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 .
