Artem Belevich 4e192df778 [cuda] Added support for CUDA built-in variables.
Added cuda_builtin_vars.h which implements built-in CUDA variables
using __declattr(property).

Fields of built-in variables (except for warpSize) are implemented
using __declattr(property) which replaces read/write of a member field
with a call to a getter/setter member function, in this case with
appropriate NVPTX builtin.

Added a test case to check diagnostics on attempt to construct or
improperly access a built-in variable.

Ulrich Weigand cc67344a86 [SystemZ] Add header files to Makefile / module.modulemap
This should fix build-bot failures after r233804.

The patch also adds a "systemz" feature, and renames the
"transactional-execution" feature to "htm", since it turns
out "-" is not a legal character in module feature names.

Ulrich Weigand 3a610ebf1e [SystemZ] Support transactional execution on zEC12
The zEC12 provides the transactional-execution facility.  This is exposed
to users via a set of builtin routines on other compilers.  This patch
adds clang support to enable those builtins.  In partciular, the patch:

- enables the transactional-execution feature by default on zEC12
- allows to override presence of that feature via the -mhtm/-mno-htm options
- adds a predefined macro __HTM__ if the feature is enabled
- adds support for the transactional-execution GCC builtins
- adds Sema checking to verify the __builtin_tabort abort code
- adds the s390intrin.h header file (for GCC compatibility)
- adds s390 sections to the htmintrin.h and htmxlintrin.h header files

Since this is first use of target-specific intrinsics on the platform,
the patch creates the include/clang/Basic/BuiltinsSystemZ.def file and
hooks it up in TargetBuiltins.h and lib/Basic/Targets.cpp.

An associated LLVM patch adds the required LLVM IR intrinsics.

For reference, the transactional-execution instructions are documented
in the z/Architecture Principles of Operation for the zEC12:
http://publibfp.boulder.ibm.com/cgi-bin/bookmgr/download/DZ9ZR009.pdf
The associated builtins are documented in the GCC manual:
http://gcc.gnu.org/onlinedocs/gcc/S_002f390-System-z-Built-in-Functions.html
The htmxlintrin.h intrinsics provided for compatibility with the IBM XL
compiler are documented in the "z/OS XL C/C++ Programming Guide".

Kit Barton 8246f28237 Add Hardware Transactional Memory (HTM) Support
This patch adds Hardware Transaction Memory (HTM) support supported by ISA 2.07
(POWER8). The intrinsic support is based on GCC one [1], with both 'PowerPC HTM
Low Level Built-in Functions' and 'PowerPC HTM High Level Inline Functions'
implemented.

Along with builtins a new driver switch is added to enable/disable HTM
instruction support (-mhtm) and a header with common definitions (mostly to
parse the TFHAR register value). The HTM switch also sets a preprocessor builtin
HTM.

The HTM usage requires a recently newer kernel with PPC HTM enabled. Tested on
powerpc64 and powerpc64le.

This is send along a llvm patch to enabled the builtins and option switch.

Sanjay Patel 0a6da5de55 [X86, AVX2] Replace inserti128 and extracti128 intrinsics with generic shuffles
This is nearly identical to the v*f128_si256 parts of r231792 and r232052.

AVX2 introduced proper integer variants of the hacked integer insert/extract
C intrinsics that were created for this same functionality with AVX1.

This should complete the front end fixes for insert/extract128 intrinsics.

Sanjay Patel 7f6aa52e93 [X86, AVX] Replace vinsertf128 intrinsics with generic shuffles.
We want to replace as much custom x86 shuffling via intrinsics
as possible because pushing the code down the generic shuffle
optimization path allows for better codegen and less complexity
in LLVM.

Juergen Ributzka 9baa03fc07 Lower _mm256_broadcastsi128_si256 directly to a vector shuffle.
Originally we were using the same GCC builtins to lower this AVX2 vector
intrinsic. Instead we will now lower it directly to a vector shuffle.

This will not only allow LLVM to generate better code, but it will also allow us
to remove the GCC intrinsics.

Dmitri Gribenko a586ea13a4 Restore the libc++ definition of max_align_t on Apple platforms
Clang has introduced ::max_align_t in stddef.h in r201729, but libc++ was
already defining std::max_align_t on Darwin because there was none in the
global namespace.  After that Clang commit though, libc++ started defining
std::max_align_t to be a typedef for ::max_align_t, which has a different
definition.  This changed the ABI.  This commit restores the previous
definition.

Chandler Carruth 032d422d2e Effectively revert r151058 which caused Clang's unwind.h to defer to
libunwind in all cases when installed.

At the time, Clang's unwind.h didn't provide huge chunks of the
LSB-specified unwind interface, and was generally too aenemic to use for
real software. However, it has since then become a strict superset of
the APIs provided by libunwind on Linux. Notably, you cannot compile
llgo's libgo library against libunwind, but you can against Clang's
unwind.h. So let's just use our header. =] I've checked pretty
thoroughly for any incompatibilities, and I am not aware of any.

An open question is whether or not we should continue to munge
GNU_SOURCE here. I didn't touch that as it potentially has compatibility
implications on systems I cannot easily test -- Darwin. If a Darwin
maintainer can verify that this is in fact unnecessary and remove it,
cool. Until then, leaving it in makes this change a no-op there, and
only really relevant on Linux systems where it is pretty clearly the
right way to go.

This still lower to the same intrinsics as before.

This is preparation for bounds checking the immediate on the avx version of the builtin so we don't pass illegal immediates into the backend. Since SSE uses a smaller size immediate its not possible to bounds check when using a shared builtin. Rather than creating a clang specific builtin for the different immediate, I decided (after consulting with Chandler) that it was better to match gcc.
