This section describes the syntax with which __attribute__ may be used, and the constructs to which attribute specifiers bind.

An attribute specifier is of the form __attribute__ ((attribute-list)).

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 OpenCL specification for details.)
