In a logical shift instruction (also referred to as unsigned shift ), the bits that slide off the end disappear (except for the last, which goes into the carry flag), and the spaces are always filled with zeros. Logical shifts are best used with unsigned numbers. shr cnt, dest. GAS Syntax. shr dest, cnt. Intel Syntax.
