The gimple_parm_array_size function comment talks about pointe parameters but doesn't actually verify it, it checks whether an attribute is present on the function and then just uses TREE_TYPE (TREE_TYPE (var)) which assumes a pointer type (or in theory could work for ARRAY_TYPE but c-family languages which only have that attribute will never have ARRAY_TYPE parameters; and for VECTOR_TYPE/COMPLEX_TYPE it would mean something quite different). So, this patch punts early if var doesn't have pointer/reference type. 2022-05-19 Jakub Jelinek <jakub@redhat.com> PR c/105635 * pointer-query.cc (gimple_parm_array_size): Return NULL if var doesn't have pointer or reference type. * gcc.dg/pr105635.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.
