| 27 | The PowerPC chip family includes several successive levels, using the same | |
| 28 | core instruction set, but including a few additional instructions at | |
| 29 | each level. There are exceptions to this however. For details on what | |
| 30 | instructions each variant supports, please see the chip's architecture | |
| 31 | reference manual. | |
