This is a fix for https://llvm.org/bugs/show_bug.cgi?id=25561 which was a
crash on invalid.  Change the handling of invalid decls to have a catch-all
case to prevent unexpecting decls from triggering an assertion.

Justin Lebar d3a44f6885 [CUDA] Add -fcuda-flush-denormals-to-zero.
Summary:
Setting this flag causes all functions are annotated with the
"nvvm-f32ftz" = "true" attribute.

In addition, we annotate the module with "nvvm-reflect-ftz" set
to 0 or 1, depending on whether -cuda-flush-denormals-to-zero is set.
This is read by the NVVMReflect pass.

Summary:
The parsing logic has been separated out from the macro implementation logic, leading to a number of improvements:

* Gracefully handle unexpected/invalid tokens, too few, too many and nested parameters
* Provide consistent behaviour between all built-in feature-like macros
* Simplify the implementation of macro logic
* Fix __is_identifier to correctly return '0' for non-identifiers

Carlo Bertolli c687225b43 [OPENMP] Codegen for teams directive for NVPTX
This patch implements the teams directive for the NVPTX backend. It is different from the host code generation path as it:

Does not call kmpc_fork_teams. All necessary teams and threads are started upon touching the target region, when launching a CUDA kernel, and their execution is coordinated through sequential and parallel regions within the target region.
Does not call kmpc_push_num_teams even if a num_teams of thread_limit clause is present. Setting the number of teams and the thread limit is implemented by the nvptx-related runtime.
Please note that I am now passing a Clang Expr * to emitPushNumTeams instead of the originally chosen llvm::Value * type. The reason for that is that I want to avoid emitting expressions for num_teams and thread_limit if they are not needed in the target region.

Douglas Gregor 24ae22c047 [Objective-C] Introduce objc_runtime_visible attribute.
The objc_runtime_visible attribute deals with an odd corner case where
a particular Objective-C class is known to the Objective-C runtime
(and, therefore, accessible by name) but its symbol has been hidden
for some reason. For such classes, teach CodeGen to use
objc_lookUpClass to retrieve the Class object, rather than referencing
the class symbol directly.

Classes annotated with objc_runtime_visible have two major limitations
that fall out from places where Objective-C metadata needs to refer to
the class (or metaclass) symbol directly:

* One cannot implement a subclass of an objc_runtime_visible class.
* One cannot implement a category on an objc_runtime_visible class.

Implements rdar://problem/25494092.

In ObjCMethodCall:getRuntimeDefinition(), if the method is an accessor in a

category, which causes a crash when trying to synthesize a getter for the

Akira Hatanaka 68ab7fe1c8 [CodeGenCXX] Fix ItaniumCXXABI::getAlignmentOfExnObject to return 8-byte
alignment on Darwin.

Itanium C++ ABI specifies that _Unwind_Exception should be double-word
aligned (16B). To conform to the ABI, libraries implementing exception
handling declare the struct with __attribute__((aligned)), which aligns
the unwindHeader field (and the end of __cxa_exception) to the default
target alignment (which is typically 16-bytes).

struct __cxa_exception {
  ...
  // struct is declared with __attribute__((aligned)).
  _Unwind_Exception unwindHeader;
};

Based on the assumption that _Unwind_Exception is declared with
__attribute__((aligned)), ItaniumCXXABI::getAlignmentOfExnObject returns
the target default alignment for __attribute__((aligned)). It turns out
that libc++abi, which is used on Darwin, doesn't declare the struct with
the attribute and therefore doesn't guarantee that unwindHeader is
aligned to the alignment specified by the ABI, which in some cases
causes the program to crash because of unaligned memory accesses.

This commit avoids crashes due to unaligned memory accesses by having
getAlignmentOfExnObject return an 8-byte alignment on Darwin. I've only
fixed the problem for Darwin, but we should also figure out whether other
platforms using libc++abi need similar fixes.

George Burgess IV 21d3bffe29 [Sema] Fix PR27122: ICE with enable_if+ill-formed call.
In some cases, when we encounter a direct function call with an
incorrect number of arguments, we'll emit a diagnostic, and pretend that
the call to the function was valid. For example, in C:

int foo();
int a = foo(1);

Prior to this patch, we'd get an ICE if foo had an enable_if attribute,
because CheckEnableIf assumes that the number of arguments it gets
passed is valid for the function it's passed. Now, we check that the
number of args looks valid prior to checking enable_if conditions.

This fix was not done inside of CheckEnableIf because the problem
presently can only occur in one caller of CheckEnableIf (ActOnCallExpr).
Additionally, checking inside of CheckEnableIf would make us emit
multiple diagnostics for the same error (one "enable_if failed", one
"you gave this function the wrong number of arguments"), which seems
worse than just complaining about the latter.

Bruno Cardoso Lopes e62cfd7c17 [CrashReproducer] Add a module map callback for added headers
The current ModuleDependencyCollector has a AST listener to collect
header files present in loaded modules, but this isn't enough to collect
all headers needed in the crash reproducer. One of the reasons is that
the AST writer doesn't write symbolic link header paths in the pcm modules,
this makes the listeners on the reader only able to collect the real files.

Since the module maps could contain submodules that use headers which
are symbolic links, not collecting those forbid the reproducer scripts
to regen the modules.

