--- Comment #3 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The master branch has been updated by Christophe Lyon <cl...@gcc.gnu.org>: https://gcc.gnu.org/g:13a966d56fe60418cf88c11cbd45797f1cbfed5f commit r15-5233-g13a966d56fe60418cf88c11cbd45797f1cbfed5f Author: Christophe Lyon <christophe.l...@linaro.org> Date: Wed Nov 13 21:20:13 2024 +0000 libgcc: Fix COPY_ARG_VAL initializer (PR 117537) We recently forced -Werror when building libgcc for aarch64, to make sure we'd catch and fix the kind of problem described in the PR. In this case, when building for aarch64_be (so, big endian), gcc emits this warning/error: libgcc/config/libbid/bid_conf.h:847:25: error: missing braces around initializer [-Werror=missing-braces] 847 | UINT128 arg_name={ bid_##arg_name.w[1], bid_##arg_name.w[0]}; libgcc/config/libbid/bid_conf.h:871:8: note: in expansion of macro 'COPY_ARG_VAL' 871 | COPY_ARG_VAL(arg_name) This patch fixes the problem by adding curly braces around the initializer for COPY_ARG_VAL in the big endian case. It seems that COPY_ARG_REF (just above COPY_ARG_VAL) has a similar issue, but DECIMAL_CALL_BY_REFERENCE seems always defined to 0, so COPY_ARG_REF is never used. The patch fixes it too, though. libgcc/config/libbid/ChangeLog: PR libgcc/117537 * bid_conf.h (COPY_ARG_REF): Fix initializer. (COPY_ARG_VAL): Likewise.
