--- Comment #7 from GCC Commits <cvs-commit at gcc dot gnu.org> --- The releases/gcc-11 branch has been updated by Kyrylo Tkachov <ktkac...@gcc.gnu.org>: https://gcc.gnu.org/g:d32cfe3352f3863325f8452e83400063b1e71e5b commit r11-11564-gd32cfe3352f3863325f8452e83400063b1e71e5b Author: Kyrylo Tkachov <ktkac...@nvidia.com> Date: Thu Jun 27 16:10:41 2024 +0530 aarch64: PR target/115457 Implement missing __ARM_FEATURE_BF16 macro The ACLE asks the user to test for __ARM_FEATURE_BF16 before using the <arm_bf16.h> header but GCC doesn't set this up. LLVM does, so this is an inconsistency between the compilers. This patch enables that macro for TARGET_BF16_FP. Bootstrapped and tested on aarch64-none-linux-gnu. gcc/ PR target/115457 * config/aarch64/aarch64-c.c (aarch64_update_cpp_builtins): Define __ARM_FEATURE_BF16 for TARGET_BF16_FP. gcc/testsuite/ PR target/115457 * gcc.target/aarch64/acle/bf16_feature.c: New test.
