Roman Lebedev 92ce5b3319 [llvm-exegesis] Exploring X86::OperandType::OPERAND_COND_CODE ... Summary: Currently, we only have nice exploration for LEA instruction, while for the rest, we rely on `randomizeUnsetVariables()` to sometimes generate something interesting. While that works, it isn't very reliable in coverage :) Here, i'm making an assumption that while we may want to explore multi-instruction configs, we are most interested in the characteristics of the main instruction we were asked about. Which we can do, by taking the existing `randomizeMCOperand()`, and turning it on it's head - instead of relying on it to randomly fill one of the interesting values, let's pregenerate all the possible interesting values for the variable, and then generate as much `InstructionTemplate` combinations of these possible values for variables as needed/possible. Of course, that requires invasive changes to no longer pass just the naked `Instruction`, but sometimes partially filled `InstructionTemplate`. As it can be seen from the test, this allows us to explore `X86::OperandType::OPERAND_COND_CODE` for instructions that take such an operand. I'm hoping this will greatly simplify exploration.
