The PR shows that code generation ends up pessimized by the new canonicalization rules that end up nailing do-not-care elements to specific values making it hard to generate good code later. The temporary solution is to avoid this for the cases we also obviously know the canonicalization will create more GIMPLE stmts than before. 2020-02-04 Richard Biener <rguenther@suse.de> PR tree-optimization/92819 * tree-ssa-forwprop.c (simplify_vector_constructor): Avoid generating more stmts than before. * gcc.target/i386/pr92819.c: New testcase. * gcc.target/i386/pr92803.c: Adjust. |

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.
