libasm

The aim of this project is to get familiar with assembly language.

Technical considerations

• The project is written in 64 bits ASM, compiled with NASM

• It follows the Intel syntax

• The following functions are rewritten in assembly:

  • ft_strlen: calculate the length of a string
  • ft_strcpy: copy a string
  • ft_strcmp: compare two strings
  • ft_write: write to a file descriptor
  • ft_read: read from a file descriptor
  • ft_strdup: duplicate a string

• Errors during syscalls need to be checked and Errno to be set properly

Create archive file and Test

This project is designed for Linux x86_64 and uses NASM

• Can be compiled and tested on Linux or macOS, though macOS only includes ft_strlen, ft_strcmp and ft_strcpy.

• To run on Apple Silicon, you must use Rosetta.

• Simply run 'make' to create the archive file (.a).

• Run 'make test' and depending on your OS, the correct main will be used.

• If using linux: ft_read, ft_write and ft_strdup will be included.

• There is an additional 'main_tester' provided by someone else including extra tests

• Run 'make test_main' to use this tester (only on Linux)
