Yes, that's what I meant with "This implementation is overly pessimistic for one-as syncscopes: one-as acquire operations that don't affect the global addrspace could be ignored for the noclobber analysis. Improving this is left for a follow-up PR." in the PR description. I will look into that next. AFAIK that's the only spot where we currently use MMRAs.
