Hans Wennborg c9bd88e681 Remove the -cxx-abi command-line flag.
This makes the C++ ABI depend entirely on the target: MS ABI for -win32 triples,
Itanium otherwise. It's no longer possible to do weird combinations.

To be able to run a test with a specific ABI without constraining it to a
specific triple, new substitutions are added to lit: %itanium_abi_triple and
%ms_abi_triple can be used to get the current target triple adjusted to the
desired ABI. For example, if the test suite is running with the i686-pc-win32
target, %itanium_abi_triple will expand to i686-pc-mingw32.

Hans Wennborg 2545efe20c Better diagnostic for static override when methods are thiscall by default
Methods are thiscall by default in the MS ABI, and also in MinGW targetting GCC 4.7 or later.

This changes the diagnostic from the technically correct but hard to understand:

  virtual function 'foo' has different calling convention attributes ('void ()') than the function it overrides (which has calling convention 'void () __attribute__((thiscall))')

to the more intuitive and also correct:

  'static' member function 'foo' overrides a virtual function

We already have a test for this. Let's just run it in both ABI modes.

Richard Smith 9ca5c42582 Update all tests other than Driver/std.cpp to use -std=c++11 rather than
-std=c++0x. Patch by Ahmed Charles!

Chandler Carruth 98e3c568bf Fix PR8767, improve diagnostic wording when allocating an object of an
abstract class type.

Patch by Stephen Hines, with a wording tweak from Doug applied by me.

John McCall c146582e60 When parsing an out-of-line member function declaration, we must delay
access-control diagnostics which arise from the portion of the declarator
following the scope specifier, just in case access is granted by
friending the individual method.  This can also happen with in-line
member function declarations of class templates due to templated-scope
friend declarations.

We were really playing fast-and-loose before with this sort of thing,
and it turned out to work because *most* friend functions are in file
scope.  Making us delay regardless of context exposed several bugs with
how we were manipulating delay.  I ended up needing a concept of a
context that's independent of the declarations in which it appears,
and then I actually had to make some things save contexts correctly,
but delay should be much cleaner now.

I also encapsulated all the delayed-diagnostics machinery in a single
subobject of Sema;  this is a pattern we might want to consider rolling
out to other components of Sema.

Chandler Carruth a92409c3ec Enhance the diagnostic for negative array sizes to include the
declaration name of the array when present. This ensures that
a poor-man's C++03 static_assert will include the user error message
often embedded in the name.

Update all the tests to reflect the new wording, and add a test for the
name behavior.

John McCall 3155f573f5 Turn access control on by default in -cc1.
Remove -faccess-control from -cc1; add -fno-access-control.
Make the driver pass -fno-access-control by default.
Update a bunch of tests to be correct under access control.

John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

they are re-checked on instantiation.

at intermediate points along the inheritance path.  Prepare for friends.

Anders Carlsson 7caa4cb87a No need to canonicalize the type and use dyn_cast. Also, correctly diagnose trying to override a function returning an lvalue reference with a function overriding an rvalue reference.

Chandler Carruth df7fd5f8d5 Fix an obvious goof that caused us to only see the top level of return types
when checking for covariance. Added some fun test cases, fixes PR6110.

This felt obvious enough to just commit. ;] Let me know if anything needs
tweaking.

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 c99f155365 Unify the end-of-class code paths used by the parser and template
instantiation, to ensure that we mark class template specilizations as
abstract when we need to and perform checking of abstract classes.

Also, move the checking that determines whether we are creating a
variable of abstract class type *after* we check whether the type is
complete. Otherwise, we won't see when we have an abstract class
template specialization that is implicitly instantiated by this
declaration. This is the "something else" that Sebastian had noted
earlier.

Douglas Gregor 6be3de3fa7 Funtion templates and function template specializations do not
override virtual functions. Also, eliminate a (now redundant) call to
AddOverriddenMethods.

Douglas Gregor 21920e3758 Move the checking of overridden virtual functions into the code path
common to both parsing and template instantiation, so that we'll find
overridden virtuals for member functions of class templates when they
are instantiated. 

Additionally, factor out the checking for pure virtual functions, so
that it will be executed both at parsing time and at template
instantiation time. 

These changes fix PR5656 (for real), although one more tweak
w.r.t. member function templates will be coming along shortly.
