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.

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.
