<para>The standard Yasm distribution includes a number of modules
|
|
for different parsers (assembler syntaxes).</para>

<title>NASM Parser</title>
|
|
|
|
<para>NASM syntax, selected with <option>-p nasm</option>, 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
|
|
|
|

|
<refentrytitle>yasm_arch</refentrytitle>
|
|
<manvolnum>7</manvolnum>
|
|
</citerefentry>
|
|
|
|
for details. NASM syntax is the Yasm default.</para>

<title>GAS Parser</title>
|
|
|
|
<para>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 <option>-p
|
|
gas</option>.</para>
