| 11 | ISA 3.0 of the PowerPC added new atomic memory operation (amo) | |
| 12 | instructions. GCC provides support for these instructions in 64-bit | |
| 13 | environments. All of the functions are declared in the include file | |
| 14 | ``amo.h``. | |
| 15 | ||
| 16 | The functions supported are: | |

| 18 | .. code-block:: c++ | |
