	Are NOPS required if area is skipped all together? « on: September 07, 2014, 12:34:29 PM »

If I delete a function and jmp over it all together do I have to fill it with NOPS or can I just fill it with FF ?

Thanks,
Rey

If you jump over the whole function, it can be FF:ed, but you have to be sure the function isn't called from somewhere

As long as the instruction pointer never points to that code, it can be anything. If you are removing instructions from code that is executed - you need to use NOP.
