 - Encode unions and bit-fields correctly.
 - Accept option to name record fields (used for NeXT runtime).

 - Mechanism for detecting if a structure should be expanded wasn't
   reliable. Simplified by just keeping track of what we should be
   expanding.

 - This fixes a bug in using NSInvocation to invoke a method which
   returned a structure, which in used by Key Value Observing, which
   in the end, caused a miscompile in poor little Sketch.

 - With testcase, which also has some other things GCC folds but we
   don't commented out in it.

is to encode the state of the #pragma pack stack as an attribute when
the structure is declared. 

 - Extend PackedAttr to take an alignment (in bits), and reuse for
   both __attribute__((packed)) (which takes no argument, instead
   packing tightly (to "minimize the memory required") and for #pragma
   pack (which allows specification of the maximum alignment in
   bytes). __attribute__((packed)) is just encoded as Alignment=1.

   This conflates two related but different mechanisms, but it didn't
   seem worth another attribute.

 - I have attempted to follow the MSVC semantics as opposed to the gcc
   ones, since if I understand correctly #pragma pack originated with
   MSVC. The semantics are generally equivalent except when the stack
   is altered during the definition of a structure; its not clear if
   anyone does this in practice. See testcase if curious.

Also added serialization support to OverloadExpr.

Instead of using two sets of Decl kinds (Struct/Union/Class and CXXStruct/CXXUnion/CXXClass), use one 'Record' and one 'CXXRecord' Decl kind and make tag kind a property of TagDecl.
Cleans up the code a bit and better reflects that Decl class structure.

on non-float types.

No functionality change.

llvm-svn: 57417

When the static type on the Decl side is a subclass of DeclContext the compiler will use a "inlinable" static_cast, instead of always using an out-of-line function call.

Note, though, that the isa<> check still uses an out-of-line function call.

Final phase of converting BlockDecls over to DeclContext. This is unfortunately a largish/complex diff, however it was necessry to pass all the current block tests.

llvm-svn: 57337

llvm-svn: 57332

This required changes to attach the compound statement later on (like we do for functions).

llvm-svn: 57304

- Modify BlockExpr to reference the BlockDecl.

This is "cleanup" necessary to improve our lookup semantics for blocks (to fix <rdar://problem/6272905> clang block rewriter: parameter to function not imported into block?).

Still some follow-up work to finish this (forthcoming).

llvm-svn: 57298

A little more tweaking with StmtIterator and SizeOfAlignofExpr.  A recent commit actually introduced a regression, not fixed a bug.

llvm-svn: 57282

This also removes the ugly hack needed in CFG.cpp for subclassing DeclStmt to create a DeclStmt with one Decl*.

llvm-svn: 57275

Fixed a masked bug when iterating over the child expressions of SizeOfAlignOfTypeExpr.  This bug was unmasked by recent changes to StmtIterator.

llvm-svn: 57273

Serialization for OwningDeclGroupRefs now works.

llvm-svn: 57272

llvm-svn: 57271

llvm-svn: 57222

Modified DeclGroupRef to always load/store the internal pointer value as Decl*.  This hopefully will obviate any concerns with violating strict type-aliasing issues.

This patch precedes removing getDecl() DeclStmt::entirely.

llvm-svn: 57205

llvm-svn: 57204

Added PrintRawDeclStmt; use this method to print out DeclStmt instead of using PrintRawDecl (which falsely assumes DeclStmts have only one Decl).
