--- Comment #2 from Yichao Yu <yyc1992 at gmail dot com> --- As an update, it seems that the llvm trunk recently switched to using `__atomic_*` function call for int128 on all platforms (that I can test anyway). I'm not sure how that decision is made or if there's any communication with GCC but IMHO it would be nice to agree on using the atomic instruction on aarch64 as long as it provides all the necessary ones.
