Rebased

Fixed ninja target names in README

Added README

Cleaned up code and refined Python driver script

Modified Python script.

Alphabetized opcode enums in .proto files, modified Python script, and added comment to handle_asm.cpp.

Combined protobuf for RV64 and RV32 base ISAs into single protobuf for RISC-V fuzzer tool.

Removed default path to GNU objdump (/prj/.../) from example_mcfuzz script

Fixed according to Mandeep's comments

Abandoning revision because tool has been moved to llvm/tools from clang/tools, as of this patch: https://reviews.llvm.org/D51144

Fixed error in Python script

Updated with pseudoinstructions added to the Protobuf

Patch got messed up, fixing it now.

Added missing instructions to rv32i.proto and rv32c.proto

Cleaned up proto_to_asm, simplified grammar to have fewer messages and be more easily extensible

Rebased patch and added fuzzer support for more extensions (m,c)

Added Load instructions to fuzzer's Protobuf representation of the RV32I ISA (rv32i_asm.proto and proto_to_asm_rv32i.cpp)

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.

Reverting

Fixed hardcoded paths in cmake/modules/ProtobufMutatorMC.cmake, cleaned up naming in asm_proto.proto, updated README, and reverted changes in cmake/modules/ProtobufMutator.cmake
