Daniel Dunbar afec1f58e9 Driver: Finish porting Darwin::Preprocess and Compile port (still 
unused, and lacking a test case).
 - ccc is now on death row, pending some more testing and bug fixes.

(currently unused).

Chris Lattner 5bbb3c8ad9 Push DeclGroup much farther throughout the compiler. Now the various 
productions (except the already broken ObjC cases like @class X,Y;) in 
the parser that can produce more than one Decl return a DeclGroup instead
of a Decl, etc.

This allows elimination of the Decl::NextDeclarator field, and exposes
various clients that should look at all decls in a group, but which were
only looking at one (such as the dumper, printer, etc).  These have been
fixed.

Still TODO:

1) there are some FIXME's in the code about potentially using
DeclGroup for better location info.
2) ParseObjCAtDirectives should return a DeclGroup due to @class etc.
3) I'm not sure what is going on with StmtIterator.cpp, or if it can
   be radically simplified now.
4) I put a truly horrible hack in ParseTemplate.cpp.

I plan to bring up #3/4 on the mailing list, but don't plan to tackle
#1/2 in the short term.

Chris Lattner 6c84a5a394 DeclRefExpr refers to one decl, not all the declarators in a declaration. 
Ted, please check this, this change causes no regression tests to fail.

necessarily pointers.

Chris Lattner e50f47971b When forming sentinels for empty/tombstone, make sure to respect the 
pointer's expected number of zero low-bits.

This should fix the breakage I introduced recently.

Chris Lattner b81eb052f2 switch DeclBase::DeclCtx to the new happy and type-safe 
llvm::PointerUnion class.

llvm-svn: 67988
 2009-03-29 06:06:59 +00:00
Chris Lattner a9c6de15fb Add a simple type-safe bit-mangling pointer union class. This allows 
you to do things like:

  ///    PointerUnion<int*, float*> P;
  ///    P = (int*)0;
  ///    printf("%d %d", P.is<int*>(), P.is<float*>()); // prints "1 0"
  ///    X = P.get<int*>();     // ok.
  ///    Y = P.get<float*>();   // runtime assertion failure.
  ///    Z = P.get<double*>();  // does not compile.
  ///    P = (float*)0;
  ///    Y = P.get<float*>();   // ok.
  ///    X = P.get<int*>();     // runtime assertion failure.

llvm-svn: 67987
 2009-03-29 06:06:02 +00:00
Chris Lattner 35c0232cb0 Allow a specific PointerIntPair instance to use a specific Pointer trait: 
some pointer instances have properties that not all of a type have.

llvm-svn: 67986
 2009-03-29 06:02:20 +00:00
Chris Lattner d4ff5fce81 Add a PointerLikeTypeTraits specialization for uintptr_t

Chris Lattner 57ce399326 Make the ActionResult optimization work for non-void*'s and switch DeclPtrTy to use it. 
llvm-svn: 67983
 2009-03-29 05:08:48 +00:00
Chris Lattner cd8bb18624 genericize the ActionResult optimization for holding the "ininvalid" bit 
in the low bit position a little bit (haha).

Chris Lattner 20d79aa1c2 adjust to llvm mainline changes. 
llvm-svn: 67980
 2009-03-29 04:32:54 +00:00
Chris Lattner 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.

llvm-svn: 67979
 2009-03-29 04:32:37 +00:00
Chris Lattner 114597d69b tighten this up, the decl *must* be a declcontext, no need for the dynamic check.

Chris Lattner 22d059dbde follow llvm mainline, where PointerLikeTypeInfo got renamed 
to PointerLikeTypeTraits.

llvm-svn: 67974
 2009-03-29 00:39:47 +00:00
Chris Lattner a00f0d7e4c rename PointerLikeTypeInto to PointerLikeTypeTraits, add trait for 
# low bits free, and move to its own header.

Chris Lattner 8eda11bd9d now that you can put a PointerIntPair in a SmallPtrSet, remove some 
hackish workarounds from memdep

Eli Friedman 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.

llvm-svn: 67969
 2009-03-29 00:15:25 +00:00
Chris Lattner a59a3e2d10 QualType can go in SmallPtrSet now, simplify code that used to have 
to work around this.
