Dear Sirs:
I saw the following line in the preExecute() function of the SimpleCPU
model:
//If more fetch data is needed, pass it in.
Addr fetchPC = (pcState.instAddr() & PCMask) + fetchOffset;
I'm a little confused, isn't pcState.instAddr() returns the address
where the instruction will be fetched? Why does it AND the PCMask?
