disassemble

disassemble Function

Summary

Prints the machine code of a compiled function.

Package

common-lisp

Signature

disassemble name-or-function => nil

Arguments

name-or-function⇩

Either a function object, a lambda expression or a symbol with a function definition.

Description

The function disassemble prints the machine code of a compiled function, to *standard-output*.

If the function denoted by name-or-function is not compiled then it is first compiled using the function compile. This happens if name-or-function is a lambda expression or an symbol naming an interpreted function.

An error is signaled if name-or-function is not suitable.

Examples

(disassemble  #'(lambda (x) (progn x)))
(disassemble  'cons)
(disassemble  #'map)

Notes

The output from disassemble lacks useful information such as local and lexical variable names. The representation of integers or characters or Lisp objects in general is not easily readable without detailed knowledge of the internals of the Lisp system and the host machine instruction set.
