The intrin names in current ACE documentation are not following naming convention. They should be changed and should not be referenced. When implementing, GCC have synced with LLVM folks on those names and we have reached the agreement since there are some special cases in ACE. Please make sure the names we both have are aligned or it will lead to issues.
