My/Kees' earlier patches adjusted -Wunterminated-string-initialization warning so that it doesn't warn about initializers of nonstring decls and that nonstring attribute is allowed on multi-dimensional arrays. Unfortunately as this testcase shows, we still warn about initializers of multi-dimensional array nonstring decls. The problem is that in that case field passed to output_init_element is actually INTEGER_CST, index into the array. For RECORD_OR_UNION_TYPE_P (constructor_type) field is a FIELD_DECL which we want to use, but otherwise (in arrays) IMHO we want to use constructor_fields (which is the innermost FIELD_DECL whose part is being initialized), or - if that is NULL - constructor_decl, the whole decl being initialized with multi-dimensional array type. 2025-03-11 Jakub Jelinek <jakub@redhat.com> PR c/117178 * c-typeck.cc (output_init_element): Pass field to digest_init only for record/union types, otherwise pass constructor_fields if non-NULL and constructor_decl if constructor_fields is NULL. * gcc.dg/Wunterminated-string-initialization-2.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.
