[llvm-dev] RFC: token arguments and operand bundles

I think we do want to support different regions of FP safety through inlining and other means, but I otherwise agree with your conclusion that tokens as I was using them are not a good fit. We should be able to handle different regions by using different constraint arguments (in whatever form).

Based on what I've read in this thread, it doesn't seem like tokens are a good fit here. If in the future we want to establish different regions of FP safety (i.e. inlining functions with different FP safety settings), then it might make sense to start using tokens.
