OpenCL C Language Changes in Clang

+Clang now has support for all OpenCL 2.0 features. In particular, the
following
+features have been completed since the previous release:
+
+- Pipe builtin functions (s6.13.16.2-4).
+- Address space conversion functions ``to_{global/local/private}``.
+- ``nosvm`` attribute support.
+- Improved diagnostic and generation of Clang Blocks used in OpenCL kernel
code.
+- ``opencl_unroll_hint`` pragma.
+
+Several miscellaneous improvements have been made:
+
+- Supported extensions are now part of the target representation to give
correct
+ diagnostics for unsupported target features during compilation. For example,
+ when compiling for a target that does not support the double precision
+ floating point extension, Clang will give an error when encountering the
+ ``cl_khr_fp64`` pragma. Several missing extensions were added covering up to
+ and including OpenCL 2.0.
+- Clang now comes with the OpenCL standard headers declaring builtin types and
+ functions up to and including OpenCL 2.0 in ``lib/Headers/opencl-c.h``. By
+ default, Clang will not include this header. It can be included either using
+ the regular ``-I`` directive or (if the default one
+ from installation is to be used) using the ``-finclude-default-header``
+ frontend flag.
+
+ Example:
+
+ .. code-block:: none
+
+echo "bool is_wg_uniform(int i){return
get_enqueued_local_size(i)==get_local_size(i);}" > test.cl
+clang -cc1 -finclude-default-header -cl-std=CL2.0 test.cl
+
+ All builtin function declarations from OpenCL 2.0 will be automatically
+ visible in test.cl.
+- Image types have been improved with better diagnostics for access qualifiers.
+ Images with one access qualifier type cannot be used in declarations for
+ another type. Also qualifiers are now propagated from the frontend down to
+ libraries and backends.
+- Diagnostic improvements for OpenCL types, address spaces and vectors.
+- Half type literal support has been added. For example, ``1.0h`` represents a
+ floating point literal in half precision, i.e., the value ``0xH3C00``.
+- The Clang driver now accepts OpenCL compiler options ``-cl-*`` (following the
+ OpenCL Spec v1.1-1.2 s5.8). For example, the ``-cl-std=CL1.2`` option from
the
+ spec enables compilation for OpenCL 1.2, or ``-cl-mad-enable`` will enable
+ fusing multiply-and-add operations.
+- Clang now uses function metadata instead of module metadata to propagate
+ information related to OpenCL kernels e.g. kernel argument information.
OpenMP Support in Clang

[llvm-branch-commits] [cfe-branch] r278605 - Merge r278393 and r278395.
Author: ed
Date: Sat Aug 13 15:43:56 2016
New Revision: 278605
URL: http://llvm.org/viewvc/llvm-project?rev=278605&view=rev
Log:
Merge r278393 and r278395.
LLVM/Clang 3.8 is directly usable as a cross compiler for CloudABI/i686.
In 3.9rc1 there are a couple of regressions in the driver that cause it
to be less usable:
- PIE was enabled unconditionally, even though it's only available for
x86-64 and aarch64.
- Some inline assembly fails to build, due to a shortage of registers,
as frame pointers are not omitted.
Both these changes are fairly low risk (read: they don't affect other
targets), so go ahead and merge them into 3.9, so we can use an
unmodified compiler on all architectures.
