__unknown_anytype, and rewrite such message sends correctly.
I had to bite the bullet and actually add a debugger support mode for this
one, which is a bit unfortunate, but there really isn't anything else
I could imagine doing; this is clearly just debugger-specific behavior.

the complete destructor and then invoke the global delete
operator. Previously, we would invoke the deleting destructor, which
calls the wrong delete operator. Fixes PR10341.

block pointers) that don't have any qualification to be POD types. We
were previously considering them to be non-POD types, because this was
convenient in C++ for is_pod-like traits. However, we now end up
inferring lifetime in such cases (template arguments infer __strong),
so it is not necessary.
Moreover, we want rvalues of object type (which have their lifetime
stripped) to be PODs to allow, e.g., va_arg(arglist, id) to function
properly. Fixes <rdar://problem/9758798>.

dependent. This covers an odd class of types such as
int (&)[sizeof(sizeof(T() + T()))];
which involve template parameters but, because of some trick typically
involving a form of expression that is never type-dependent, resolve
down to a non-dependent type. Such types need to be mangled
essentially as they were written in the source code (involving
template parameters), rather than via their canonical type.
In general, instantiation-dependent types should be mangled as
they were written in the source. However, since we can't do that now
without non-trivial refactoring of the AST (see the new FIXME), I've
gone for this partial solution: only use the as-written-in-the-source
mangling for these strange types that are instantiation-dependent but
not dependent. This provides better compatibility with previous
incarnations of Clang and with GCC. In the future, we'd like to get
this right.
Fixes <rdar://problem/9663282>.

builds introduced in r134972:
lib/CodeGen/CGExpr.cpp:1294:7: error: no matching function for call to 'EmitBitCastOfLValueToProperType'
lib/CodeGen/CGExpr.cpp:1278:1: note: candidate function not viable: no known conversion from 'CGBuilderTy' (aka 'IRBuilder<false>') to 'llvm::IRBuilder<> &' for 1st argument
This fixes the issue by passing CodeGenFunction on down, and using its
builder directly rather than passing just the builder down.
This may not be the best / cleanest fix, Chris please review. It at
least fixes builds.

isSugared() and desugar() routines previously provided were never
actually called, since the corresponding types
(DependentTypeOfExprType, DependentDecltypeType) don't have
corresponding type classes. Outside of the current (incomplete) patch
I'm working on, I haven't found a way to trigger this problem.

uncompleted struct types. We now do what llvm-gcc does and compile
them into [i8 x 0]. If the type is later completed, we make sure that
it is appropriately cast.
We compile the terrible example to something like this now:
%struct.A = type { i32, i32, i32 }
@g = external global [0 x i8]
define void @_Z1fv() nounwind {
entry:
call void @_Z3fooP1A(%struct.A* bitcast ([0 x i8]* @g to %struct.A*))
ret void
}
declare void @_Z3fooP1A(%struct.A*)
define %struct.A* @_Z2f2v() nounwind {
entry:
ret %struct.A* getelementptr inbounds ([0 x %struct.A]* bitcast ([0 x i8]* @g to [0 x %struct.A]*), i32 0, i64 1)
}
llvm-svn: 134972
stuff like this:
typedef struct {
int x, y, z;
} foo_t;
foo_t g;
into:
%"struct.<anonymous>" = type { i32, i32, i32 }
we now get:
%struct.foo_t = type { i32, i32, i32 }
This doesn't change the behavior of the compiler, but makes the IR much easier to read.
