| <h1>libclc</h1> |
| <p> |
| libclc is an open source, BSD/MIT dual licensed |
| implementation of the library requirements of the |
| OpenCL C programming language, as specified by the <a |
| href="https://www.khronos.org/registry/OpenCL/specs/opencl-1.1.pdf">OpenCL |
| 1.1 Specification</a>. The following sections of the specification |
| impose library requirements: |
| <ul> |
| <li>6.1: Supported Data Types |
| <li>6.2.3: Explicit Conversions |
| <li>6.2.4.2: Reinterpreting Types Using as_type() and as_typen() |
| <li>6.9: Preprocessor Directives and Macros |
| <li>6.11: Built-in Functions |
| <li>9.3: Double Precision Floating-Point |
| <li>9.4: 64-bit Atomics |
| <li>9.5: Writing to 3D image memory objects |
| <li>9.6: Half Precision Floating-Point |
| </ul> |
| </p> |
| |
| <p> |
| libclc is intended to be used with the <a href="https://clang.llvm.org/">Clang</a> |
| compiler's OpenCL frontend. |
| </p> |
| |
| <p> |
| libclc is designed to be portable and extensible. To this end, |
| it provides generic implementations of most library requirements, |
| allowing the target to override the generic implementation at the |
| granularity of individual functions. |
| </p> |
| |
| <p> |
| libclc currently supports the AMDGCN, and R600 and NVPTX targets, but |
| support for more targets is welcome. |
