I've been surveying all the ISAs to see how they're using initiateAcc and completeAcc, and it looks like there are two cases where completeAcc needs to be (and apparently is) called on stores or store like instructions. The first are the StoreConditional instructions which have to (at least in some cases) write whether the store succeeded somewhere. The second are the swap instructions which have to write the old value of memory to a register. I don't expect this to be a revelation for anyone and it's not the source of any problems, but I wanted to verify what I'm saying here is correct and see if anyone can think of any other places where completeAcc needs to be called.
I've verified, as best I can by inspection, that initiateAcc isn't doing any writing back of registers. That's good, because that wouldn't work anyway. Some templates in ARM make it look like it might, but that's just from copy/paste, I think, and tracing back to where the templates get filled in and with what, there shouldn't be any registers to write.
