Daniel Dunbar ce05c8eb49 Fix two bugs exposed by array passing assert:
(1) Additional arguments to variadic methods should have default
promotions applied.

Daniel Dunbar 0beedc1684 Fix a number of issues w.r.t. emission of global for functions and
aliases.
 - Attributes specific to a definition are only set when the
   definition is seen.
 - Alias generation is delayed until the end of the module; necessary
   since the alias may reference forward.
 - Fixes: PR2743, <rdr://6140807&6094512>
 - Improves: <rdr://6095112> (added XFAIL)

Also, print module on verification failures.

Eli Friedman 7c9ba6a1e3 An extremely hacky version of transparent_union support; it isn't

Daniel Dunbar 40bf7fe20e In incompatible pointer-typed ?: expressions, add implicit conversion
of RHSs to id type instead of void* if either has Objective-C object
type.
 - This ensures the result can still be used in normal places an
   object can be used, like a message send.

Add implicit conversions for ?: applied to qualified id types to
ensure that the RHSs are compatible. 
 - This prevents a codegen crash (creating invalid PHI nodes).
 - Again, this relates to the fact that qualified id types have no
   canonical types.
 - Note that the implicit type casted to is incorrect, however this
   doesn't currently cause problems because of the flexibility of the
   id type.

Test cases for above.

Eli Friedman 0a2ba3f10b Fix for PR2720; be a little bit more permissive in initializers for

Steve Naroff 239255d2a6 Fix Sema::MergeVarDecl() to better handle type compatibility. The previous code was trying to handle arrays specially (which didn't work for pointers to array). Removed local helper function areEquivalentArrayTypes(), replacing it's use with the more general ASTContext::typesAreCompatible() predicate.
Even though the test case this fixes is in "tentative-decls.c", this bug didn't have anything to do with our handling of tentative definitions (which is what I first expected). In any event, this is a tricky area of the spec.

Steve Naroff 5bb8f2264b Fix issues with C "tentative" definitions.
- Move checking from MergeVarDecl->FinializeDeclaratorGroup. Since MergeVarDecl is called before the initializer is attacted, it can't be done there (this removes a long standing FIXME).
- Add Sema::isTentativeDefinition() and Sema::CheckForFileScopedRedefinitions().
- Remove FIXME's and touch-up test case.

Still some more work to do (forthcoming)...

Daniel Dunbar ead7c91240 Fix bitfield accesses which straddle the boundary of the underlying
type.

 - This generates somewhat less optimal code than before but this is
   not hard to rectify once stable (at the cost of slightly more
   complex code).

 - This currently always uses little-endian ordering of the bitfield. 

 - This breaks the CodeGen/bitfield.c test because it was grepping for
   hard-coded assembly instructions. Will fix once a better test case
   is constructed (hard to do without execution).

 - This fixes SingleSource/UnitTests/2006-01-23-InitializedBitField.c
   and Regression/C/PR1386.c from the test suite.

Daniel Dunbar bfb1cd7454 Fix CodeGen of pointer arithmetic in compound assignment statements.
- Changed EmitSub to work on all cases (arithmetic, ptr - int, ptr -
   ptr) so that implementation matches that of other operators.

 - Modify EmitCompoundAssign to compute and perform the appropriate
   casts of left, right, and result types for the assorted pointer
   arithmetic cases.

 - Fix EmitSub (ptr - int) case to negate the rhs *after*
   extension. This is critical when the rhs is unsigned (and needs
   extension).

 - This fixes cfrac.

Daniel Dunbar ffc29be83f Implement GNU asm-label extension support in CodeGen. This fixes
scimark2 on Darwin.

 - Added Sema support for asm-label on variables, which I forgot before.

 - Update CodeGen to use GlobalDeclMap to determine if static Decls
   require emission (instead of LLVM module name lookup). Important
   since the Decl name and the LLVM module name can differ.

Daniel Dunbar 829e988899 Change CodeGen of global decls to key off of the name (instead of
having multiple bindings from all the possible decls which
  conceptually map to the same global).

 - This eliminates CodeGen depending on the LLVM module for name
   lookup.

 - This also eliminates the need for ReplaceMapValuesWith (hurrah).

 - This handles lookups for FunctionDecls correctly in the presence of
   aliases, this was previously broken.

 - WIP: Can still clean up & unify variable and function emission.

Daniel Dunbar 88402ce8d0 Add CodeGen support for indirect goto.
- Follows emission scheme used by llvm-gcc, i.e. invent an id for
   each label whose address is taken and replace each indirect goto by
   a switch to each possible target.
 - Currently we emit a switch for each indirect goto instead of
   merging them as llvm-gcc does.

Chris Lattner 7adf076088 Finally fix PR2189. This makes a fairly invasive but important change to
move getAsArrayType into ASTContext instead of being a method on type.
This is required because getAsArrayType(const AT), where AT is a typedef
for "int[10]" needs to return ArrayType(const int, 10).

Fixing this greatly simplifies getArrayDecayedType, which is a good sign.

First, fix canonical type handling of these, since protocol qualified id's are always

allowing them to actually be used when appropriate.  Finally remove a bunch of logic
relating to the mishandling of canonical types with protocol-qual id's.  This fixes
