LEAVE

The LEAVE instruction restores the stack frame by setting the stack pointer (RSP) to the value contained in the frame pointer (RBP) and then popping the value at the top of the stack into RBP.

The following table covers what the source and destinations can be.

DO NOT support LOCK

This instruction is available in 64-bit mode, compatibility mode, and 32-bit protected mode. In 64-bit mode, the operation utilizes r64 registers.

To avoid stack corruption or segmentation faults, the RBP register MUST be correctly initialized via a preceding ENTER instruction or a PUSH RBP / MOV RBP, RSP sequence. If RBP does not point to a valid saved frame pointer on the stack, the POP RBP phase of the instruction will load an arbitrary value into the frame pointer and leave the stack pointer in an inconsistent state.
