Douglas Gregor 205d044552 Switch diagnostic text from "C++0x" over to "C++11".
We'd also like for "C++11" or "c++11" to be used for the warning
groups, but without removing the old warning flags. Patches welcome;
I've run out of time to work on this today.

Douglas Gregor 728d00b8e7 Parse the initializer for a class member after handling its
declarator, so that the declarator is in scope for the
initializer. Fixes PR9989.

Richard Smith 2316cd8b79 constexpr: semantic checking for constexpr variables.
We had an extension which allowed const static class members of floating-point type to have in-class initializers, 'as a C++0x extension'. However, C++0x does not allow this. The extension has been kept, and extended to all literal types in C++0x mode (with a fixit to add the 'constexpr' specifier).

Chris Lattner 53fa04909c make clang print types as "const int *" instead of "int const*",
which is should have done from the beginning.  As usual, the most
fun with this sort of change is updating all the testcases.

Douglas Gregor 428119e39a When parsing cached C++ method declarations/definitions, save the
"previous token" location at the end of the class definition. This
eliminates a badly-placed error + Fix-It when the ';' following a
class definition is missing. Fixes <rdar://problem/8066414>.

Douglas Gregor f19ac0ede9 Downgrade the "declaration does not declare anything" error to a
warning. It's not harmful to have such pointless declarations, and GCC
does not diagnose this issue consistently.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Douglas Gregor 0c88030abd Move most of the checking from ActOnCXXMemberDeclarator to other, more general routines. This is a step toward separating the checking logic from Declarators, which in turn is required for template instantiation.

rules are slightly different than in C, and now we handle both
dialects properly.

Douglas Gregor 82ac25e4a7 Unify the code for defining tags in C and C++, so that we always
introduce a Scope for the body of a tag. This reduces the number of
semantic differences between C and C++ structs and unions, and will
help with other features (e.g., anonymous unions) in C. Some important
points:

  - Fields are now in the "member" namespace (IDNS_Member), to keep
    them separate from tags and ordinary names in C. See the new test
    in Sema/member-reference.c for an example of why this matters. In
    C++, ordinary and member name lookup will find members in both the
    ordinary and member namespace, so the difference between
    IDNS_Member and IDNS_Ordinary is erased by Sema::LookupDecl (but
    only in C++!). 
  - We always introduce a Scope and push a DeclContext when we're
    defining a tag, in both C and C++. Previously, we had different
    actions and different Scope/CurContext behavior for enums, C
    structs/unions, and C++ structs/unions/classes. Now, it's one pair
    of actions. (Yay!)

There's still some fuzziness in the handling of struct/union/enum
definitions within other struct/union/enum definitions in C. We'll
need to do some more cleanup to eliminate some reliance on CurContext
before we can solve this issue for real. What we want is for something
like this:

  struct X {
    struct T { int x; } t;
  };

to introduce T into translation unit scope (placing it at the
appropriate point in the IdentifierResolver chain, too), but it should
still have struct X as its lexical declaration
context. PushOnScopeChains isn't smart enough to do that yet, though,
so there's a FIXME test in nested-redef.c

Argyrios Kyrtzidis 1207d31952 Fix a bug that crashed clang when parsing this:
class C {
  static const int number = 50;
  static int arr[number];
};

Here's how it worked:
-GetTypeForDeclarator was called from both Sema::ActOnCXXMemberDeclarator and Sema::ActOnDeclarator.
-VariableArrayTypes are not uniqued so two VariableArrayTypes were created with the same DeclRefExpr.
-On exit they both tried to destroy that one DeclRefExpr.

The fix is not to use GetTypeForDeclarator from the Sema::ActOnCXXMemberDeclarator.
