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

@subsection Special Characters
@cindex line comment character, NS32K
@cindex NS32K line comment character
The presence of a @samp{#} appearing anywhere on a line indicates the
start of a comment that extends to the end of that line.
If a @samp{#} appears as the first character of a line then the whole
line is treated as a comment, but in this case the line can also be a
logical line number directive (@pxref{Comments}) or a preprocessor
control command (@pxref{Preprocessing}).
If Sequent compatibility has been configured into the assembler then
the @samp{|} character appearing as the first character on a line will
also indicate the start of a line comment.
@cindex line separator, NS32K
@cindex statement separator, NS32K
@cindex NS32K line separator
The @samp{;} character can be used to separate statements on the same
line.
