## Summary build configuration `mps3-an547:clang` with arm [clang](https://github.com/arm/arm-toolchain/releases/tag/release-21.1.1-ATfE), and enable config `CONFIG_FORTIFY_SOURCE=3`, will meet two errors: 1st error message: `error: compiler version less than 12 does not support dynamic object size` Reason: the clang compiler has also defined `__GNUC__`, which can't be used to decide the compiler version. And the version used to decide whether the builtin function `__builtin_dynamic_object_size` exist is not correct. 2nd error: `use of undeclared identifier '__builtin_va_arg_pack'` Reason: clang does not have builtin function `__builtin_va_arg_pack` ## Impact clang fortify ## Testing build configuration `mps3-an547:clang` with config `CONFIG_FORTIFY_SOURCE=3` enabled. -- This is an automated message from the Apache Git Service.
