| 13 | // Macro OPENCLEXTNAME or OPENCL_GENERIC_EXTENSION can be defined to enumerate all |
||
| 14 | // OpenCL extensions listed in this file. |
||
| 15 | // |
||
| 16 | // If extensions are to be enumerated with information about whether |
||
| 17 | // an extension is core or optional core and minimum OpenCL version |
||
| 18 | // when an extension becomes available, |
||
| 19 | // define OPENCL_GENERIC_EXTENSION(ext, pragma, avail, core, opt) where |
||
| 20 | // ext - name of the extension or optional core feature. |
||
| 21 | // pragma - true if extension needs pragmas or false otherwise. |
||
| 22 | // NOTE: extension pragma without any documentation detailing |
||
| 23 | // its behavior explicitly is deprecated. Therefore the default |
||
| 24 | // value is false. |
||
| 25 | // avail - minimum OpenCL version supporting it. |
||
| 26 | // core - OpenCL versions mask when the extension becomes core feature. |
||
| 27 | // 0U indicates not a core feature. |
||
| 28 | // opt - OpenCL versions mask when the extension becomes optional core |
||
| 29 | // feature. 0U indicates not a optional core feature. |
||
| 30 | // |
||
| 31 | // If extensions are to be enumerated without any information, |
||
| 32 | // define OPENCLEXTNAME(ext) where ext is the name of the extension. |
||
| 33 | // |
||
| 34 | // Difference between optional core feature and core feature is that the |
||
| 35 | // later is unconditionally supported in specific OpenCL version. |
||
| 36 | // |
||
| 37 | // As per The OpenCL Extension Specification, Section 1.2, in this file, an |
||
| 38 | // extension is defined if and only it either: |
||
| 39 | // * affects the OpenCL language semantics or its syntax, |
||
| 40 | // * adds built-in functions to the language. |
||
| 41 | // |
||
| 42 | // For such an extension, a preprocessor #define that matches the extension |
||
| 43 | // name must be created and a #pragma is required if and only if the |
||
| 44 | // compilation flow is impacted, e.g. due to a difference of syntax or |
||
| 45 | // semantics in the language compared to the core standard. #pragma directive |
||
| 46 | // has no effect for optional core and core features. |
