This page contains some libraries, a very basic example code to make things run and some other resources that might be helpful. Get tho the tutorial page to learn more on the use and coding.
nop.asm: An ASM code with no real operation.
driver.c: The C driver to link the ASM code with.
cdecl.h: Defines macros to specify the standard C calling convention for ASM "functions" (gobal labels to be precise)
asm_io.inc: Defines Basic Input/Output functions for ASM (use in 32-bit mode only)
The same functions are defined in here as well. This must be compiled in 32-bit mode and linked with the program if the
asm_io.inc library was included.
asm_io.inc but for 64-bit codes.
asm_io.asm, but for 64-bit programs.
Assembling Script: source code of a shell script I have prepared for simple ASM tasks that I am using frequntly. It can convert Object files or a C-code into an ASM in NASM syntax and compile to an Object file using NASM.
Objconv: Object File Converter is a converter from Object files to ASM in various syntax for both x86 and x64.
x86_64 registers: A table of all x64 CPU registers and additional information on both x86 and x64 registers. Note: rxx are the x64 registers, while exx are the x86 register names. (src: Microsoft Docs)
Linux System Call Codes:
A table of Linux x86 system calls and how to use them. We will use
sys_write in the examples mainly. Caution: this page was written in the GAS syntax, such as register names are preceded by a '%' for instance. (src: Prof. Dr.-Ing. A. Beck, HTW Dresden)
Intel® 64 and IA-32 Architectures Optimization Reference Manual: Intel's Reference Manual for IA-32 and x64 Optimization. The PDF contains some information on how to optimize your assembly code and includes notes on the efficiecy of some instructions and showing alternatives.
Additional useful links:
If you want to assemble codes not only to learn ASM, but also to have simplicity in mind, consider using the NASMX libraries:
NOTE: easier code gives greater maintainability. Especially if you use a code part in multiple places, consider using libraries.
