8.1 Examining Machine Code
==========================

To enable machine-level support, select `Source => Display Machine
Code'.  With machine code enabled, an additional _machine code window_
shows up, displaying the machine code of the current function.(1)  By
moving the sash at the right of the separating line between source and
machine code, you can resize the source and machine code windows.

   The machine code window works very much like the source window.  You
can set, clear, and change breakpoints by selecting the address and
pressing a `Break' or `Clear' button; the usual popup menus are also
available.  Breakpoints and the current execution position are displayed
simultaneously in both source and machine code.

   The `Lookup' button can be used to look up the machine code for a
specific function--or the function for a specific address.  Just click
on the location in one window and press `Lookup' to see the
corresponding code in the other window.

   If source code is not available, only the machine code window is
updated.

   You can customize various aspects of the disassembling window.
