--- Comment #5 from Sanjay Patel <spatel+llvm at rotateright.com> ---
Improve memop merging and use rotate:
https://reviews.llvm.org/rG2df46a574387
There are possible enhancements/refinements to that functionality, but I think
we should have motivating benchmarks before trying to chase those (it's not
clear to me that using rotates is always a win).

Optionally convert to bswap:
https://reviews.llvm.org/rG8779b114109d
If the rotate with memory op has better perf and/or optimizing for size, please
file a separate bug.
