## Description

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:

- types

- functions

- variables

- blocks

- control-flow statements

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.)
