produces this clever code:

lwzu r3, lo16(_Time.1182)(r2)
lwz r2, 4(r2)
addic r4, r2, 1

instead of this:

la r3, lo16(_Time.1182)(r2)
lwz r2, lo16(_Time.1182)(r2)
lwz r3, 4(r3)
addic r4, r3, 1
addze r3, r2
blr
for:
long %millisecs() {
%tmp = load long* %Time.1182 ; <long> [#uses=1]
%tmp1 = add long %tmp, 1 ; <long> [#uses=1]
ret long %tmp1
}
