__ATTRIBUTE__(3clc) OpenCL Manual __ATTRIBUTE__(3clc)

NAME

__attribute__

__attribute__ ((attribute-list)) attribute-list: attribute<sub>opt</sub> attribute-list, attribute<sub>opt</sub> attribute: attribute-token attribute-argument-clause<sub>opt</sub> attribute-token: identifier attribute-argument-clause: ( attribute-argument-list ) attribute-argument-list: attribute-argument attribute-argument-list, attribute-argument attribute-argument: assignment-expression

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:

attributes-types(3clc)

functionQualifiers(3clc)

attributes-variables(3clc)

attributes-blocksAndControlFlow(3clc)

attributes-blocksAndControlFlow(3clc)

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[1] for details.)
