRs. * tree-vect-loop.cc (update_epilogue_loop_vinfo): Remove fixing up pattern stmt operands and gather/scatter DR_REFs. (find_in_mapping): Remove.
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.
