I don't regret using LLVM at all. I regret using the instruction decoding features in LLVM. if I could do it again (and someone younger, smarter, and better looking than me is) I would combine the LLVM IR with the XED instruction decoder. we would still emit the semantics of the instructions as LLVM, but we would use XED to figure out which instruction we were decoding.
