I apologise for the previous message, but I accidentally hit reply.
So as I was saying:
In my case lets say that in the fetch_impl.hh file I have added the
following code after the fetching of the original instruction.
//Instruction fetch
if (cpu->readMiscReg(AlphaISA::IPR_ICM, tid) !=
AlphaISA::mode_kernel) {
//Fault Injection
}
Also in case you have a DynInst Object (e.g O3DynInst *xc) available you can
use
if (xc->readMiscReg(AlphaISA::IPR_ICM) != AlphaISA::mode_kernel) {
//...
}
That's all I have got until now.
If anyone else has more on the topic, I would also be interested.
