Use Register Variables

Setting this drop-down list box to

Normal or Aggressive allows the compiler to allocate

local variables in registers, rather than on the stack, when possible. This usually makes the

resulting code smaller and faster and, therefore, the default is that this drop-down list box

is enabled. However, in some applications, this drop-down list box might produce larger

and slower code when a function contains a large number of local variables.

The effect of this drop-down list box on overall program size and speed can only be

assessed globally across the entire application, which the compiler cannot do automati-

cally. Usually the overall application size is smaller but there can be exceptions to that
