--- Comment #11 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The trunk branch has been updated by Christophe Lyon <cl...@gcc.gnu.org>: https://gcc.gnu.org/g:fdc560aaaedfcf4e3a88379856badd7a153f41cf commit r16-3085-gfdc560aaaedfcf4e3a88379856badd7a153f41cf Author: Christophe Lyon <christophe.l...@linaro.org> Date: Fri Aug 8 12:55:07 2025 +0000 aarch64: libgcc: Honor disable-werror [PR117600] In commit r15-4417-g71c7b446b98aa5, I made -werror mandatory when building libgcc for aarch64. While it achieved its goal (make us fix problems unnoticed so far), there has a been a lot of debate because it couldn't be disabled easily. This patch adds support for --enable-werror/--disable-werror in libgcc, defaulting to --enable-werror for aarch64. Tested on non-bootstrap builds on aarch64-linux-gnu (with -Wno-prio-ctor-dtor removed in order to get an error). libgcc/ChangeLog: PR libgcc/117600 * Makefile.in (WERROR): New. * config/aarch64/t-aarch64: Handle WERROR. * configure: Regenerate. * configure.ac: Add support for --enable-werror.
