Don't know why you'd assume it's a register.  It could just as
 well be nowhere.  If a later reference in the same function adds
 it to something else, there might not need to be any hardware
 anywhere representing the value 1.

Once you turn on a C optimizer, the real existence of local values
 is not assured.
