Shuxin Yang 7b0c94e207 Implement XOR reassociation. It is based on following rules: ... rule 1: (x | c1) ^ c2 => (x & ~c1) ^ (c1^c2), only useful when c1=c2 rule 2: (x & c1) ^ (x & c2) = (x & (c1^c2)) rule 3: (x | c1) ^ (x | c2) = (x & c3) ^ c3 where c3 = c1 ^ c2 rule 4: (x | c1) ^ (x & c2) => (x & c3) ^ c1, where c3 = ~c1 ^ c2 It reduces an application's size (in terms of # of instructions) by 8.9%.
