AllCallbacks is currently only used to call onStartOfTranslationUnit and
onEndOfTranslationUnit on them. In this (and any other scenario I can
come up with), it is important (or at least better) not to have
duplicates in this container. E.g. currently onEndOfTranslationUnit is
called repeatedly on the same callback for every matcher that is
registered with it.

ASTUnit was creating multiple FileManagers and throwing them away. Reuse
the one from Tooling. No functionality change now but necessary for

Adds `addTargetAndModeForProgramName`, a utility function that will add
appropriate `-target foo` and `--driver-mode=g++` tokens to a command
line for driver invocations of the form `a/b/foo-g++`. It is intended to
support tooling: for example, should a compilation database record some
invocation of `foo-g++` without these implicit flags, a Clang tool may
use this function to add them back.

Apart from being cleaner this also means that clang-format no longer has
access to the host file system. This isn't necessary because clang-format
never reads includes :)
Includes minor tweaks and bugfixes found in the VFS implementation while
running clang-format tests.

that change turns out to not be reasonable: mutating the AST of a parsed
template during instantiation is not a sound thing to do, does not work across
chained PCH / modules builds, and is in any case a special-case workaround to a
more general problem that should be solved centrally.

include/clang/CodeGenABITypes.h is in meant to be included by external

For RealFileSystem this is getcwd()/chdir(), the synthetic file systems can
make up one for themselves. OverlayFileSystem now synchronizes the working
directories when a new FS is added to the overlay or the overlay working
directory is set. This allows purely artificial file systems that have zero
ties to the underlying disks.

This is a simple file system tree of memory buffers that can be filled by a
client. In conjunction with an OverlayFS it can be used to make virtual
files accessible right next to physical files. This can be used as a
replacement for the virtual file handling in FileManager and which I intend
to remove eventually.

In versions of clang prior to r238238, __declspec was recognized as a keyword in
all modes. It was then changed to only be enabled when Microsoft or Borland
extensions were enabled (and for CUDA, as a temporary measure). There is a
desire to support __declspec in Playstation code, and possibly other
environments. This commit adds a command-line switch to allow explicit
enabling/disabling of the recognition of __declspec as a keyword. Recognition
is enabled by default in Microsoft, Borland, CUDA, and PS4 environments, and
disabled in all other environments.

Diagnose when a pointer to const T is used as the first argument in at atomic

All global variables that are not enclosed in a declare target region
must be captured in the target region as local variables do. Currently,
there is no support for declare target, so this patch adds support for

Usually, when using LTO with a clang installation newer than the
system's one, there's a libLTO.dylib version mismatch and LTO fails. One
solution to this is to make ld point to the right libLTO.dylib by
changing DYLD_LIBRARY_PATH.
However, ld64 supports specifying the complete path to the desired
libLTO.dylib through the -lto_library option. This commit adds support
for the clang driver to use this option whenever it's capable of finding
a libLTO.dylib in clang's installed library directory. This way, we
don't need to rely on DYLD_LIBRARY_PATH nor get caught by version
mismatches.

This commit supports Sean Eveson's work on loop widening. It is NFC for now.
It adds a new TK_EntireMemSpace invalidation trait that, when applied to a
MemSpaceRegion, indicates that the entire memory space should be invalidated.
Clients can add this trait before invalidating. For example:
RegionAndSymbolInvalidationTraits ITraits;
ITraits.setTrait(MRMgr.getStackLocalsRegion(STC),
RegionAndSymbolInvalidationTraits::TK_EntireMemSpace);
This commit updates the existing logic invalidating global memspace regions for
calls to additionally handle arbitrary memspaces. When generating initial
clusters during cluster analysis we now add a cluster to the worklist if
the memspace for its base is marked with TK_EntireMemSpace.
This also moves the logic for invalidating globals from ClusterAnalysis to
invalidateRegionsWorker so that it is not shared with removeDeadBindingsWorker.
There are no explicit tests with this patch -- but when applied to Sean's patch
for loop widening in http://reviews.llvm.org/D12358 and after updating his code
to set the trait, the failing tests in that patch now pass.

Summary:
This patch moves getCompilerRT() from the clang::driver::tools namespace to
the ToolChain class. This is needed for multilib toolchains that need to
place their libraries in Clang's resource directory with a layout that is
different from the default one.

This allows clang-format to align identifiers in consecutive
declarations. This is useful for increasing the readability of the code
in the same way the alignment of assignations is.
The code is a slightly modified version of the consecutive assignment
alignment code. Currently only the identifiers are aligned, and there is
no support of alignment of the pointer star or reference symbol.
The patch also solve the issue of alignments not being possible due to
the ColumnLimit for both the existing AlignConsecutiveAligments and the
new AlignConsecutiveDeclarations.

- Remove virtual SC_OpenCLWorkGroupLocal storage type specifier
as it conflicts with static local variables now and prevents
diagnosing static local address space variables correctly.
- Allow static local and global variables (OpenCL2.0 s6.8 and s6.5.1).
- Improve diagnostics of allowed ASes for variables in different scopes:
(i) Global or static local variables have to be in global
or constant ASes (OpenCL1.2 s6.5, OpenCL2.0 s6.5.1);
(ii) Non-kernel function variables can't be declared in local
or constant ASes (OpenCL1.1 s6.5.2 and s6.5.3).

FunctionParmPackExpr actually stores an array of ParmVarDecl* (and
accessors return that). But, the FunctionParmPackExpr::Create()
constructor accepted an array of Decl *s instead.
It was easy for this mismatch to occur without any obvious sign of
something wrong, since both the store and the access used independent
'reinterpet_cast<XX>(this+1)' calls.

specification) to an error. No compiler other than Clang seems to allow this,
and it doesn't seem like a useful thing to accept as an extension in general.
The current behavior was added for PR5957, where the problem was specifically
related to mismatches of the exception specification on the implicitly-declared
global operator new and delete. To retain that workaround, we downgrade the
error to an ExtWarn when the declaration is of a replaceable global allocation
function.
Now that this is an error, stop trying (and failing) to recover from a missing
computed noexcept specification. That recovery didn't work, and led to crashes
in code like the added testcase.
