I don't think we have precedent for disabling a warning in a SFINAE context. We do suppress warnings produced while substituting into a function template specialization during deduction if we end up not selecting that overload, but I don't think we have something analogous for concepts, and it's not clear that that would help here, given that the warning would be produced in the case where the concept check *succeeds*. You can check if you're in an unevaluated context with `Sema::isUnevaluatedContext`. https://github.com/llvm/llvm-project/pull/141133 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
