* A brief explanation as GNU inline assembly is a bit hairy
* %0 is the output parameter in EAX ("=a")
* %1 and %2 are the input parameters in ECX ("c")

* 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.
