I will look into this, but one of my questions would be is if the machine code differs between in ax, dx
and in ax
. If there is no difference, then I think the solution you have proposed is optimal, however, if they are different they probably both still need to be fuzzed, even if we don't set dx
to a specific random value before hand. What do you think @klaus-vb ?
The "in ax,dx" instruction has just one input operand. Pre-populating the value of ax is meaningless, because it will be overwritten by the instruction. Should speed up fuzzing quite a lot.
