Closed shaomeng closed 1 year ago

shaomeng commented 1 year ago

This PR introduces a custom bitmask, Bitmask, and uses it for storage of data structure m_LSP_mask. Experiments show that this bitmask improves the runtime significantly across all platforms tested.

This PR also moves refinement pass implementation to the base SPECK_INT class.
