Jingyue Wu d4ceea3837 [SLSR] handle candidate form (B + i * S) ... Summary: With this patch, SLSR may rewrite S1: X = B + i * S S2: Y = B + i' * S to S2: Y = X + (i' - i) * S A secondary improvement: if (i' - i) is a power of 2, emit Y as X + (S << log(i' - i)). (S << log(i' -i)) is in a canonical form and thus more likely GVN'ed than (i' - i) * S.
