The following adds missing vector support checks to abs producing match.pd patterns. The g++.dg/absvect.C shows that we previously then lowered this to non-vector unless you add -msse4 on x86_64 at least. PR tree-optimization/124555 * match.pd ((A - B) >=/> 0 ? (A - B) : (B - A) -> abs (A - B)): Guard the vector case with target_supports_op_p checks. ((A - B) <=/< 0 ? (A - B) : (B - A) -> -abs (A - B)): Likewise. ((type)A >=/> 0 ? A : -A -> abs (A)): Likewise. ((type)A <=/< 0 ? A : -A -> -abs (A)): Likewise. * gcc.dg/torture/pr124555.c: New testcase. * g++.dg/absvect.C: Restrict dump scan to x86-64 and force -msse4 there.
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.
