//
// This file defines the list of supported OpenCL extensions.
//
//===----------------------------------------------------------------------===//
// Macro OPENCLEXTNAME or OPENCL_GENERIC_EXTENSION can be defined to enumerate all
// OpenCL extensions listed in this file.
//
// If extensions are to be enumerated with information about whether
// an extension is core or optional core and minimum OpenCL version
// when an extension becomes available,
// define OPENCL_GENERIC_EXTENSION(ext, pragma, avail, core, opt) where
// ext - name of the extension or optional core feature.
// pragma - true if extension needs pragmas or false otherwise.
// NOTE: extension pragma without any documentation detailing
// its behavior explicitly is deprecated. Therefore the default
// value is false.
// avail - minimum OpenCL version supporting it.
// core - OpenCL versions mask when the extension becomes core feature.
// 0U indicates not a core feature.
// opt - OpenCL versions mask when the extension becomes optional core
// feature. 0U indicates not a optional core feature.
//
// If extensions are to be enumerated without any information,
// define OPENCLEXTNAME(ext) where ext is the name of the extension.
//
// Difference between optional core feature and core feature is that the
// later is unconditionally supported in specific OpenCL version.
//
// 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. #pragma directive
// has no effect for optional core and core features.
