Subject: _aullshr question

Author: Jan K.

Hi, I experimented a bit with bitboard move generator(on 32-bit machine) and I
found that MSVC compiler inserts _aullshr function call everytime I try to shift
a bitboard. That seems expensive to me. Could someone please comment why this
happens and what really this function does(in ASM)?
