* IA32 calling convention and general notes:
*
* EAX, ECX, EDX - general purpose scratch registers (caller-saved);
*
* The stack (%esp) - used to pass arguments to functions
*
* EAX - holds the first 4 bytes of a return
* EDX - holds the second 4 bytes of a return
*
* EBX, ESI, EDI, EBP - are callee saved
*
* CS, DS, SS - are segment registers
* ES, FS, GS - are segment registers. We will try to avoid using these registers
*
* The stack is "full descending". Only the arguments that do not fit * in the first two arg registers are placed on the stack.
* "%esp" points to the first stacked argument (i.e. the 3rd arg).
