c05ca5e40c DiagnoseUnknownTypename always emits a diagnostic and returns true
Make it return void and delete the dead code in the parser that handled
the case where it might return false.  This has been dead since 2010
when John deleted Action.h.

fe781458d8 MS static locals mangling: don't count enum scopes
We may not have the mangling for static locals vs. enums completely figured out,
but at least for my simple test cases, enums should not increment the mangling
number.

df6e4a06e4 Delay lookup of simple default template arguments under -fms-compatibility
MSVC delays parsing of default arguments until instantiation.  If the
default argument is never used, it is never parsed.  We don't model
this.

Instead, if lookup of a type name fails in a template argument context,
we form a DependentNameType, which will be looked up at instantiation
time.

This fixes errors about 'CControlWinTraits' in atlwin.h.

fdd783a501 Unify __declspec attribute argument parsing with the common attribute argument parsing code.
This removes a diagnostic that is no longer required (the semantic engine now properly handles attribute syntax so __declspec and __attribute__ spellings no longer get mismatched). This caused several testcases to need updating for a slightly different wording.

757fcd6d1f [cleanup] Re-sort includes with llvm/utils/sort_includes.py and fix
a missing include from CLog.h.

CLog.h referenced most of the core libclang types but never directly
included Index.h that provides them. Previously it got lucky and other
headers were always included first but with the sorting it ended up
first in one case and stopped compiling. Adding the Index.h include
fixes it right up.

fa1d4e1067 Do not add enums to prototype scope in C++ modes.
The language forbids defining enums in prototypes, so this check is normally
redundant, but if an enum is defined during template instantiation it should
not be added to the prototype scope.

While at it, clean up the code that deals with tag definitions in prototype
scope and expand the visibility warning to cover the case where an anonymous
enum is defined.

67b44c9871 Enable correcting a member declaration where the type is class template,
and the class name is shadowed by another member. Recovery still needs
to be figured out, which is non-trivial since the parser has already gone
down a much different path than if it had recognized the class template
as type instead of seeing the member that shadowed the class template.

c669cc0d77 Add a new attribute meta-spelling called "GCC" -- it widens into being a GNU spelling, and a CXX11 spelling with the namespace "gnu". It also sets a bit on the spelling certifying that it is known to GCC. From this, we can warn about the extension appropriately. As a consequence, the FunctionDefinition functionality is completely removed.

9a99e0da5a Remove some hard-coded specialness for thread-safety attributes from the parser, and made it more declarative. If an attribute is allowed to appear on a function definition when late parsed, it can now use the FunctionDefinition attribute subject. It's treated as a FunctionDecl for most purposes, except it also gets exposed on the AttributeList so that it can be used while parsing.

383d2c478c ExpectAndConsume: Diagnose errors automatically
1) Teach ExpectAndConsume() to emit expected and expected-after diagnostics
    using the generic diagnostic descriptions added in r197972, eliminating another
    set of trivial err_expected_* variations while maintaining existing behaviour.

 2) Lift SkipUntil() recovery out of ExpectAndConsume(). The Expect/Consume
    family of functions are primitive parser operations that now have the
    well-defined property of operating on single tokens. Factoring out recovery
    exposes opportunities for more consistent and tailored error recover at the
    call sites instead of just relying on a bottled SkipUntil formula.

ec543279db Support and use token kinds as diagnostic arguments
Introduce proper facilities to render token spellings using the diagnostic
formatter.

Replaces most of the hard-coded diagnostic messages related to expected tokens,
which all shared the same semantics but had to be multiply defined due to
variations in token order or quote marks.

The associated parser changes are largely mechanical but they expose
commonality in whole chunks of the parser that can now be factored away.

This commit uses C++11 typed enums along with a speculative legacy fallback
until the transition is complete.

Requires corresponding changes in LLVM r197895.

f22856a415 Remove OpenCL-specific type keywords and specifiers
This commit kills off custom type specifier and keyword handling of OpenCL C
data types.

Although the OpenCL spec describes them as keywords, we can handle them more
elegantly as predefined types. This should provide better error correction and
code completion as well as simplifying the implementation.

The primary intention is however to simplify the C/C++ parser and save some
packed bits on AST structures that had been extended in r170432 just for
OpenCL.

   appropriate ConsumeCodeCompletionToken() function.

47642d2b7e Emit an extension warning when changing system header tokens
clang converts keywords to identifiers for compatibility with various system
headers such as GNU libc.

Implement a -Wkeyword-compat extension warning to diagnose those cases. The
warning is on by default but will generally be ignored in system headers. It
can however be enabled globally to aid standards conformance testing.

This also changes the __uptr keyword avoidance from r195710 to no longer
special-case system headers, bringing it in line with other similar workarounds
in clang.

Implementation returns bool for symmetry with token annotation functions.

Some examples:

warning: keyword '__is_pod' will be treated as an identifier for the remainder of the translation unit [-Wkeyword-compat]
struct __is_pod

warning: keyword '__uptr' will be treated as an identifier here [-Wkeyword-compat]
union w *__uptr;
