Question

What is the purpose of the ENTER instruction?

a.

To restore ESP and EBP to their previously stored values

b.

To push EBP into the stack and set it to point to the top of the local variable area

c.

To create a new stack frame that will be used by the callee

d.

All of the above

Posted under Reverse Engineering

Answer: (b).To push EBP into the stack and set it to point to the top of the local variable area Explanation:The ENTER instruction sets up a stack frame by pushing EBP into the stack and setting it to point to the top of the local variable area, and it supports the management of nested stack frames within the same procedure.
