Commit ID 009a0f88e05fde5ee16d7bac429d4c62ebe6bf53
Author Marco Costalba
Date 2012-12-31 10:34:18 UTC
Micro-optimization in evaluate_space() Since &-ing with SpaceMask restricts the set to the home half of the board, it is possible to use just one popcount instead of 2 by shifting "safe" to the other half of the board. This gives a small speedup especially on systems where hardware popcount is not available. Patch kindly sent by Richard Vida. No functional change.
