If a bundle is supposed to have at least 2 instructions, what is the point of VLIWPacketzierList::isSoloInstruction(...)? Say we have an instruction that can't be bundled with anything, how would one form a packet from it? -- R -------------- next part -------------- An HTML attachment was scrubbed...

I'm trying to figure out how Hexagon (I'm using it as an example for my own VLIW) is handling bundles with 1 instruction, 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 // DFA state. void VLIWPacketizerList::endPacket(MachineBasicBlock *MBB,
