yasm_parsers − Yasm Supported Parsers (Assembler Syntaxes)
|
yasm −p parser [−r preproc] ... |
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 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.
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.
