Working with the mach kernel + x86-64 architecture assembly
The main purpose of this project is to study the mach kernel and the Mach-O
Executable, alongside the System V Application Binary Interface (ABI).
There's alreay an example on how to perform a SYS_write + SYS_exit calls
for the mach kernel at src/write_syscall.asm.
The code is written using the Netwide Assembler (NASM) format.
$ nasm -f macho64 src/write_syscall.asm
$ ld -macosx_version_min 10.15.0 -lSystem -no_pie -o bin/hello_world src/write_syscall.o
