Hi everyone,
I have been trying to run with SMT enabled in SE mode, using x86. It seems
ZeroRegister gets mapped to index 16 for the first hardware thread, which is
also register t0 that is used by the microcode. For the following hardware
threads the ZeroRegister will get mapped to 54, 92,
t0 must always return 0, and writes to it must always be ignored (or
overwritten before the next instruction). You're corrupted program counter
might be because you're using physical registers which aren't actually
there, accessing beyond the end of an array and reading/writing something
random.
