eb71b17705 Replace the PointerLikeTypeTraits::getNumLowBitsAvailable 
function with a new NumLowBitsAvailable enum, which makes the
value available as an integer constant expression.

Add PointerLikeTypeTraits specializations for Instruction* and
Use** since they are only guaranteed 4-byte aligned.

Enhance PointerIntPair to know about (and enforce) the alignment
specified by PointerLikeTypeTraits.  This should allow things 
like PointerIntPair<PointerIntPair<void*, 1,bool>, 1, bool> 
because the inner one knows that 2 low bits are free.

bbcf49e410 Initial implementation of ARM ABI. Mostly untested. Note that I'm not 
really intending to take ownership of this; I wrote this mostly because 
I was curious about how the ARM ABI works.  It should be a decent start, 
though.

356d974a93 add a note 
llvm-svn: 67953
 2009-03-28 19:26:55 +00:00
Chris Lattner
83f095cc7e Introduce a new OpaquePtr<N> struct type, which is a simple POD wrapper for a 
pointer.  Its purpose in life is to be a glorified void*, but which does not
implicitly convert to void* or other OpaquePtr's with a different UID.

Introduce Action::DeclPtrTy which is a typedef for OpaquePtr<0>.  Change the 
entire parser/sema interface to use DeclPtrTy instead of DeclTy*.  This
makes the C++ compiler enforce that these aren't convertible to other opaque
types.

We should also convert ExprTy, StmtTy, TypeTy, AttrTy, BaseTy, etc,
but I don't plan to do that in the short term.

The one outstanding known problem with this patch is that we lose the 
bitmangling optimization where ActionResult<DeclPtrTy> doesn't know how to
bitmangle the success bit into the low bit of DeclPtrTy.  I will rectify
this with a subsequent patch.
