| * Code: Generic 32-bit comparison operation. Provides a "revcmp" |
| * variable to specify the reverse comparison to perform. |
| * |
| * For: if-eq, if-ge, if-gt, if-le, if-lt, if-ne |
| * |
| * Description: Branch to the given destination if the comparison |
| * test between the given registers values is true. |

| * Format: B|A|op CCCC (22t) |
| * |
| * Syntax: op vA, vB, +CCCC |
