  8. @section Options
  9. The 32x32 version of @code{@value{AS}} accepts a @samp{-m32032} option to
  10. specify that it is compiling for a 32032 processor, or a
  11. @samp{-m32532} to specify that it is compiling for a 32532 option.
  12. The default (if neither is specified) is chosen when the assembler
  13. is compiled.
  14. @section Syntax
  15. I don't know anything about the 32x32 syntax assembled by
  16. @code{@value{AS}}. Someone who understands the processor (I've never seen
  17. one) and the possible syntaxes should write this section.
  18. @section Floating Point
  19. The 32x32 uses @sc{ieee} floating point numbers, but @code{@value{AS}}
  20. only creates single or double precision values. I don't know if the
  21. 32x32 understands extended precision numbers.
  22. @section 32x32 Machine Directives
  23. The 32x32 has no machine dependent directives.

  45. @cindex line comment character, NS32K
  46. @cindex NS32K line comment character
  47. The presence of a @samp{#} appearing anywhere on a line indicates the
  48. start of a comment that extends to the end of that line.
  49. If a @samp{#} appears as the first character of a line then the whole
  50. line is treated as a comment, but in this case the line can also be a
  51. logical line number directive (@pxref{Comments}) or a preprocessor
  52. control command (@pxref{Preprocessing}).
  53. If Sequent compatibility has been configured into the assembler then
  54. the @samp{|} character appearing as the first character on a line will
  55. also indicate the start of a line comment.
  56. @cindex line separator, NS32K
  57. @cindex statement separator, NS32K
  58. @cindex NS32K line separator
  59. The @samp{;} character can be used to separate statements on the same
  60. line.
