LIBASM

Development environment

1. Homebrew installation

/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

2. nasm installation

brew install nasm 

Getting started

# For library
make

# For test
make test

Tester

• libasm_test

  git clone https://github.com/cacharle/libasm_test.git

• Libasm_Unit_Tests

  git clone https://github.com/valentinllpz/Libasm_Unit_Tests.git

Rules

• You must write 64 bits ASM. Beware of the "calling convention".

• You can’t do inline ASM, you must do ’.s’ files.

• You must compile your assembly code with nasm.

• You must use the Intel syntax, not the AT&T.

• The library must be called libasm.a.

• You must submit a main that will test your functions and that will compile with your library to show that it’s functional.

• You must rewrite the following functions in asm:

  • ft_strlen (man 3 strlen)
  • ft_strcpy (man 3 strcpy)
  • ft_strcmp (man 3 strcmp)
  • ft_write (man 2 write)
  • ft_read (man 2 read)
  • ft_strdup (man 3 strdup, you can call to malloc)

• You must check for errors during syscalls and properly set them when needed

• Your code must set the variable errno properly.

• For that, you are allowed to call the extern ___error.
