> What exactly are you expecting to be coalesced in this case, if I may ask?
I am expecting all of D.1129 and D.1131 to be coalesced so this:
D.1129 = r[0] + r[2];
r[0] = D.1129;
D.1131 = D.1129 + r[1];
r[1] = D.1131;
r[2] = D.1131 + r[2];
...is turned into what it was (like in second example):
r[0] = r[0] + r[2];
r[1] = r[0] + r[1];
r[2] = r[1] + r[2];
