| <refsect1 id="description"><title>Description</title> |
| <para> |
| This section describes the syntax with which <code>__attribute__</code> may be used, and the constructs to which attribute specifiers bind. |
| </para> |
| <para> |
| An attribute specifier is of the form <constant>__attribute__ ((<replaceable>attribute-list</replaceable>))</constant>. |
| </para> |
| <para> |
| This syntax is taken directly from GCC but unlike GCC, which allows attributes to be applied only to functions, types, and variables, OpenCL attributes can be associated with: |

| In general, the rules for how an attribute binds for a given context are non-trivial and the reader is pointed to GCC's documentation and Maurer and Wong's paper (See the "References" section in the <olink uri="references">OpenCL specification</olink> for details.) |
