The following testcases ICE because fold_array_ctor_reference in the RAW_DATA_CST handling just return build_int_cst without actually checking that if type is non-NULL, TREE_TYPE (val) is uselessly convertible to it. By falling through the code after it without *suboff += we get everything we need, the two if conditionals will never be true (we've already checked that size == BITS_PER_UNIT and so can't be 0, and val will be INTEGER_CST), but it will do the important fold_ctor_reference call which will deal with type incompatibilities. 2024-12-28 Jakub Jelinek <jakub@redhat.com> PR tree-optimization/118207 * gimple-fold.cc (fold_array_ctor_reference): For RAW_DATA_CST, just set val to build_int_cst and fall through to the normal element handling code instead of returning build_int_cst right away. * gcc.dg/pr118207.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.
