- <p>The machine instruction sets are (almost by definition) different on
- each machine where <code>as</code> runs. Floating point representations
- vary as well, and <code>as</code> often supports a few additional
- directives or command-line options for compatibility with other
- assemblers on a particular platform. Finally, some versions of
- <code>as</code> support special pseudo-instructions for branch
- optimization.
- </p>
- <p>This chapter discusses most of these differences, though it does not
- include details on any machine’s instruction set. For details on that
- subject, see the hardware manufacturer’s manual.
