Hi, I'm trying to get the DFAPacketizer to work for my target but with any instruction I get the 'Assertion `CachedTable.count(StateTrans) != 0' failed' error and it crashes out before packeting a single instruction. I have a *GenDFAPacketizer.inc file and my packetizer pass checks that the table is not empty before proceeding. I also have a schedule file with my functional units and itineraries listed. Can anyone think of...

Do you reserve some resource without verification? Note that reserveResources() should be called iff canReserveResources() is true (the call order is important here) even for the trivial case (0 instruct...

For some reason on my VLIW target DFAPacketizer fails at assert(CachedTable.count(StateTrans) != 0); in the following function: // reserveResources - Reserve the resources occupied by a MCInstrDesc and // change the current state to reflect that change. void DFAPacketizer::reserveResources(const llvm::MCInstrDesc *MID) { unsigned InsnClass = MID->getSchedClass(); const llvm::Instr...

FuncUnits = 0 CurrentState = 0 StateTrans = {first = 0, second = 0} I understand that there is something wrong with the state machine but I can't figure out what exactly. My scheduler description is the same as for Hexagon or R600. So why would DFA would look any different for my target? What could be the problem? -- R -------------...
