// This file defines the list of supported OpenCL extensions.
//
//===----------------------------------------------------------------------===//

// Macro OPENCLEXT or OPENCLEXT_INTERNAL can be defined to enumerate the
// OpenCL extensions listed in this file.
//
// If the extensions are to be enumerated without the supported OpenCL version,
// define OPENCLEXT(ext) where ext is the name of the extension.
//
// If the extensions are to be enumerated with supported OpenCL version,
// define OPENCLEXT_INTERNAL(ext, avail, core) where
//   ext - name of the extension or optional core feature.
//   avail - minimum OpenCL version supporting it.
//   core - minimum OpenCL version when the extension becomes optional core
//          feature or core feature. ~0U indicates not a core feature or an
//          optional core feature.
//
// As per The OpenCL Extension Specification, Section 1.2, in this file, an
// extension is defined if and only it either:
//  * affects the OpenCL language semantics or its syntax,
//  * adds built-in functions to the language.
//
// For such an extension, a preprocessor #define that matches the extension
// name must be created and a #pragma is required if and only if the
// compilation flow is impacted, e.g. due to a difference of syntax or
// semantics in the language compared to the core standard.
