Anders Carlsson ea7b18298e Split adding the primary virtual base offsets out into a separate pass. This fixes a bug where we would lay out virtual bases in the wrong order.

Daniel Dunbar 1da6511b99 Tweak spelling (Bitfield -> BitField)
llvm-svn: 101369
2010-04-15 15:06:18 +00:00
Daniel Dunbar 3d9289c736 Add TargetInfo::useBitfieldTypeAlignment().
- Used to determine whether the alignment of the type in a bit-field is
   respected when laying out structures. The default is true, targets can
   override this as needed.

 - This is designed to correspond to the PCC_BITFIELD_TYPE_MATTERS macro in
   gcc. The AST/Sema implementation only affects one line, unless I have
   forgotten something. I'd appreciate further review.

 - IRgen still needs to be updated to fully support this (which is effectively
   PR5591).

This allows them to be allocated using a BumpPtrAllocated
in the common case.

Mike Stump 0a2754ed8a Be sure to select primary bases among the nearly empties in preorder,
not just among the direct bases.  Before we where missing nearly
empties that were bases of virtual base classes.

Douglas Gregor a318efd1f2 Improve key-function computation for templates. In particular:
- All classes can have a key function; templates don't change that.
  non-template classes when computing the key function.
  - We always mark all of the virtual member functions of class
  template instantiations. 
  - The vtable for an instantiation of a class template has weak
  linkage. 

We could probably use available_externally linkage for vtables of
classes instantiated by explicit instantiation declarations (extern
templates), but GCC doesn't do this and I'm not 100% that the ABI
permits it.

Anders Carlsson f98849eb8a In Sema, whenever we think that a function is going to cause a vtable to be generated, we mark any virtual implicit member functions as referenced.

Alexis Hunt 96d5c76498 Added rudimentary C++0x attribute support.
The following attributes are currently supported in C++0x attribute
lists (and in GNU ones as well):
 - align() - semantics believed to be conformant to n3000, except for
   redeclarations and what entities it may apply to
 - final - semantics believed to be conformant to CWG issue 817's proposed
   wording, except for redeclarations
 - noreturn - semantics believed to be conformant to n3000, except for
   redeclarations
 - carries_dependency - currently ignored (this is an optimization hint)
