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. There is also no support for the GAS
31 preprocessor. Despite these limitations, Yasm's GAS syntax support is
32 good enough to handle essentially all x86 and AMD64 GCC compiler
33 output. The GAS parser can be selected with -p gas.
