YASM_PARSERS(7) Yasm Supported Parsers YASM_PARSERS(7)

NAME

yasm_parsers - Yasm Supported Parsers (Assembler Syntaxes)

SYNOPSIS

yasm -p parser [-r preproc] ...

DESCRIPTION

The standard Yasm distribution includes a number of modules for
different parsers (assembler syntaxes).

The parser is selected on the yasm(1) command line by use of the -p
parser command line option.

NASM PARSER

NASM syntax, selected with -p nasm, 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 yasm_arch(7) for
details. NASM syntax is the Yasm default.

GAS PARSER

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 -p gas.
