Show whether we should use pre-decrement, pre-increment, post-decrement, or post-increment, for a PUSH instruction if a. Stack growth is ascending (from lower to higher address) with a full-stack stack pointer (SP points to the last item pushed) b. Stack growth is descending (from higher to lower address) with a full-stack stack pointer (SP points to the last item pushed) c. Stack growth is ascending (from lower to higher address) with an empty-stack stack pointer (SP points to the next available space) d. Stack growth is descending (from higher to lower address) with an empty-stack stack pointer (SP points to the next available space)

Sol165:

a. Pre-decrement should be used for a PUSH instruction when stack growth is ascending with a full-stack stack pointer, as it decrements the stack pointer before pushing the value onto the stack, ensuring that the value is stored at the correct memory address.

b. Pre-increment should be used for a PUSH instruction when stack growth is descending with a full-stack stack pointer, as it increments the stack pointer before pushing the value onto the stack, ensuring that the value is stored at the correct memory address.

c. Post-decrement should be used for a PUSH instruction when stack growth is ascending with an empty-stack stack pointer, as it first pushes the value onto the stack and then decrements the stack pointer, ensuring that the stack pointer points to the next available space.

d. Post-increment should be used for a PUSH instruction when stack growth is descending with an empty-stack stack pointer, as it first pushes the value onto the stack and then increments the stack pointer, ensuring that the stack pointer points to the next available space.
