Libasm is a project 42 written in ASM and C aiming to discover the assembler by coding a small library of some functions. Here is the list of functions:
- read
- strcmp
- strcpy
- strdup
- strlen
- write
In the test/ folder, a main.c is there to compare the result of the functions coded in assembler with the functions coming from the libC.
The goal of the project was to discover the subtleties of the assembler and to go a little deeper into the depth of C via the discovery of an even lower level language. To discover the usefulness and management of registers.
The code is written in 64 bits ASM, not inline ASM.
The syntax used is Intel and not AT&T.
The code is compiled with nasm.
If you want to check the behavior or these functions,
Run test/tester.sh
./tester.sh
then run:
./run_test
