You don't. Since GCC 3.1, you can name variables in asm (the names exist 
in a different namespace from C variables so they have to be bound as 
constraints). The example from 
http://gcc.gnu.org/onlinedocs/gcc/Extended-Asm.html reads

asm ("fsinx %[angle],%[output]"
           : [output] "=f" (result)
           : [angle] "f" (angle));