For instance:

usr/include/module.map:
  ...
  module pthread {
    header "pthread.h"
    export *

    module impl {
      header "pthread_impl.h"
      export *
    }
  }
  ...

usr/include/pthread/pthread_impl.h
usr/include/pthread_impl.h -> pthread/pthread_impl.h

The AST dump for the module above:

  <SUBMODULE_HEADER abbrevid=6/> blob data = 'pthread_impl.h'
  <SUBMODULE_TOPHEADER abbrevid=7/> blob data = '/<path_to_sdk>/usr/include/pthread/pthread_impl.h'

Note that we don't have "usr/include/pthread_impl.h" which is requested
by the module.map in case we want to reconstruct the module in the
reproducer. The reason the original symbolic link path isn't used is
because the headers are kept by name and requested through the
FileManager, which unique files and returns the real path only.

To fix that, add a callback to be invoked everytime a header is added
while parsing module maps and hook that up to the module dependecy
collector. This callback is only registered when generating the
reproducer.

Justin Lebar ba122ab42f [CUDA] Make unattributed constexpr functions implicitly host+device.
With this patch, by a constexpr function is implicitly host+device
unless:

 a) it's a variadic function (variadic functions are not allowed on the
    device side), or
 b) it's preceeded by a __device__ overload in a system header.

The restriction on overloading __host__ __device__ functions on the
basis of their CUDA attributes remains in place, but we use (b) to allow
us to define __device__ overloads for constexpr functions in cmath,
which would otherwise be __host__ __device__ and thus not overloadable.

You can disable this behavior with -fno-cuda-host-device-constexpr.

Justin Lebar 0cda764430 [CUDA] Add math forward declares to CUDA header wrapper.
Summary:
This is necessary for a future patch which will make all constexpr
functions implicitly host+device.  cmath may declare constexpr
functions, but these we do *not* want to be host+device.  The forward
declares added in this patch prevent this (because the rule will be,
constexpr functions become implicitly host+device unless they're
preceeded by a decl with __device__).

Oleg Ranevskyy b88d2474df [Clang][ARM] __va_list declaration is not saved in ASTContext causing compilation error or crash
Summary:
When the code is compiled for arm32 and the builtin `__va_list` declaration is created by `CreateAAPCSABIBuiltinVaListDecl`, the declaration is not saved in the `ASTContext` which may lead to a compilation error or crash.

Minimal reproducer I was able to find:
**header.h**
```
#include <stdarg.h>
typedef va_list va_list_1;
```

**test.cpp**
```
typedef __builtin_va_list va_list_2;
void foo(const char* format, ...) { va_list args; va_start( args, format ); }
```

Steps to reproduce:
```
clang -x c++-header --target=armv7l-linux-eabihf header.h
clang -c -include header.h --target=armv7l-linux-eabihf test.cpp
```

Compilation error:
```
error: non-const lvalue reference to type '__builtin_va_list'
      cannot bind to a value of unrelated type 'va_list' (aka '__builtin_va_list')
```

Compiling the same code as a C source leads to a crash:
```
clang --target=armv7l-linux-eabihf header.h
clang -c -x c -include header.h --target=armv7l-linux-eabihf test.cpp
```

Vassil Vassilev 262f41e91c [modules] Write out identifiers if the ID is local, too.
In some cases a slot for an identifier is requested but it gets written to
another module, causing an assertion.

At the point when we start serializing Rtypes, we have no imported IdentifierID
for float_round_style. We start serializing stuff and allocate an ID for it.
Then, during the serialization process, we pull in the identifier info for it
from TSchemaHelper. Finally, WriteIdentifierTable decides that the identifier
has not changed since it was deserialized, so doesn't emit it.

Gabor Horvath 1b654f2293 [ASTMatchers] Existing matcher hasAnyArgument fixed
Summary: A checker (will be uploaded after this patch) needs to check implicit casts. The checker needs matcher hasAnyArgument but it ignores implicit casts and parenthesized expressions which disables checking of implicit casts for arguments in the checker. However the documentation of the matcher contains a FIXME that this should be removed once separate matchers for ignoring implicit casts and parenthesized expressions are ready. Since these matchers were already there the fix could be executed. Only one Clang checker was affected which was also fixed (ignoreParenImpCasts added) and is separately uploaded. Third party checkers (not in the Clang repository) may be affected by this fix so the fix must be emphasized in the release notes.

Alexey Bataev 587e1de4ea [OPENMP 4.0] Initial support for '#pragma omp declare simd' directive.
Initial parsing/sema/serialization/deserialization support for '#pragma
omp declare simd' directive.
The 'declare simd' construct can be applied to a function to enable the
creation of one or more versions that can process multiple arguments
using SIMD instructions from a single invocation from a SIMD loop.
If the function has any declarations, then the declare simd construct
for any declaration that has one must be equivalent to the one specified
 for the definition. Otherwise, the result is unspecified.
This pragma can be applied many times to the same declaration.
Internally this pragma is represented as an attribute. But we need special processing for this pragma because it must be used before function declaration, this directive is applied to.

Over the last month we've been testing SafeStack extensively. As far as
we know, it works perfectly fine. That why I'd like to see us having
this enabled by default for CloudABI.

This change introduces a getDefaultSanitizers() function that toolchains
can use to specify which sanitizers are enabled by default. Once all
flags are processed, only flags that had no -fno-sanitize overrides are
enabled.

Extend the thests for CloudABI to test both the default case and the
case in which we want to explicitly disable SafeStack.
