Prior to this commit the external_source_symbol attribute wasn't supported by
#pragma clang attribute for the following two reasons:
- The Named attribute subject hasn't been supported by TableGen.
- There was no way to specify a subject match rule for #pragma clang attribute
that could operate on a set of attribute subjects (e.g. the ones that derive
from NamedDecl).
This commit fixes the two issues and thus adds external_source_symbol support to
#pragma clang attribute.

The original commit message is displayed below:
The new '#pragma clang attribute' directive can be used to apply attributes to
multiple declarations. An attribute must satisfy the following conditions to
be supported by the pragma:
- It must have a subject list that's defined in the TableGen file.
- It must be documented.
- It must not be late parsed.
- It must have a GNU/C++11 spelling.

Correct class-template deprecation behavior
Based on the comment in the test, and my reading of the standard, a deprecated warning should be issued in the following case:
template<typename T> [[deprecated]] class Foo{}; Foo<int> f;
This was not the case, because the ClassTemplateSpecializationDecl creation did not also copy the deprecated attribute.
Note: I did NOT audit the complete set of attributes to see WHICH ones should be copied, so instead I simply copy ONLY the deprecated attribute.

Summary:
When Sema looks up an attribute name, it strips off leading and trailing
"__" if the attribute is GNU-style. That is, __attribute__((foo)) and
__attribute__((__foo__)) are equivalent.
This is only true for GNU-style attributes. In particular,
__declspec(__foo__) is not equivalent to __declspec(foo), and Sema
respects this difference.
This patch fixes TableGen to match Sema's behavior. The spelling
'GNU<"__foo__">' should be normalized to 'GNU<"foo">', but
'Declspec<"__foo__">' should not be changed.
This is necessary to make CUDA compilation work on Windows, because e.g.
the __device__ attribute is spelled __declspec(__device__).
Attr.td does not contain any Declspec spellings that start or end with
"__", so this change should not affect any other attributes.

We should complain about the following:
```
void foo() __attribute__((unavailable("a", "b")));
```
Instead, we currently just ignore "b". (...We also end up ignoring "a",
because we assume elsewhere that this attribute can only have 1 or 0
args.)
This happens because `unavailable` has a fake enum arg, and
`AttributeList::{getMinArgs,getMaxArgs}` include fake args in their

Summary:
This attribute specifies expectations about the initialization of static and
thread local variables. Specifically that the variable has a
[constant initializer](http://en.cppreference.com/w/cpp/language/constant_initialization)
according to the rules of [basic.start.static]. Failure to meet this expectation
will result in an error.
Static objects with constant initializers avoid hard-to-find bugs caused by
the indeterminate order of dynamic initialization. They can also be safely
used by other static constructors across translation units.
This attribute acts as a compile time assertion that the requirements
for constant initialization have been met. Since these requirements change
between dialects and have subtle pitfalls it's important to fail fast instead
of silently falling back on dynamic initialization.
```c++
// -std=c++14
#define SAFE_STATIC __attribute__((require_constant_initialization)) static
struct T {
constexpr T(int) {}
~T();
};
SAFE_STATIC T x = {42}; // OK.
SAFE_STATIC T y = 42; // error: variable does not have a constant initializer
// copy initialization is not a constant expression on a non-literal type.
```
This attribute can only be applied to objects with static or thread-local storage
duration.

Created a visualizer for ActionResult that displayed the validity and the pointer,
but many of them initially displayed poorly. It turns out that the primary culprit
is that LocInfoType is often passed in an action result, but it is not the same
as other types. For example, LocInfoType is not in TypeNodes.def and clang::Type::TypeClass
does not have a LocInfoType enum. After adding a special visualizer for LocInfoType,
the display was more useful

Improved the visualizer for TemplateArgumentList to show type arguments in the DisplayString.

Bitsets, and the compiler features they rely on (vtable opt, CFI),
only have visibility within the LTO'd part of the linkage unit. Therefore,
only enable these features for classes with hidden LTO visibility. This
notion is based on object file visibility or (on Windows)
dllimport/dllexport attributes.
We provide the [[clang::lto_visibility_public]] attribute to override the
compiler's LTO visibility inference in cases where the class is defined
in the non-LTO'd part of the linkage unit, or where the ABI supports
calling classes derived from abstract base classes with hidden visibility
in other linkage units (e.g. COM on Windows).
If the cross-DSO CFI mode is enabled, bitset checks are emitted even for
classes with public LTO visibility, as that mode uses a separate mechanism
to cause bitsets to be exported.
This mechanism replaces the whole-program-vtables blacklist, so remove the
-fwhole-program-vtables-blacklist flag.
Because __declspec(uuid()) now implies [[clang::lto_visibility_public]], the
support for the special attr:uuid blacklist entry is removed.

This is re-landing r260742. I've reworked the conditionals so that it only hits when targeting Apple platforms with ld64.
Original Summary:
With this change generating clang order files using dtrace uses the following workflow:

ninja generate-order-file
ninja clang
This patch works by setting a default path to the order file (which can be overridden by the user). If the order file doesn't exist during configuration CMake will create an empty one.
CMake then ties up the dependencies between the clang link job and the order file, and generate-order-file overwrites CLANG_ORDER_FILE with the new order file.

