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.
WebJul 29, 2024 · The SHR instruction is an abbreviation for ‘Shift Right’. This instruction simply shifts the mentioned bits in the register to the right side one by one by inserting the same number (bits that are being shifted) of zeroes from the left end. ...
