Please add `unless(isInTemplateInstantiation` as the first thing inside `cxxOperatorCallExpr` to exclude matches from inside template instantiations. We don't care about instantiations, only template declarations, because the instantiation may diagnose an issue from a substituted type, that is not a `string_view` in another instantiation. https://github.com/llvm/llvm-project/pull/120055 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
