Ill add that as a todo. Although maybe indicative we want to the flag to be based on the exact intrin as opposed to `isPointer` as different intrins may have different preference. For `@llvm.ptrmask` for example. we can easily represent the most common constant (`null`) by just zeroing the mask so there isn't much benefit to constant return. But for other intrins might be different. https://github.com/llvm/llvm-project/pull/67166 _______________________________________________ cfe-commits mailing list cfe-commits@lists.llvm.org https://lists.llvm.org/cgi-bin/mailman/listinfo/cfe-commits
