I was experimenting with some optimized assembly and it substituted #defines
in place of register names. Think, "#define length r2" and such making the
resulting assembly more readable. I had made some missteps with the
Makefile because the files didn't get picked up; only later did I see that
the pattern wasn't in the Makefile.
