            Bug ID: 37498
           Summary: [llvm-exegesis] Support opcode lists for benchmarking
           Product: new-bugs
           Version: unspecified
          Hardware: PC
                OS: Windows NT
            Status: NEW

It'd be very helpful if we could provide a list of opcodes and have the output
generated for each of them:

e.g.
llvm-exegesis -benchmark-mode=latency
-opcode-name=PMULLDrr,VPMULLDrr,VPMULLDYrr

A comma separated list would be preferred but allowing repeated
-opcode-name=XXXX options would be acceptable:

e.g.
llvm-exegesis -benchmark-mode=latency -opcode-name=PMULLDrr
-opcode-name=VPMULLDrr -opcode-name=VPMULLDYrr
