libc-assembly

16 libc (C standard library) functions recoded in assembly (bzero, memcpy, memmove, memset, rindex, strcasecmp, strchr, strcmp, strcpy, strcspn, strlen, strncmp, strnlen, strpbrk, strrchr, strstr).

Requirements :

gcc

nasm

Usage :

1. git clone https://github.com/neoski/libc-assembly.git

2. cd libc-assembly && make

3. You can use the libasm.so

A script is provided (test.sh) which compile C files testing the functions in a hidden directory (.test_files) and make a diff between the standard output and the one generated when the lib is loaded.

To run it : ./test.sh

Note : The current Makefile is correctly setted for MAC OS X. For Linux, change CFLAGS = -f macho64 to CFLAGS = -f elf64.
