isn't guaranteed to exist. This fixes a crash with conflicting typedefs
coming from stdin.

This also fixes the crash in PR2406, but doesn't completely fix the 
issue; it appears there's something strange about the physical location 
for the definition of int64_t in stdlib.h.

-ScopedDecls get chained to their DeclContext.
-DeclContext's DeclChain replaces FunctionDecl's DeclChain and EnumDecl's ElementList.

llvm-svn: 52164

  Added TagKind enum.
  Added getTagKind() method.
  Added convenience methods: isEnum(), isStruct(), isUnion(), isClass().
-RecordDecl/CXXRecordDecl::Create() accept a TagKind enum instead of a DeclKind one.

pointer cast hack currently in isIntegerConstantExpr 
(in lib/AST/Expr.cpp).  Also removes an odd test that even gcc doesn't accept.

The reason the pointer cast hack is relevant here is that it makes Sema 
end up misinterpreting the relevant expression as a null pointer constant.

The reason for this patch is that I plan to remove the pointer cast hack 
sometime soon because it causes strange issues, especially in its 
current form; see my recent email to cfe-dev
"[PATCH] add constant expression evaluation to the AST and fix PR2413".

type; this isn't explicitly stated in the standard, but it doesn't 
really make sense for them to have an effect here.  Fixes the included 
testcase, sent to me by Steve Naroff.

Second half of "fix" for <rdar://problem/5986085> clang on xcode: error: redefinition of 'XCElementToggler' as different kind of symbol

- Changed Sema::ObjCActOnStartOfMethodDef() to more accurately type "self" in factory methods.
- Changed Sema::ActOnInstanceMessage() to use the new type to restrict the lookup.

llvm-svn: 52005

In addition to fixing the crasher, this commit fixes further improves property lookup (by searching protocols of qualified interfaces..."NSObject <prot>").

Please confirm this is safe

assigned to less protocol qualified object on LHS.

llvm-svn: 51956

Moved LangOptions from TranslationUnit to ASTContext.  This induced a variety of cleanups in some ASTConsumers.

llvm-svn: 51943

Sema::ActOnClassMessage() needs to look through it's local implementation for private class methods.

Fix <rdar://problem/5967199> clang on xcode: error: member reference is not to a structure or union

llvm-svn: 51919

moves the check for the invalid construct to a point where it doesn't 
affect other uses of isIntegerConstantExpr, and we can warn properly 
when the extension is used.  This makes it a bit more complicated, but 
it's a lot cleaner.

Steve, please tell me if this check is sufficient to handle the 
relevant system header.  I know it's enough to handle the testcase, but 
I don't know what exactly the original looks like.

llvm-svn: 51913

Allow implicit pointer/int conversions on ObjCQualifiedIdTypes in Sema::CheckCompareOperands() and Sema::CheckAssignmentConstraints().

Fixes <rdar://problem/5980804> clang on xcode: error: incompatible type sending 'id<XDUMLType>', expected 'NSCellType'.

Fixes part of <rdar://problem/5980829> clang on xcode: used type 'NSRange' where arithmetic or pointer type is required.

this plugs the leak of attributes and also fixes a crash in the test

llvm-svn: 51862

This eliminates a bogus warning identified in the test below.

This fixes <rdar://problem/5968256> clang on xcode: error: incompatible type initializing 'NSObject<XCSelectionSource> *', expected 'id<NSObject,XCSelectionSource>'

llvm-svn: 51832

Teach Sema::CheckConditionalOperands() to check for ObjCQualifiedIdType's. This fixes a bogus error.

<rdar://problem/5967036> clang on xcode: error: incompatible operand types ('id<DTOutputStreams>' and 'DTFilterOutputStream *')

TranslationUnit object instead of an ASTContext. By default it calls
Initialize(ASTConstext& Context) (to match with the current interface used by
most ASTConsumers).

Modified the ObjC-Rewriter to use InitializeTU, and to tell the TranslationUnit
to not free its Decls.  This is a workaround for: <rdar://problem/5966749>

llvm-svn: 51825

llvm-svn: 51809

required by the standard (the standard doesn't know anything about 
implicit casts).

Disallow pointers cast to non-integral arithmetic types as constant 
expressions.  This was previously allowed by accident.

llvm-svn: 51778

While it is far from complete, it does fix the following <rdar://problem/5967199> clang on xcode: error: member reference is not to a structure or union
