| * | |
| * Code: Generic 64-bit "/2addr" binary operation. Provides an | |
| * "instr" line to specify an instruction that performs | |
| * "%xmm0= %xmm0 op %xmm1". | |
| * | |
| * For: add-double/2addr, add-long/2addr, and-long/2addr, mul-long/2addr, | |
| * or-long/2addr, sub-double/2addr, sub-long/2addr, xor-long/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 | |
