1 1 9 Machine Dependent Features 1 **************************** 1 1 The machine instruction sets are (almost by definition) different on 1 each machine where 'as' runs. Floating point representations vary as 1 well, and 'as' often supports a few additional directives or 1 command-line options for compatibility with other assemblers on a 1 particular platform. Finally, some versions of 'as' support special 1 pseudo-instructions for branch optimization. 1 1 This chapter discusses most of these differences, though it does not 1 include details on any machine's instruction set. For details on that 1 subject, see the hardware manufacturer's manual. 1
