llvm dev - Apr 2020 - Using AntiDepBreaker outside of PostRAListScheduler

Hi,

Is there any reason why AntiDepBreaker cannot be used by a scheduler other
than PostRAListScheduler? From looking at the code I don't see any obvious
dependency.

I would like to use the anti dependency breaker in a target specific postRA
scheduler. Does anybody have an objection to making AntiDepBreaker.h public
rather than keeping it as internal in lib/Codegen? I see that it got moved
there from the include directory many years ago but I don't see any
explanation for this change.
