SHRD         Double Precision Shift Right (386)      Flags: O D I T S Z A P C
                                                            ?       * * ? * *
SHRD operand1, operand2, count

           Logic:        operand1|operand2 . SHR(operand1|operand2,count)

     SHRD is a double precision shift right instruction.

     This instruction takes three operands. Taken together, the first two
     operands (operand1 and operand2) form a 32-bit or 64-bit entity,
     OP. The third operand, 8 bits long, is the count. The SHRD
     instruction shifts OP right by count places.
