User errors will have been reported before this. I think the expectation is that we shouldn't hit this failure, but while the CIR code is still partially implemented we probably will. For now, this is kind of acting as a backstop against failures. So, returning to your original question, I think, yes, this is "mostly for debugging purposes while we get stuff up and running." https://github.com/llvm/llvm-project/pull/124650 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
