--- Comment #7 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:a107b01da42b2f2303ffe53df5ea4a796f40597d commit r16-3035-ga107b01da42b2f2303ffe53df5ea4a796f40597d Author: Jakub Jelinek <ja...@redhat.com> Date: Wed Aug 6 11:30:48 2025 +0200 libgcc: Remove useless forward declaration [PR121397] aarch64 for some strange reason unconditionally enables -Werror for libgcc building and this particular file for some strange reason contains a useless static forward declaration of a function only defined in the #if defined __sun__ && defined __svr4__ block and not otherwise (with __attribute__((constructor))). And we warn (with -Werror error) in the non-__sun__/__svr4__ case because it declares a static function that is never defined. The forward declaration makes no sense to me, for static functions forward declarations shouldn't be needed even for -Wstrict-prototypes, and AFAIK we don't warn on static __attribute__((constructor)) void foo (void) {} being unused. And the function isn't used before being defined. So, the following patch just removes the forward declaration. 2025-08-06 Jakub Jelinek <ja...@redhat.com> PR libgcc/121397 * enable-execute-stack-mprotect.c (check_enabling): Remove useless forward declaration.
