| This built-in functions must be encountered by all work-items in a |
| sub-group executing the kernel with the same argument values; otherwise the behavior is |
| undefined. We use the generic type name gentype to indicate the built-in OpenCL C scalar or |
| vector integer or floating-point data types or any user defined type built from these scalar and |
| vector data types can be used as the type for the arguments to the pipe functions listed in table |
| 6.29. |
| </p> |
| <p> |
| The half scalar and vector types can only be used if the |
| <a class="citerefentry" href="cl_khr_fp16.html"><span class="citerefentry"><span class="refentrytitle">cl_khr_fp16</span></span></a> |
| extension is supported. The double scalar |
| and vector types can only be used if double precision is supported. |
| </p> |
| <p> |
| Reservations made by a sub-group are ordered in |
| the pipe as they are ordered in the |
| program. Reservations made by different |
| sub-groups that belong to the same work-group can be |
| ordered using sub-group synchronization. The |
| order of sub-group based reservations that belong |
| to different work-groups is implementation defined. |
