MaskRay added a comment. From https://gcc.gnu.org/ml/gcc/2020-02/msg00116.html
> We discussed this on IRC in #gcc. There was no motivation to change GCC. The > platform that wants to avoid the libatomic dependency doesn't use GCC anyway. > Relying on not getting the libatomic dependency seems fragile (it only works > for a specific codebase, and if some other is_lock_free check is added to the > codebase, the libatomic dependency will return anyway). So they will not extend the interface. Clang has `getMaxAtomicPromoteWidth()`. Do we need the extension? I'm happy with either way.
