report #13)
These come from compiled code, or your optimized assembly?
What I would do is track down the source of the address for these loads in
the asm listing, and see if I can tell. That said, b/c you mentioned all
other system regs are 0, it means that PC and STATUS remained in their
reset state, which means that whatever loads you see, they probably were
not reached in the program flow. But, again, I mentioned this is a long
shot, so lets see if you can learn something from the disassembly.
