-// This class parses the Schedule.td file and produces an API that can be used
-// to reason about whether an instruction can be added to a packet on a VLIW
-// architecture. The class internally generates a deterministic finite
-// automaton (DFA) that models all possible mappings of machine instructions
-// to functional units as instructions are added to a packet.
