Mark mentioned in the PR further 2 simplifications that also ICE with complex types. For these, eventually (but IMO GCC 13 materials) we could support it for vector types if it would be uniform vector constants. Currently integer_pow2p is true only for INTEGER_CSTs and COMPLEX_CSTs and we can't use bit_and etc. for complex type. 2022-02-25 Jakub Jelinek <jakub@redhat.com> Marc Glisse <marc.glisse@inria.fr> PR tree-optimization/104675 * match.pd (t * 2U / 2 -> t & (~0 / 2), t / 2U * 2 -> t & ~1): Restrict simplifications to INTEGRAL_TYPE_P. * gcc.dg/pr104675-3.c : New test. |

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.
