Hi Jocelyn. What should I be referring to as the base of this patch? e.g. D49521 doesn't contain proto_to_asm_rv32i.cpp?

This patch adds two new files: proto_to_asm_rv32i.cpp and rv32i_asm.proto. These files add to proto_to_asm.cpp and asm_proto.proto from the previous patch (https://reviews.llvm.org/D49521), which we chose to leave untouched so as to preserve the simpler example grammar that only contains the add and sub instructions.

But the patch as upload modifies a few lines of proto_to_asm_rv32i.cpp rather than adding it from scratch, which is why I wondered if there's an intermediate patch or a problem with the diff generation.
