The following guards dse_classify_store with the same condition as the DSE pass does - availability of a virtual definition. For the PR we run into the fortran frontend generating a clobber for a FUNCTION_DECL lhs which is ignored by the operand scanner and has no virtual operands assigned. Apart from fixing the frontend the following fixes the ICE by adjusting if-conversion. 2022-03-22 Richard Biener <rguenther@suse.de> PR tree-optimization/105012 * tree-if-conv.cc (ifcvt_local_dce): Only call dse_classify_store when we have a VDEF. |

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.
