[llvm-dev] Hexagon, DFAPacketzier and dependency pruning

DFAPacketizer has a virtual method isLegalToPruneDependencies(). I looked
at  the Hexagon code and but wasn't unable to understand the details
(unfortunately as of now, I'm not well versed in the Hexagon architecture).
Would anyone be able to shed light on what is dependency pruning and how it
should be used?

Any help is appreciated.
