David Majnemer 86b1bfad05 [Sema] Warn when alignof is used with __builtin_alloca_with_align
The second argument to __builtin_alloca_with_align is supposed to be in
bits, not bytes.  Using alignof there would be indicative of a bug.

Artem Dergachev aacc03c918 [analyzer] MacOSXAPIChecker: Disallow dispatch_once_t in ivars and heap.
Unlike global/static variables, calloc etc. functions that allocate ObjC
objects behave differently in terms of memory barriers, and hacks that make
dispatch_once as fast as it possibly could be start failing.

Michael Zuckerman 849a6a5e5a [x86][inline-asm][AVX512][clang][PART-1] Introducing "k" and "Yk" constraints for extended inline assembly, enabling use of AVX512 masked vectorized instructions.
Commit on behalf of mharoush

Extending inline assembly support, compatible with GCC as folowing:
 "k" constraint hints the compiler to select any of AVX512 k0-k7 registers.
 "Yk" constraint is a subset of "k" excluding k0 which is not allowd to be used as a mask.

Michael Zuckerman 2460bada56 [x86][inline-asm] Add support for curly brackets escape using "%" in extended inline asm.
Commit on behalf of mharoush

After LGTM and check all:

This patch is a compatibility fix for clang, matching GCC support for charter escape when using extended in-line assembly (i.e, "%{" ,"%}" --> "{" ,"}" ).
 It is meant to enable support for advanced features such as AVX512 conditional\masked vector instructions/broadcast assembly syntax.

Ulrich Weigand 30354ebb00 [SystemZ] Add -march=archX aliases
For compatibility with other compilers on the platform, allow specifying
levels of the z/Architecture instead of model names with -march.  In
particular, the following aliases are now supported:

  -march=arch8   equals  -march=z10
  -march=arch9   equals  -march=z196
  -march=arch10  equals  -march=zEC12
  -march=arch11  equals  -march=z13

This parallels the equivalent (and prerequisite) LLVM change in r285577.

Justin Lebar 2b42ccc78b [CUDA] [AST] Allow isInlineDefinitionExternallyVisible to be called on functions without bodies.
Summary:
In CUDA compilation, we call isInlineDefinitionExternallyVisible (via
getGVALinkageForFunction) on functions while parsing their definitions.

At the point in time when we call getGVALinkageForFunction, we haven't
yet added the body to the function, so we trip this assert.  But as far
as I can tell, this is harmless.

To work around this, we add a new flag to FunctionDecl, "WillHaveBody".

There was other code that was working around the existing assert with a
really awful hack -- this change lets us get rid of that hack.

Alex Lorenz a8c44ba2c0 [Objective-C] Add objc_subclassing_restricted attribute
This patch adds an objc_subclassing_restricted attribute into clang. This
attribute acts similarly to 'final' - Objective-C classes with this attribute
can't be subclassed. However, @interface declarations that have
objc_subclassing_restricted but don't have @implementation are allowed to
inherit other @interface declarations with objc_subclassing_restricted. This is
needed to describe the Swift class hierarchy in clang while making sure that
the Objective-C classes cannot subclass the Swift classes.

This attribute is already implemented in a fork of clang that's used for Swift
(https://github.com/apple/swift-clang) and this patch moves that code to the
upstream clang repository.

If we pass a header to libclang, e.g. because it's open in an editor in

Clang should emit a warning to warn users this is not a good practice

Richard Trieu 42b98e2a82 Fix a crash on invalid code.
The diagnostic was attempting to access the QualType of a TypeDecl by calling
TypeDecl::getTypeForDecl.  However, the Type pointer stored there is lazily
loaded by functions in ASTContext.  In most cases, the pointer is loaded and
this does not cause a problem.  However, when more that 50 or so unknown types
are seen beforehand, this causes the Type to not be loaded, passing a null
Type to the diagnostics, leading to the crash.  Using
ASTContext::getTypeDeclType will give a proper QualType for all cases.
