Fixes processing of declarative directives and standalone executable directives. Declarative directives should not be allowed as an immediate statements and standalone executable directives are allowed to be used in case-stmt constructs.

1) When dumping a declaration that declares a name for a type, also dump the named type.
2) Add a #pragma clang __debug dump X, that dumps the lookup results for X in
the current context.

Support for OpenCL 2.0 pipe type.

An undecorated function designator implies taking the address of a function,
which is illegal in OpenCL. Implementing a check for this earlier to allow
the error to be reported even in the presence of other more obvious errors.

OpenMP 4.0-3.1 supports the next format of ‘schedule’ clause: schedule(kind[, chunk_size])
Where kind can be one of ‘static’, ‘dynamic’, ‘guided’, ‘auto’ or ‘runtime’.
OpenMP 4.5 defines the format: schedule([modifier [, modifier]:]kind[, chunk_size])
Modifier can be one of ‘monotonic’, ‘nonmonotonic’ or ‘simd’.
llvm-svn: 256487
OpenMP 4.5 adds 'depend(source)' clause for 'ordered' directive to support cross-iteration dependence. Patch adds parsing and semantic analysis for this construct.

called on an empty list.
This commit makes Parser::parseObjCTypeParamListOrProtocolRefs return
nullptr if it sees an invalid type parameter (e.g., __kindof) in the
type parameter list.

Clang doesn’t support a use of “this” pointer inside inline asm.
When I tried to compile a class or a struct (see example) with an inline asm that contains "this" pointer.
Clang returns with an error.
This patch fixes that.
error: expected unqualified-id
For example:
'''
struct A {
void f() {
__asm mov eax, this
// error: expected unqualified-id
}
};
'''

r251874 stopped back-patching the AST when an Objective-C 'readonly'
property is redeclared in a class extension as 'readwrite'. However,
it did not properly handle merging of Objective-C property attributes
(e.g., getter name, ownership, atomicity) to the redeclaration,
leading to bad metadata. Merge (and check!) those property attributes
so we get the right metadata and reasonable ASTs. Fixes

OpenMP 4.5 adds directives 'taskloop' and 'taskloop simd'. These directives support clause 'num_tasks'. Patch adds parsing/semantic analysis for this clause.
llvm-svn: 255008
OpenMP 4.5 adds 'taksloop' and 'taskloop simd' directives, which have 'grainsize' clause. Patch adds parsing/sema analysis of this clause.

OpenMP 4.5 adds 'taskloop' and 'taskloop simd' directives. These directives have new 'nogroup' clause. Patch adds basic parsing/sema support for this clause.
llvm-svn: 254899
OpenMP 4.5 defines new clause 'priority' for 'task', 'taskloop' and 'taskloop simd' directives. Added parsing and sema analysis for 'priority' clause in 'task' and 'taskloop' directives.

This patch adds support of #pragma vtordisp inside functions in attempt to improve compatibility. Microsoft compiler appears to save the stack of vtordisp modes on entry of struct methods' bodies and restore it on exit (method-local vtordisp).

Also address a typo from a prior patch that performed a similar fix during Parsing of default non-type template arguments. I left the RAII ExpressionEvaluationContext variable Name as Unevaluated though we had switched the context to ConstantEvaluated.
There should be no functionality change here - since when expression evaluation context is popped off, for the most part these two contexts currently behave similarly in regards to lambda diagnostics and odr-use tracking.
Like its parsing counterpart, this patch presages the advent of constexpr lambda patches...
llvm-svn: 253590
This patch emits a more appropriate (but still noisy) diagnostic stream when a lambda-expression is encountered within a non-type default argument.
For e.g. template<int N = ([] { return 5; }())> int f();
As opposed to complaining that a lambda expression is not allowed in an unevaluated operand, the patch complains about the lambda being forbidden in a constant expression context (which will be allowed in C++17 now that they have been accepted by EWG, unless of course CWG or national bodies (that have so far shown no signs of concern) rise in protest)
As I start submitting patches for constexpr lambdas (http://wg21.link/P0170R0) under C++1z (OK'd by Richard Smith at Kona), this will be one less change to make.
Thanks!

other than the top level, we issue an error. This breaks a fair amount of C++
code wrapping C libraries, where the C library is #included within a namespace
/ extern "C" combination, because the C library (probably) includes C++
standard library headers which may be within modules.
Without modules, this setup is harmless if (and *only* if) the corresponding
standard library module was already included outside the namespace, so
downgrade the error to a default-error extension in that case, so that it can
be selectively disabled for such misbehaving libraries.

Differences from the GCC extension:
* __auto_type is also permitted in C++ (but only in places where
it could appear in C), allowing its use in headers that might
be shared across C and C++, or used from C++98
* __auto_type can be combined with a declarator, as with C++ auto
(for instance, "__auto_type *p")
* multiple variables can be declared in a single __auto_type
declaration, with the C++ semantics (the deduced type must be
the same in each case)
This patch also adds a missing restriction on applying typeof to
a bit-field, which GCC has historically rejected in C (due to
lack of clarity as to whether the operand should be promoted).
The same restriction also applies to __auto_type in C (in both
GCC and Clang).
This also fixes PR25449.
