+ *  %0 is the output parameter in EAX ("=a")
+ *  %1 and %2 are the input parameters in ECX ("c")
+ *  and an immediate value ("i") respectively
+ *  All actual register references are preceded with "%%" as in "%%edx"
+ *  Immediate values in the assembly are preceded by "$" as in "$0x1"
+ *  The final asm parameter are the operation altered non-output registers.
