librairie statique codé en ASM64 Work on MacOSX and linux distribution
Interger ou pointer arguments: RDI, RSI, RDX, RCX, R8, R9 (for syscall R10 is use instead of RCX. Other params are pushed on stack) Floating arguments: XMM0, XMM1, XMM2, XMM3, XMM4, XMM5, XMM6 and XMM7
Return values are stored in RAX and return value up to 128bits are stored in RAX ans RDX.
Callee-saved registers: RBX, RBP, R12-R15. others register must be saved by the caller to preserve their values.
calling convention: System V Application Binary Interface AMD64
On syscall error, rax is filled with the negative error code.
On syscall rdx is clobbered. On syscall error, CF (carry flag) is raised and rax is filled with error code.
Make: Compile the library Make test: Compile the library and the test executable.
