Destroy Stack Frame

leave

LEAVE destroys a stack frame of the form created by the ENTER instruction (see ENTER). It is functionally equivalent to MOV ESP,EBP followed by POP EBP (or \c{MOV SP,BP} followed by POP BP in 16-bit mode).

Forms

Every form of leave the assembler accepts, from NASM's own instruction table. The second column is the processor that introduced the form; a badge marks a form that needs an extension, that is lockable, or that long mode dropped.
