History

Andrea Di Biagio 6077ca9abb [DAGCombiner] teach how to simplify xor/and/or nodes according to the following rules:

1)  (AND (shuf (A, C, Mask), shuf (B, C, Mask)) -> shuf (AND (A, B), C, Mask)
 2)  (OR  (shuf (A, C, Mask), shuf (B, C, Mask)) -> shuf (OR  (A, B), C, Mask)
 3)  (XOR (shuf (A, C, Mask), shuf (B, C, Mask)) -> shuf (XOR (A, B), V_0, Mask)

 4)  (AND (shuf (C, A, Mask), shuf (C, B, Mask)) -> shuf (C, AND (A, B), Mask)
 5)  (OR  (shuf (C, A, Mask), shuf (C, B, Mask)) -> shuf (C, OR  (A, B), Mask)
 6)  (XOR (shuf (C, A, Mask), shuf (C, B, Mask)) -> shuf (V_0, XOR (A, B), Mask)
