; ---------------------------------
; SysCall Macro
; ---------------------------------

; To work around a Nasm warning this macro is defined
; as taking 0-7 args since the opcode syscall is used
; on 64-bit linux.
; Also, use caution when checking integral values that
; can benefit from sign-extension.  For example,
; 0xFFFFFFFF can be interpreted as -1 or 4294967295.
; The adventurous among you can also add checks for
; specific cpu types and inject opcodes based on speed
; vs. size considerations.
