* Code: Generic 32-bit "/2addr" binary operation. Provides an
* "instr" line to specify an instruction that performs
* "%xmm0 = %xmm0 op %xmm1".
*
* For: add-float/2addr, mul-float/2addr, sub-float/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
