--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Jakub Jelinek <ja...@gcc.gnu.org>: https://gcc.gnu.org/g:5fd1c0c1b6968d55e3f997d67a4c149edf20c012 commit r15-4553-g5fd1c0c1b6968d55e3f997d67a4c149edf20c012 Author: Jakub Jelinek <ja...@redhat.com> Date: Tue Oct 22 20:30:41 2024 +0200 c-family: Fix up -Wsizeof-pointer-memaccess ICEs [PR117230] In the following testcases, we ICE on all 4 function calls. The problem is using TYPE_PRECISION on vector types (but guess it would be similarly problematic on structures/unions/arrays). The test only differentiates between suggestion what to do, whether to supply explicit size because sizeof (*p) for {,{,un}signed }char *p is not very likely what the user want, or dereferencing the pointer, so I think limiting that suggestion to integral types is ok. 2024-10-22 Jakub Jelinek <ja...@redhat.com> PR c/117230 * c-warn.cc (sizeof_pointer_memaccess_warning): Only compare TYPE_PRECISION of TREE_TYPE (type) to precision of char if TREE_TYPE (type) is integral type. * c-c++-common/Wsizeof-pointer-memaccess5.c: New test.
