9 Machine Dependent Features
****************************
The machine instruction sets are (almost by definition) different on
each machine where 'as' runs. Floating point representations vary as
well, and 'as' often supports a few additional directives or
command-line options for compatibility with other assemblers on a
particular platform. Finally, some versions of 'as' 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.
