11@section Options
12The 32x32 version of @code{@value{AS}} accepts a @samp{-m32032} option to
13specify thiat it is compiling for a 32032 processor, or a
14@samp{-m32532} to specify that it is compiling for a 32532 option.
15The default (if neither is specified) is chosen when the assembler
16is compiled.
17
18@section Syntax
19I don't know anything about the 32x32 syntax assembled by
20@code{@value{AS}}. Someone who understands the processor (I've never seen
21one) and the possible syntaxes should write this section.
22
23@section Floating Point
24The 32x32 uses @sc{ieee} floating point numbers, but @code{@value{AS}}
25only creates single or double precision values. I don't know if the
2632x32 understands extended precision numbers.

28@section 32x32 Machine Directives
29The 32x32 has no machine dependent directives.

59@cindex line comment character, NS32K
60@cindex NS32K line comment character
61The presence of a @samp{#} appearing anywhere on a line indicates the
62start of a comment that extends to the end of that line.
63
64If a @samp{#} appears as the first character of a line then the whole
65line is treated as a comment, but in this case the line can also be a
66logical line number directive (@pxref{Comments}) or a preprocessor
67control command (@pxref{Preprocessing}).
68
69If Sequent compatibility has been configured into the assembler then
70the @samp{|} character appearing as the first character on a line will
71also indicate the start of a line comment.
72
73@cindex line separator, NS32K
74@cindex statement separator, NS32K
75@cindex NS32K line separator
76The @samp{;} character can be used to separate statements on the same
77line.
