a bundle with one instruction
...ket with
one instruction? Current code to end packet doesn't handle this case:
// endPacket - End the current packet, bundle packet instructions and reset
// DFA state.
void VLIWPacketizerList::endPacket(MachineBasicBlock *MBB,
MachineInstr *MI) {
if (CurrentPacketMIs.size() > 1) {
MachineInstr *MIFirst = CurrentPacketMIs.front();
finalizeBundle(*MBB, MIFirst, MI);
}
CurrentPacketMIs.clear();
ResourceTracker->clearResources();
}
My initial idea was to simply add a NOP instruction to the
CurrentPacketMIs, but it is proving to be more difficu...

DFAPacketzer, Hexagon and bundles with 1 instruction
...uction, but I don't quite get it.
Here is the code that I have for a endPacket
// endPacket - End the current packet, bundle packet instructions and reset

void VLIWPacketizerList::endPacket(MachineBasicBlock *MBB,

if (CurrentPacketMIs.size() > 1) {
MachineInstr *MIFirst = CurrentPacketMIs.front();
finalizeBundle(*MBB, MIFirst, MI);
}
CurrentPacketMIs.clear();
ResourceTracker->clearResources();
}
Based on this, it looks like packets with one instruction are not finalized
(finalizeBundle is the one which inse...
