Indeed, flat assembler examples, the wise guidance is to avoid using the preprocessor as long as there's a way to achieve what you're trying to do with just language itself. The rept directive is used to compact repetitive assembly instructions into a block. FASM has a built-in eqtype operator, which takes two assembly expressions and produces a "true" value if both expressions yield the flat assembler examples type and "false" otherwise.

FASM flat assembler is an assembler for x86 processors. It supports Intel-style assembly language on the IA and x computer architectures. It claims high speed, size optimizations, operating system OS portability, and macro abilities. It is free and open-source software. The project was started in by Tomasz Grysztar, a. Privalov , at that time an undergraduate student of mathematics from Poland. It was released publicly in March

This section provides browsable versions of the manuals and other documentation included in the flat assembler packages, as well as few other relevant texts.

I use Pelles C to create the resources file. They require a name and can have an optional list of arguments, separated by commas. On x86 there might be different possible sequences of bytes corresponding to the same human-readable assembly instruction. Syntax highlighter language definition for Flat Assembler. Thread Starter. This multipass resolving applies not only to addresses of labels, but to the values of assembly-time variables as well in fact, I'm pretty sure FASM treats labels and assembly-time variables the same way. NeHe Tutorial in masm Assembly language Comparison of assemblers Disassembler Instruction set Low-level programming language Machine code Microassembler x86 assembly language. INF NaN data directives extension. We can use it in assembly-time conditions, of course. Updated Jan 28, Assembly. In the case above, a corresponds to the very first argument while b and c correspond to every odd and even arguments following that, in other words: the portion in the square brackets is repeatedly "matched" with the rest of the argument list. The situation is quite different in assembly land. Actually, FASM provides a handy library of macros that do exactly that, but I promised to be going as "from scratch" as possible, so no libraries for us :. Note that rcx eqtype rax yields true since both expressions have the same type.
