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.
