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.