This is the clang equivalent to llvm commit 264601. When using Visual Studio 2015, cmake now puts the native visualizers in llvm.sln, so the developer automatically sees custom visualizations.

When LIT parallelizes the profraw file generation we need to generate unique temp filenames then clean them up after the driver executes.
llvm-svn: 264021
With this change, the class
struct A {
A(int _i);
~A();
int foo(double d);
double bar(A *a) { return 1.3; }
};
appears in the VS2015 Locals Window as
D 0x02dbb378 struct A
|- DeclKind CXXRecord
|- Members
|- [0] implicit struct A
|- [1] Constructor {A(int _i)}
|- [2] Destructor {~A()}
|- [3] Method {int foo(double d)}
|- [4] Method {double bar(struct A *)}
|- [Raw View] /* Other stuff */
Note that these changes only benefit VS2015 as
VS2013 does not have views and only displays the
struct name "A", but the change does no apparent
harm in VS2013, so is still a win.
llvm-svn: 264020
This patch adds a new set of substitutions to the lit run lines for order files and PGO generation which run the clang driver to get the cc1 command, then execute the cc1 command directly. This allows the scripts to bypass profiling the clang driver over and over again.

Created visualizer for PointerType, LValueReferenceType, RValueReferenceType, and TemplateParmType.
In addition, cleaned up the display of existing types to be more C++-like. For example, instead of
SubstTemplateTypeParmType: {Identifier (("T"))} => Record (25), {Identifier (("A"))}
it now displays more readably as
SubstTemplateTypeParmType: {typename T <= struct A}
The <expand> sections still can be used for all the gory details if necessary.
llvm-svn: 263638
This is one of a series of changes to improve the MSVC visualization of Clang types.
This one focuses on Record and SubstTemplateTypeParmType meaning that, for example,
a TemplateArgumentLoc no longer displays incomprehensibly in the locals window as
{Argument={DeclArg={Kind=1 QT=0x033acb00 D=0xcccccccc {DeclType=???}}...
but instead much more usefully as
Type template parameter: SubstTemplateTypeParm: {Identifier (("T"))} => Record, {Identifier (("A"))}
Additional types and improvements will be made in subsequent commits

exactly the same as clang's existing [[clang::fallthrough]] attribute, which
has been updated to have the same semantics. The one significant difference
is that [[fallthrough]] is ill-formed if it's not used immediately before a
switch label (even when -Wimplicit-fallthrough is disabled). To support that,
we now build a CFG of any function that uses a '[[fallthrough]];' statement
to check.
In passing, fix some bugs with our support for statement attributes -- in
particular, diagnose their use on declarations, rather than asserting.

This appears to be passing '-Wl,-order_file' to Linux link commands,
which then causes the linker to silently, behind the scenes, write the

people who can't get Clang to update when they build because of this.

Summary:
This patch extends the lit-based perf-training tooling supplied for PGO data generation to also generate linker order files using dtrace.
This patch should work on any system that has dtrace. If CMake can find the dtrace tool it will generate a target 'generate-order-file' which will run the per-training tests wrapped by dtrace to capture function entries. There are several algorithms implemented for sorting the order files which can be experimented with for best performance. The dtrace wrapper also supports bot oneshot and pid probes.
The perf-helper.py changes to support order file construction are ported from internal changes by ddunbar; he gets all the credit for the hard work here, I just copy and pasted.
Note: I've tested these patches on FreeBSD and OS X 10.10.

This patch adds support for using LIT to drive generating PGO profile data for clang.
This first pass implementation should work on Linux and Unix based platforms. If you build clang using CMake with LLVM_BUILD_INSTRUMENTED=On the CMake build generates a generate-profdata target that will use the just-built clang to build any test files (see hello_world.cpp as an example). Each test compile will generate profraw files for each clang process. After all tests have run CMake will merge the profraw files using llvm-profdata.
Future opportunities for extension:
* Support for Build->Profile->Build bootstrapping
* Support for linker order file generation using a similar mechanism and the same training data
* Support for Windows

Currently the SATestBuild.py and SATestAdd.py buildbot scripts expect project
sources to be checked into the project repository. This commit changes these
scripts to additionally support a model where project sources are downloaded
rather than checked into the repository. Sometimes projects may need to be
modified (for example, to support a newer versions of clang), so the updated scripts
also allow for an optional patch file that will be applied to the downloaded
project source before analysis.
To support this workflow, this commit changes the expected layout of
a project in the repository. The project-specific helper scripts will stay
in the root of each project directory, but the benchmark source itself (if
checked into the repo) should now be stored in a subdirectory named
'CachedSource':
project_name/
cleanup_run_static_analyzer.sh [optional]
run_static_analyzer.cmd [required]
download_project.sh [optional]
CachedSource/ [optional]
changes_for_analyzer.patch [optional]
If the 'CachedSource' source directory is not present, the download script will
be executed. This script should download the project source into 'CachedSource'.
Then, if 'changes_for_analyzer.patch' is present its changes will
be applied to a copy of 'CachedSource' before analysis.

Fake arguments are automatically handled for serialization, cloning,

This is chiefly useful for attributes that can be written by the
