.SH "DESCRIPTION"
|

|
.PP
|
||
|
|
The standard Yasm distribution includes a number of modules for different parsers (assembler syntaxes)\&.
|
||
|
|
.PP
|
||
|
|
The parser is selected on the
|
||
|
|
\fByasm\fR(1)
|
||
|
|
command line by use of the
|
||
|
|
\fB\-p \fR\fB\fIparser\fR\fR
|
||
|
|
command line option\&.

||
|
|
.SH "NASM PARSER"
|
||
|
|
.PP
|
||
|
|
NASM syntax, selected with
|
||
|
|
\fB\-p nasm\fR, is the most full\-featured syntax supported by Yasm\&. Yasm is nearly 100% compatible with NASM for 16\-bit and 32\-bit x86 code\&. Yasm additionally supports 64\-bit AMD64 code with Yasm extensions to the NASM syntax; see
|
||
|
|
\fByasm_arch\fR(7)
|
||
|
|
for details\&. NASM syntax is the Yasm default\&.
|
||
|
|
.SH "GAS PARSER"
|
||
|
|
.PP
|
||
|
|
The GNU Assembler (GAS) is the de\-facto cross\-platform assembler for modern Unix systems, and is used as the backend for the GCC compiler\&. Yasm\'s support for GAS syntax is moderately good, although immature: not all directives are supported, and only 32\-bit x86 and AMD64 architectures are supported\&. Nearly all of the GAS preprocessor is also supported\&. Yasm\'s GAS syntax support is good enough to handle essentially all x86 and AMD64 GCC compiler output\&. The GAS parser can be selected with
|
||
|
|
\fB\-p gas\fR\&.
