Is this the same as https://reviews.llvm.org/D136244? Looks like there are two tickets for the same issue.

They both solve it differently. D136244 <https://reviews.llvm.org/D136244> looks like it is more general - handling more cases then just bcmp. But this might optimize larger bcmp's? I think I would expect them to become a series of `cmp;ccmp;ccmp;ccmp` when optimized properly though.
