|
@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.
