There already exists cl_khr_fp64 extension. So OpenCL C 3.0 and higher should use the feature, earlier versions still use the extension. OpenCL C 3.0 API spec states that extension will be not described in the option string if corresponding optional functionality is not supported (see 4.2. Querying Devices). Due to that fact the usage of features for OpenCL C 3.0 must be as follows: ``` $ clang -Xclang -cl-ext=+cl_khr_fp64,+__opencl_c_fp64 ... $ clang -Xclang -cl-ext=-cl_khr_fp64,-__opencl_c_fp64 ... ``` e.g. the feature and the equivalent extension (if exists) must be set to the same values Reviewed By: Anastasia Differential Revision: https://reviews.llvm.org/D96524 |

//===----------------------------------------------------------------------===// // C Language Family Front-end //===----------------------------------------------------------------------===// Welcome to Clang. This is a compiler front-end for the C family of languages (C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM compiler infrastructure project. Unlike many other compiler frontends, Clang is useful for a number of things beyond just compiling code: we intend for Clang to be host to a number of different source-level tools. One example of this is the Clang Static Analyzer. If you're interested in more (including how to build Clang) it is best to read the relevant web sites. Here are some pointers: Information on Clang: http://clang.llvm.org/ Building and using Clang: http://clang.llvm.org/get_started.html Clang Static Analyzer: http://clang-analyzer.llvm.org/ Information on the LLVM project: http://llvm.org/ If you have questions or comments about Clang, a great place to discuss them is on the Clang development mailing list: http://lists.llvm.org/mailman/listinfo/cfe-dev If you find a bug in Clang, please file it in the LLVM bug tracker: http://llvm.org/bugs/
