DefineImplicitCopyConstructor now uses SetBaseOrMemberInitializers to create implicit base initializers. (Member initializers are still handled by CodeGenFunction::SynthesizeCXXCopyConstructor for now).

Add a new GetAddressOfBaseClass overload that takes a base path and. Use it for derived-to-base casts.

Fix a bug which triggered the assertion I added yesterday. Basically, when we initialize the vtable pointer for a virtual base, and there was another path from the most derived class to another base with the same class type, we would use the wrong base.

Assert that the path from the derived to the base class in CodeGenFunction::GetAddressOfBaseClass is not ambiguous.

function declaration, since it may end up being changed (e.g.,
"extern" can become "static" if a prior declaration was static). Patch
by Enea Zaffanella and Paolo Bolzoni.

llvm-svn: 101826

Have the CXXBaseOrMemberInitializer keep track of whether an initializer initializes a virtual base or not.

This introduces FunctionType::ExtInfo to hold the calling convention and the
noreturn attribute. The next patch will extend it to include the regparm
attribute and fix the bug.

Use the new function in EmitClassAggrMemberwiseCopy, fixing the same assert as seen in PR6628 but for arrays this time.

Handle default arguments when calling copy constructors for bases or members when synthesizing a copy constructor. Fixes PR6628.

Flip the switch to always get vtables from the VTT when necessary, I've verified that clang bootstraps with this.

Use construction vtables when needed. This is currently guarded by -fdump-vtable-layouts since it doesn't work 100% yet :)

llvm-svn: 99787

Reapply r99775 with a fix for a silly bug - we were setting the vtable pointer for all bases, even those without a vtable pointer :)

llvm-svn: 99777

llvm-svn: 99776

More improvements to setting the vtable pointer. We now no longer set the vtable pointer for non-virtual primary bases. We also do a pre-order traversal of the class hierarchy; this is necessary in order to get the right vbase offset offsets in base ctors/dtors.

1) emit base destructors as aliases to their unique base class destructors
under some careful conditions.  This is enabled for the same targets that can
support complete-to-base aliases, i.e. not darwin.

2) Emit non-variadic complete constructors for classes with no virtual bases
as calls to the base constructor.  This is enabled on all targets and in
theory can trigger in situations that the alias optimization can't (mostly
involving virtual bases, mostly not yet supported).

These are bundled together because I didn't think it worthwhile to split them,
not because they really need to be.

Fix some bugs with function-try-blocks and simplify normal try-block
code generation.

This implementation excludes a deleting destructor's call to
operator delete() from the function-try-block, which I believe
is correct but which I can't find straightforward support for at
a moment's glance.
