--- Comment #1 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:09ef9756f22a8c4143c6b8d3afcddc72fb700c76 commit r15-5348-g09ef9756f22a8c4143c6b8d3afcddc72fb700c76 Author: Jakub Jelinek <ja...@redhat.com> Date: Sat Nov 16 17:04:38 2024 +0100 libgcc: Fix a warning/error in libgcc2.c [PR117624] Since the switch to -std=gnu23 by default, float.h (included from tsystem.h) defines INFINITY macro (to __builtin_inff ()), which now results in a warning when compiling libgcc2.c which defines it to something else (and, worse aarch64 compiles it with -Werror and build fails). libgcc2.c asserts INFINITY has the expected type which depends on the macros with which libgcc2.c is being compiled, so guarding the define with #ifndef INFINITY wouldn't work. So this patch instead #undefs the macro before defining it. 2024-11-16 Jakub Jelinek <ja...@redhat.com> PR libgcc/117624 * libgcc2.c (INFINITY): Add #undef before #define.
