[lenary]

This didn't happen before because it is used by vendored isl code in Polly, as this diff shows. I'm not sure the status of updating that code, but the (external) author was informed a while ago about needing to update. I don't know who maintains Polly and whether they accept direct changes to vendored code or whether changes have to go upstream first.

The changes have been made upstream to isl: https://repo.or.cz/isl.git/commitdiff/7ffab9c411283f3e22d39940dd8f57e9ccf497cb?hp=5d5b77e2369434a95d2d66824409b46d2155ba5b

Thanks! According to git log -- polly, it looks like various people have been making search-n-replace-type changes to polly in our repository.
