A flag is provided ``-cl-no-stdinc`` to + suppress the default declarations non-native to the compiler. + +- Clang now compiles using OpenCL C version 1.2 by default if no version is + specified explicitly from the command line. + +- Clang now supports ``.clcpp`` file extension for sources written in + C++ for OpenCL. + +- Clang now accepts ``-cl-std=clc++1.0`` that sets C++ for OpenCL to + the version 1.0 explicitly. + +Misc common changes: + +- Added ``NULL`` definition in internal headers for standards prior to the + version 2.0. + +- Simplified use of pragma in extensions for ``double``, images, atomics, + subgroups, Arm dot product extension. There are less cases where extension + pragma is now required by clang to compile kernel sources. + +- Added missing ``as_size``/``as_ptr diff ``/``as_intptr``/``as_uintptr_t`` + operators to internal headers. + +- Added new builtin function for ndrange, ``cl_khr_subgroup_extended_types``, + ``cl_khr_subgroup_non_uniform_vote``, ``cl_khr_subgroup_ballot``, + ``cl_khr_subgroup_non_uniform_arithmetic``, ``cl_khr_subgroup_shuffle``, + ``cl_khr_subgroup_shuffle_relative``, ``cl_khr_subgroup_clustered_reduce`` + into the default Tablegen-based header. + +- Added online documentation for Tablegen-based header, OpenCL 3.0 support, + new clang extensions. + +- Fixed OpenCL C language version and SPIR address space reporting in DWARF. + +New extensions: + +- ``cl_khr_integer_dot_product`` for dedicated support of dot product. + +- ``cl_khr_extended_bit_ops`` for dedicated support of extra binary operations. + +- ``__cl_clang_bitfields`` for use of bit-fields in the kernel code. + +- ``__cl_clang_non_portable_kernel_param_types`` for relaxing some restrictions + to types of kernel parameters. + +OpenCL C 3.0 related changes: + +- Added parsing support for the optionality of generic address space, images + (including 3d writes and ``read_write`` access qualifier), pipes, program + scope variables, double-precision floating-point support. + +- Added optionality support for builtin functions (in ``opencl-c.h`` header) + for generic address space, C11 atomics. + +- Added ``memory_scope_all_devices`` enum for the atomics in internal headers. + +- Enabled use of ``.rgba`` vector components. + +C++ for OpenCL related changes: + +- Added ``__remove_address_space`` metaprogramming utility in internal headers + to allow removing address spaces from types. + +- Improved overloads resolution logic for constructors wrt address spaces. + +- Improved diagnostics of OpenCL specific types and address space qualified + types in ``reinterpret_cast`` and template functions. + +- Fixed ``NULL`` macro in internal headers to be compatible with C++. + +- Fixed use of ``half`` type.
