Ted Kremenek a8b8ce499a Add range highlighting for path-sensitive return-of-stack-address check. 
llvm-svn: 54219
 2008-07-30 17:49:12 +00:00
Daniel Dunbar e49df9b58f Change CodeGenModule GlobalDeclMap to directly reference globals 
instead of mapping the decl to a bitcast of the global to the correct
type.
 
 - GetAddrOf{Function,GlobalVar} introduce the bitcast on every use now.

 - This solves a problem where a dangling pointer could be introduced
   by the RAUW done when replacing a forward or tentative
   definition. See testcase for more details.

 - Fixes <rdar://problem/6108358>

Daniel Dunbar 9c426524f8 Rework codegen emission of globals 
- No (intended) functionality change.

 - Primary purpose is to clearly separate (lazy) construction of
   globals that are a forward declaration or tentative definition from
   those that are the final definition.

 - Lazy construction is now encapsulated in
   GetAddrOf{Function,GlobalVar} while final definitions are
   constructed in EmitGlobal{Function,Var}Definition.
 
 - External interface for dealing with globals is now limited to
   EmitGlobal and GetAddrOf{Function,GlobalVar}.

 - Also updated helper functions dealing with statics, annotations,
   and ctors to be private.

Chris Lattner a075e63bbc fix several problems with the protocol qualified id handling where id was implicit. 
First, fix canonical type handling of these, since protocol qualified id's are always
canonical.  Next, enhance SemaType to actually make these when used (instead of int)
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

changes the testcase to be substantially reduced.

Ted Kremenek 04350ebe4a Refine ObjCPropertyImplDecl: 
- Remove a bunch of setXXX methods until we actually need them. This cleans up the
interface, and makes the object immutable until we have a reason to be mutable.

- Remove enum value OBJC_PR_IMPL_None since it was never used.

- Remove instance variable 'PropertyImplKind PropertyImplementation;'. This is
  not needed because we can tell if ObjCPropertyImplDecl represents @synthesize
  if 'ObjCPropertyDecl *PropertyDecl' is not null.

Steve Naroff 6c79f97037 Fix Sema::ActOnClassMessage() to pass through the identifier for "super". 
This fixes a critical rewriter bug (<rdar://problem/6096760> clang ObjC rewriter: 'self' not expected value in class method called with 'super').

Also added a couple FIXME's since I'm not happy with my fix to Sema. It would be nicer if the super handling for class/instance messages was the same (based on PreDefinedExpr).

Chris Lattner ca1e848588 Switch initialization of the protocol list for an interface decl to use 
the standard "set these as the list of protocols" interface instead of a 
strange "set this as the size and then set each one to the value" interface.
The problem with the later is that it a) is completely different from 
everything else, b) is awkward, and c) doesn't handle the case when a
referenced protocol is invalid: it set it to null.

This meant that all clients downstream would have to handle null protocols
in the protocol list, and empirically they didn't.  Fix this by not setting
invalid protocols in the referenced protocol list, fixing the crash on 
test/Sema/objc-interface-1.m

While I'm at it, clean up some locations so that we produce:

t.m:1:25: error: cannot find interface declaration for 'NSObject', superclass of 'NSWhatever'
@interface NSWhatever : NSObject <NSCopying>
~~~~~~~~~~~~~~~~~~~~~   ^
