> Hi,
> Recently the LoopUnrollAndJamPass was made a function pass, and here was
> the motivation for that:
> https://groups.google.com/forum/#!topic/llvm-dev/LF4rUjkVI2g.
> I don't see an obvious reason to keep IRCE as a LoopPass either, so I
> thought folks familiar with the pass could chime in if this seems like the
> right change.
> An additional motivation is the need to either
> preserve BranchProbabilityInfo or have a new instance computed for each
> Loop (D72891 <https://reviews.llvm.org/D72891>). Making IRCE a
> FunctionPass will address this issue.
> Thanks,
> Alina
