llvm dev - Nov 2015 - HexagonPacketizerList and FoundSequentialDependence

HexagonPacketizerList has a boolean member called
FoundSequentialDependence. I've been staring at the code in
HexagonVLIWPacketizer.cpp for quite some time but I can't figure out what
exactly it is doing and what is meant by a sequential dependence. Would
anyone be able to explain it?

Any help is appreciated.
