--- Comment #1 from Filip Pizlo <fpizlo at apple.com> ---
When and if we implement a fix that allows the peephole detection to "skip" the MovHint, we should check how much of a speed-up it is.

If it is not a speed-up, then instead of writing a patch that extends the peephole to skip MovHint, we should write a patch that removes all code for those peepholes that are currently dead because of the MovHint.  That peephole code is a pain to maintain and it's possible that it buys us nothing.
