     19     * Code: Generic 32-bit binary operation.  Provides an "instr" line to
     20     *       specify an instruction that performs "%edx = %edx op %cl"

     22     * For: shl-int, shr-int, ushr-int

     24     * Description: Perform a binary operation on two source registers
     25     *              and store the result in a destination register.

     27     * Format: AA|op CC|BB (23x)
