rbx* callee-saved register; optionally used as base pointer
rcx used to pass 4th integer argument to functions
rdx used to pass 3rd argument to functions 2nd return register
rsp* stack pointer
rbp* callee-saved register; optionally used as frame pointer
rsi used to pass 2nd argument to functions
rdi used to pass 1st argument to functions
r8 used to pass 5th argument to functions
r9 used to pass 6th argument to functions
r10 temporary register, used for passing a function's static chain pointer
