[PATCH] D130895: [RISCV] Make VL choosing for a splat-like VMV based on its users

[Philip Reames via Phabricator via llvm-commits]

reames added a comment.

I don't think there's much to say here.  My prior point still stands.  I find your proposed reading of the specification unconvincing.  The optimization as proposed is unsound.

I am not particularly interested in this optimization.  Unless you have a strong motivation to pursue this - in which case, please explain why - I'd suggest we abandon this patch and move on with our lives.
