Author: Stéphane Nicolet Date: Thu Sep 22 08:31:23 2016 +0200 Timestamp: 1474525883 Simplify pinners conditions in SEE() Use the following transformations: - to check that A is included in B, testing "(A & ~B) == 0" is faster than "(A & B) == A" - to remove the intersection of A and B from A, doing "A &= ~B;" is as fast as "if (A & B) A &= ~B;" but is simpler. Overall, the simpler patch version is 0.3% than current master. No functional change.
