Fariborz Jahanian 2b9fc83db5 Fixes a code gen bug related to accessing a now
non-existing 'isa' field of a non-existing struct type
all related to legacy type definition for 'id' which we have
dropped in clang in favor of a built-in type.
(fixes radar 7470820).

Anders Carlsson 714d0969b3 If a ParmVarDecl's default argument is a CXXExprWithTemporaries, return the underlying expr instead. Add getNumDefaultArgTemporaries and getDefaultArgTemporary which returns the temporaries a default arg creates.

Nate Begeman ac8183a830 Support OpenCL 1.1 odd-length vector component accessors.
For hi/odd of an odd-length vector, the last component is undefined.  Since
we shuffle with an undef vector, no CodeGen needs to change to support this.

Douglas Gregor fab31f47b2 When certain diagnostics involving run-time behavior would be emitted
in a potentially potentially evaluated context, queue those
diagnostics and only emit them if the context ends up being
potentially evaluated. This completes the fix for PR5761.

Douglas Gregor 7ca84af48e Suppress warnings and errors about certain uses of non-POD types (in
__builtin_offsetof, passing through an ellipsis) when we're in an
unevaluated context. This is the first part of the fix to PR5761,
which deals with the simple case of an unevaluated context.

John McCall cd4b47747b Stop trying to analyze class-hierarchies for dependently-scoped id-expressions;
there's nothing interesting we can say now that we're correctly not requiring
the qualifier to name a known base class in dependent contexts.

Require scope specifiers on member access expressions to name complete types
if they're not dependent;  delay lookup when they are dependent.

Use more appropriate diagnostics when qualified implicit member access
expressions find declarations from unrelated classes.

John McCall 2d74de9632 Rework how we support C++ implicit member accesses. If we can resolve an
implicit member access to a specific declaration, go ahead and create
it as a DeclRefExpr or a MemberExpr (with implicit CXXThisExpr base) as
appropriate.  Otherwise, create an UnresolvedMemberExpr or
DependentScopeMemberExpr with a null base expression.

By representing implicit accesses directly in the AST, we get the ability
to correctly delay the decision about whether it's actually an instance
member access or not until resolution is complete.  This permits us
to correctly avoid diagnosing the 'problem' of 'MyType::foo()'
where the relationship to the type isn't really known until instantiation.

Douglas Gregor e7488b904c Don't automatically assume that an id-expression refers to a
ValueDecl, because that isn't always the case in ill-formed
code. Diagnose a common mistake (forgetting to provide a template
argument list for a class template, PR5655) and dyn_cast so that we
handle the general problem of referring to a non-value declaration
gracefully.

John McCall 10eae1851d Eliminate the use of OverloadedFunctionDecl in member expressions.
Create a new UnresolvedMemberExpr for these lookups.  Assorted hackery
around qualified member expressions;  this will all go away when we

Alexis Hunt 3d221f2fce Add DeclarationName support for C++0x operator literals. They should now work as

Douglas Gregor ff790f15c4 Refactor our handling of expression evaluation contexts, so that Sema
maintains a stack of evaluation contexts rather than having the parser
do it. This change made it simpler to track in which contexts
temporaries were created, so that we could...

"Forget" about temporaries created within unevaluated contexts, so
that we don't build a CXXExprWithTemporaries and, therefore, destroy
the integral-constness of our expressions. Fixes PR5609.

John McCall e66edc18ae Rip out TemplateIdRefExpr and make UnresolvedLookupExpr and
DependentScopeDeclRefExpr support storing templateids.  Unite the common   
code paths between ActOnDeclarationNameExpr and ActOnTemplateIdExpr.

This gets us to a point where we don't need to store function templates in
the AST using TemplateNames, which is critical to ripping out OverloadedFunction.

Also resolves a few FIXMEs.

John McCall a9ee325d71 If a C++ qualified id is followed by a postfix suffix, it is never the direct
operand of an addressof operator, and so we should not treat it as an abstract
member-pointer expression and therefore suppress the implicit member access.

This is really a well-formedness constraint on expressions:  a DeclRefExpr of
a FieldDecl or a non-static CXXMethodDecl (or template thereof, or unresolved
collection thereof) should not be allowed in an arbitrary location in the AST.
Arguably it shouldn't be allowed anywhere and we should have a different expr
node type for this.  But unfortunately we don't have a good way of enforcing
this kind of constraint right now.
