Douglas Gregor 043cad21b7 Diagnose VLAs as an error in C++. 
Also, treat the GNU __null as an integral constant expression to match
GCC's behavior.

Douglas Gregor 9cd9f3f55d For a C++ delete expression where the operand is of class type that 
has a single conversion to pointer-to-object type, implicitly convert
to that pointer-to-object type (C++ [expr.delete]p1).

Douglas Gregor 39da0b8145 Improve handling of initialization by constructor, by ensuring that 
such initializations properly convert constructor arguments and fill
in default arguments where necessary. This also makes the ownership
model more clear.

Douglas Gregor a78c5c34fb If a destructor is referenced or a pseudo-destructor expression is 
formed without a trailing '(', diagnose the error (these expressions
must be immediately called), emit a fix-it hint, and fix the code.

Douglas Gregor a71d819bb8 Implement AST, semantics, and CodeGen for C++ pseudo-destructor 
expressions, e.g.,

  p->~T()

when p is a pointer to a scalar type. 

We don't currently diagnose errors when pseudo-destructor expressions
are used in any way other than by forming a call.

Douglas Gregor c68afe2cbe Improve template instantiation for member access expressions that 
involve qualified names, e.g., x->Base::f. We now maintain enough
information in the AST to compare the results of the name lookup of
"Base" in the scope of the postfix-expression (determined at template
definition time) and in the type of the object expression.


git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@80953 91177308-0d34-0410-b5e6-96231b3b80d8
 2009-09-03 21:38:09 +00:00
Douglas Gregor 2dd078ae50 Rewrite of our handling of name lookup in C++ member access expressions, e.g., 
x->Base::f

We no longer try to "enter" the context of the type that "x" points
to. Instead, we drag that object type through the parser and pass it
into the Sema routines that need to know how to perform lookup within
member access expressions.

We now implement most of the crazy name lookup rules in C++
[basic.lookup.classref] for non-templated code, including performing
lookup both in the context of the type referred to by the member
access and in the scope of the member access itself and then detecting
ambiguities when the two lookups collide (p1 and p4; p3 and p7 are
still TODO). This change also corrects our handling of name lookup
within template arguments of template-ids inside the
nested-name-specifier (p6; we used to look into the scope of the
object expression for them) and fixes PR4703.

I have disabled some tests that involve member access expressions
where the object expression has dependent type, because we don't yet
have the ability to describe dependent nested-name-specifiers starting
with an identifier.

DeclaratorDecl contains a DeclaratorInfo* to keep type source info.

EnumConstantDecl still inherits from ValueDecl since it has no need for DeclaratorInfo.

Decl/Sema interfaces accept a DeclaratorInfo as parameter but no DeclaratorInfo is created yet.
