Before MSVS2015, MSVS's headers disagree about int32_t and PRIx32 and so on.
Provide a wrapper header to fix this, so that -Wformat can still be used.
Fixes PR23412.

Ever since the target attributes change, we don't need to guard these
headers with `requires`. Actually it's a bit worse, because if we do
then they are included textually under the covers, causing declarations
to appear in submodules they aren't supposed to be in.
llvm-svn: 240720
This involved removing the conditional inclusion and replacing them
with target attributes matching the original conditional inclusion
and checks. The testcase update removes the macro checks for each
file and replaces them with usage of the __target__ attribute, e.g.:
int __attribute__((__target__(("sse3")))) foo(int a) {
_mm_mwait(0, 0);
return 4;
}
This usage does require the enclosing function have the requisite
__target__ attribute for inlining and code generation - also for
any macro intrinsic uses in the enclosing function. There's no change
for existing uses of the intrinsic headers.

in section 10.1, __arm_{w,r}sr{,p,64}.
This includes arm_acle.h definitions with builtins and codegen to support
these, the intrinsics are implemented by generating read/write_register calls
which get appropriately lowered in the backend based on the register string
provided. SemaChecking is also implemented to fault invalid parameters.

This patch adds support for the following new instructions in the
Power ISA 2.07:
vpksdss
vpksdus
vpkudus
vpkudum
vupkhsw
vupklsw
These instructions are available through the vec_packs, vec_packsu,
vec_unpackh, and vec_unpackl built-in interfaces. These are
lane-sensitive instructions, so the built-ins have different
implementations for big- and little-endian, and the instructions must
be marked as killing the vector swap optimization for now.
The first three instructions perform saturating pack operations. The
fourth performs a modulo pack operation, which means it can be
represented with a vector shuffle, and conversely the appropriate
vector shuffles may cause this instruction to be generated. The other
instructions are only generated via built-in support for now.
I noticed during patch preparation that the macro __VSX__ was not
previously predefined when the power8-vector or direct-move features
are requested. This is an error, and I've corrected that here as
well.
Appropriate tests have been added.
There is a companion patch to llvm for the rest of this support.

xmmintrin.h includes emmintrin.h and vice versa if SSE2 is enabled. We break
this cycle for a modules build, and instead make the xmmintrin.h module
re-export the immintrin.h module. Also included is a fix for an assert in the
serialization code if a module exports another module that was declared later
in the same module map.

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.

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.
llvm-svn: 233807
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".
llvm-svn: 233804
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.

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.
Corresponding LLVM patch to follow.
llvm-svn: 232109
This is very much like D8088 (checked in at r231792).
Now that we've replaced the vinsertf128 intrinsics,
do the same for their extract twins.

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.
This is the sibling patch for the LLVM half of this change:

Differential Revision: http://reviews.llvm.org/D8088
llvm-svn: 231792
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.

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.

Use long long for the epi64 argument, like the other intrinsics.

Summary:
The definition for _mm256_insert_epi64 was taking an int, which would get
