"You can not just pop the return address and push a new one. You need to Restore the the pointer."-->?
Not understood, sorry.Why I can not pop the return add.? "If there are any calls on the stack you will eventualy overflow the stack." But before the push operation to the stack there is pop operation to empty stack so there is no overflow possibility.I have observed the ram space on the simulation Thanks for your interest, Expecting answer |
