12 The standard Yasm distribution includes a number of modules for
13 different parsers (assembler syntaxes).
14
15 The parser is selected on the yasm(1) command line by use of the -p
16 parser command line option.
17
19 NASM syntax, selected with -p nasm, is the most full-featured syntax
20 supported by Yasm. Yasm is nearly 100% compatible with NASM for 16-bit
21 and 32-bit x86 code. Yasm additionally supports 64-bit AMD64 code with
22 Yasm extensions to the NASM syntax; see yasm_arch(7) for details. NASM
23 syntax is the Yasm default.
24
26 The GNU Assembler (GAS) is the de-facto cross-platform assembler for
27 modern Unix systems, and is used as the backend for the GCC compiler.
28 Yasm´s support for GAS syntax is moderately good, although immature:
29 not all directives are supported, and only 32-bit x86 and AMD64
30 architectures are supported. Nearly all of the GAS preprocessor is also
31 supported. Yasm´s GAS syntax support is good enough to handle
32 essentially all x86 and AMD64 GCC compiler output. The GAS parser can
33 be selected with -p gas.
