| 4 | libclc is an open source, BSD licensed implementation of the library |
| 5 | requirements of the OpenCL C programming language, as specified by the |
| 6 | OpenCL 1.1 Specification. The following sections of the specification |
| 7 | impose library requirements: |
| 8 | |
| 9 | * 6.1: Supported Data Types |
| 10 | * 6.2.3: Explicit Conversions |
| 11 | * 6.2.4.2: Reinterpreting Types Using as_type() and as_typen() |
| 12 | * 6.9: Preprocessor Directives and Macros |
| 13 | * 6.11: Built-in Functions |
| 14 | * 9.3: Double Precision Floating-Point |
| 15 | * 9.4: 64-bit Atomics |
| 16 | * 9.5: Writing to 3D image memory objects |
| 17 | * 9.6: Half Precision Floating-Point |
| 18 | |
| 19 | libclc is intended to be used with the Clang compiler's OpenCL frontend. |
| 20 | |
| 21 | libclc is designed to be portable and extensible. To this end, it provides |
| 22 | generic implementations of most library requirements, allowing the target |
| 23 | to override the generic implementation at the granularity of individual |
| 24 | functions. |
| 25 | |
| 26 | libclc currently only supports the PTX target, but support for more |
| 27 | targets is welcome. |
