This will be removed + by LLVM passes if it can be proved that the function does not use convergent + operations. + +- Create a kernel wrapper for enqueued blocks, which simplifies enqueue support by + providing common functionality. + +- Added private address space explicitly in AST and refactored address space support + with several simplifications and bug fixes (`PR33419 <https://llvm.org/pr33419>`_ + and `PR33420 <https://llvm.org/pr33420>`_). + +- OpenCL now allows functions with empty parameters to be treated as if they had a + void parameter list (inspired from C++ support). OpenCL C spec update to follow. + +- General miscellaneous refactoring and cleanup of blocks support for OpenCL to + remove unused parts inherited from Objective C implementation. + +- Miscellaneous improvements in vector diagnostics. + +- Added half float load and store builtins without enabling half as a legal type + (``__builtin_store_half for double``, ``__builtin_store_halff`` for double, + ``__builtin_load_half for double``, ``__builtin_load_halff`` for float). + OpenMP Support in Clang ---------------------------------- |
