[PATCH] D137440: [RISCV][llvm-mca] Use LMUL Instruments to provide more accurate reports on RISCV

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

Longer term, I really do think we need to be able to parse LMUL from vsetvli instructions, and have that influence scheduling of following instructions.  I want to be able to take a program trace, and run it through llvm-mca without having to parse the trace and add annotations before doing so.  Having said that, I have zero objection to the annotation mechanism being proposed here, and think it is useful.  For the actual review, I'll defer to already active reviewers who are a lot more familiar with the internals of MCA that I am.  :)
