| * Code: Generic 32-bit binary operation. Provides an "instr" line to | |
| * specify an instruction that performs "%ecx = %ecx op %edx" | |
| * | |
| * For: add-int, and-int, mul-int, or-int, sub-int, xor-int | |
| * | |
| * Description: Perform a binary operation on two source registers | |
| * and store the result in a destination register. | |
| * | |
| * Format: AA|op CC|BB (23x) | |
| * | |
| * Syntax: op vAA, vBB, vCC | |
