10*a9fa9459Szrj@section Options
11*a9fa9459SzrjThe 32x32 version of @code{@value{AS}} accepts a @samp{-m32032} option to
12*a9fa9459Szrjspecify thiat it is compiling for a 32032 processor, or a
13*a9fa9459Szrj@samp{-m32532} to specify that it is compiling for a 32532 option.
14*a9fa9459SzrjThe default (if neither is specified) is chosen when the assembler
15*a9fa9459Szrjis compiled.
16*a9fa9459Szrj
17*a9fa9459Szrj@section Syntax
18*a9fa9459SzrjI don't know anything about the 32x32 syntax assembled by
19*a9fa9459Szrj@code{@value{AS}}.  Someone who understands the processor (I've never seen
20*a9fa9459Szrjone) and the possible syntaxes should write this section.
21*a9fa9459Szrj
22*a9fa9459Szrj@section Floating Point
23*a9fa9459SzrjThe 32x32 uses @sc{ieee} floating point numbers, but @code{@value{AS}}
24*a9fa9459Szrjonly creates single or double precision values.  I don't know if the
25*a9fa9459Szrj32x32 understands extended precision numbers.
26*a9fa9459Szrj
27*a9fa9459Szrj@section 32x32 Machine Directives
28*a9fa9459SzrjThe 32x32 has no machine dependent directives.

59*a9fa9459Szrj@cindex NS32K line comment character
60*a9fa9459SzrjThe presence of a @samp{#} appearing anywhere on a line indicates the
61*a9fa9459Szrjstart of a comment that extends to the end of that line.
62*a9fa9459Szrj
63*a9fa9459SzrjIf a @samp{#} appears as the first character of a line then the whole
64*a9fa9459Szrjline is treated as a comment, but in this case the line can also be a
65*a9fa9459Szrjlogical line number directive (@pxref{Comments}) or a preprocessor
66*a9fa9459Szrjcontrol command (@pxref{Preprocessing}).
67*a9fa9459Szrj
68*a9fa9459SzrjIf Sequent compatibility has been configured into the assembler then
69*a9fa9459Szrjthe @samp{|} character appearing as the first character on a line will
70*a9fa9459Szrjalso indicate the start of a line comment.

75*a9fa9459SzrjThe @samp{;} character can be used to separate statements on the same
76*a9fa9459Szrjline.
