Macro will be "optimized" by Keil C ?

If one macro is defined for "assignment":
Ex. #define equal(a,b) {a=b; }

And write: equal(A,1); equal(A,2); equal(A,3);

where A is pointer to XDATA space(mapped to H/W)

Keil C will "optimize" them and final result is A=3 ? or Keil C won't do this and expand them one by one ?

Thanks in advance...
