rax temporary register; with variable arguments passes information
about the number of SSE registers used; 1st return register
 
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
 
r11 temporary register
 
r12-15* callee-saved registers
 
xmm0­1 used to pass and return floating point arguments
 
xmm2­7 used to pass floating point arguments
