Alexey Bataev b83b4e40fe [DEBUGINFO] Disable unsupported debug info options for NVPTX target.
Summary:
Some targets support only default set of the debug options and do not
support additional debug options, like NVPTX target. Patch introduced
virtual function supportsDebugInfoOptions() that can be overloaded
by the toolchain, checks if the target supports some debug
options and emits warning when an unsupported debug option is
found.

Pavel Labath d8c6290ba4 Move VersionTuple from clang/Basic to llvm/Support
Summary:
This kind of functionality is useful to other project apart from clang.
LLDB works with version numbers a lot, but it does not have a convenient
abstraction for this. Moving this class to a lower level library allows
it to be freely used within LLDB.

Since this class is used in a lot of places in clang, and it used to be
in the clang namespace, it seemed appropriate to add it to the list of
adopted classes in LLVM.h to avoid prefixing all uses with "llvm::".

Also, I didn't find any tests specific for this class, so I wrote a
couple of quick ones for the more interesting bits of functionality.

Clang calls "nvlink" for linking multiple object files with OpenMP
target functions, so correct this information when printing errors.

Adrian Prantl 9fc8faf9e6 Remove \brief commands from doxygen comments.
This is similar to the LLVM change https://reviews.llvm.org/D46290.

We've been running doxygen with the autobrief option for a couple of
years now. This makes the \brief markers into our comments
redundant. Since they are a visual distraction and we don't want to
encourage more \brief markers in new code either, this patch removes
them all.

Jonas Hahnfeld 7c78cc5273 [OpenMP] Consistently use cubin extension for nvlink
This was previously done in some places, but for example not for
bundling so that single object compilation with -c failed. In
addition cubin was used for all file types during unbundling which
is incorrect for assembly files that are passed to ptxas.
Tighten up the tests so that we can't regress in that area.

Justin Lebar 648f4cad52 [CUDA] Mark CUDA as a no-errno platform.
Summary:
CUDA doesn't support errno at all, so this is the right thing -- or at
least, in the right direction.

But also, this unbreaks the CUDA test-suite math tests [0] after D39481.
__cuda_cmath.h forwards nexttoward() to __builtin_nexttoward, which,
after that patch, was lowering to a libcall that doesn't exist in NVPTX.

Justin Lebar 066494d8c1 [CUDA] Print an error if you try to compile with < sm_30 on CUDA 9.
Summary:
CUDA 9's minimum sm is sm_30.

Ideally we should also make sm_30 the default when compiling with CUDA
9, but that seems harder than it should be.

Alex Lorenz 7e9c478cda Revert r310291, r310300 and r310332 because of test failure on Darwin
The commit r310291 introduced the failure. r310332 was a test fix commit and
r310300 was a followup commit. I reverted these two to avoid merge conflicts
when reverting.

The 'openmp-offload.c' test is failing on Darwin because the following
run lines:
// RUN:   touch %t1.o
// RUN:   touch %t2.o
// RUN:   %clang -### -no-canonical-prefixes -fopenmp=libomp -fopenmp-targets=nvptx64-nvidia-cuda -save-temps -no-canonical-prefixes %t1.o %t2.o 2>&1 \
// RUN:   | FileCheck -check-prefix=CHK-TWOCUBIN %s

trigger the following assertion:

Driver.cpp:3418:
    assert(CachedResults.find(ActionTC) != CachedResults.end() &&
           "Result does not exist??");

Gheorghe-Teodor Bercea f0f29608d0 [OpenMP] Extend CLANG target options with device offloading kind.
Summary: Pass the type of the device offloading when building the tool chain for a particular target architecture. This is required when supporting multiple tool chains that target a single device type. In our particular use case, the OpenMP and CUDA tool chains will use the same ```addClangTargetOptions ``` method. This enables the reuse of common options and ensures control over options only supported by a particular tool chain.

David L. Jones f561abab56 [Driver] Consolidate tools and toolchains by target platform. (NFC)
Summary:
(This is a move-only refactoring patch. There are no functionality changes.)

This patch splits apart the Clang driver's tool and toolchain implementation
files. Each target platform toolchain is moved to its own file, along with the
closest-related tools. Each target platform toolchain has separate headers and
implementation files, so the hierarchy of classes is unchanged.

There are some remaining shared free functions, mostly from Tools.cpp. Several
of these move to their own architecture-specific files, similar to r296056. Some
of them are only used by a single target platform; since the tools and
toolchains are now together, some helpers now live in a platform-specific file.
The balance are helpers related to manipulating argument lists, so they are now
in a new file pair, CommonArgs.h and .cpp.

I've tried to cluster the code logically, which is fairly straightforward for
most of the target platforms and shared architectures. I think I've made
reasonable choices for these, as well as the various shared helpers; but of
course, I'm happy to hear feedback in the review.

There are some particular things I don't like about this patch, but haven't been
able to find a better overall solution. The first is the proliferation of files:
there are several files that are tiny because the toolchain is not very
different from its base (usually the Gnu tools/toolchain). I think this is
mostly a reflection of the true complexity, though, so it may not be "fixable"
in any reasonable sense. The second thing I don't like are the includes like
"../Something.h". I've avoided this largely by clustering into the current file
structure. However, a few of these includes remain, and in those cases it
doesn't make sense to me to sink an existing file any deeper.
