    * Code: Generic 32-bit "/2addr" binary operation.  Provides an
    *       "instr" line to specify an instruction that performs
    *       "%ecx = %ecx op %edx".
    *
    * For: add-int/2addr, and-int/2addr, mul-int/2addr, or-int/2addr,
    *      sub-int/2addr, xor-int/2addr
    *
    * Description: Perform a binary operation on two sources registers
    *              and store the result in the first source register
    *
    * Format: B|A|op (12x)
    *
    * Syntax: op vA, vB
