I was going to look at the encoding for nuw (OBO_NO_UNSIGNED_WRAP) and follow how it is encoded/decoded in the bitcode. I would then specify some kind of fast-math enum and encode it in a similar fashion. After I go down this path a little more I might be able to give you a more intelligent answer. Thanks! > -Chris >

I think I missed what problem we're trying to solve here. I'm looking at implementing the bitcode now. I have code to successfully read and write out the LLVM IR textual formal (LLParser, etc) and set the corresponding SubclassOptionalData bits. Looking at LLVMBitCodes.h, I'm seeing where these bits reside in the bitcode, so I believe that things should be pretty straight-forward from
