I'm unclear how does DFAPacketizer and the scheduler know a given instruction is a load. Here is what I'm talking about Let's assume my VLIW target is described as follows: def MyTargetItineraries : ProcessorItineraries<[Slot0, Slot1], [], [ .............................. InstrItinData<RI, [InstrStage<1, [Slot0, Slot1]>]>, InstrItinData<LD, [InstrStage<1, [Slot0, Slot1]>]>, // <-- This itinerary class describes load instructions InstrItinData<BR, [InstrStage&l...

I'm curious how does hexagon hardware decide which slot to use for a given instruction? Is there special hardware to make that decision? I'm asking because I didn't see any information about which slot to use for a given packet. Is it even possible to pass this kind of information through assembly? Say hardware sees a packet and the packet tells it which slot to use. I would greatly

As you can see mayLoad is never really set to 1 anywhere however it still seems to be using a LoadLatency of 2. What am I missing?

Hi. Thank you for comments on asm code paravirtualization. Its direction is getting clear. Although it hasn't been finished yet, I'd like to start discussion on ia64 intrinsics paravirtualization. This patch set is just for discussion so that it is a subset of xen Linux/ia64 domU paravirtualization, not self complete. You can get the full patched tree by typing git clone
