Make Sema pass the LangOptions to IdentifierResolver's constructor.

- Replace string comparisons with pre-defined idents.
- Avoid calling isBuiltinObjCType() to avoid two checks. 
- Remove isBuiltinObjCType(), since it was only used in Sema::MergeTypeDefDecl().
- Have Sema::MergeTypeDefDecl() set the new type.

This is a moidified version of an patch by David Chisnall.

llvm-svn: 55990

Remove "NextDecl" from RecordDecl.  This change touches many files that where RecordDecl or CXXRecordDecl was constructed, always with an argument of 'NULL' for the previous declaration.

The motivation behind this change is that chaining the RecordDecls is simply unnecessary.  Once we create multiple RecordDecls for the same struct/union/class, clients that care about all the declarations of the same struct can build a back map by seeing which Decls refer to the same RecordType.

Highlights...

- 4 new AST nodes, BlockExpr, BlockStmtExpr, BlockExprExpr, BlockDeclRefExpr.
- Sema::ActOnBlockStart(), ActOnBlockError(), ActOnBlockStmtExpr(), ActOnBlockExprExpr(), ActOnBlockReturnStmt().

Next steps...

- hack Sema::ActOnIdentifierExpr() to deal with block decl refs.
- add attribute handler for byref decls.
- add test cases.

Make sure to create CXX record decls for the implicit Obj-C type declarations. This lets us compile Cocoa.h as Objective-C++

 - Added as private members for each because it is not clear where to
   put the common definition. Perhaps the IdentifierInfos all of these
   "pseudo-keywords" should be collected into one place (this would
   KnownFunctionIDs and Objective-C property IDs, for example).

Remove Token::isNamedIdentifier.
 - There isn't a good reason to use strcmp when we have interned
   strings, and there isn't a good reason to encourage clients to do
   so.

 - Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

llvm-svn: 54632

 - Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
 - Moved Sema::getCurMethodDecl() out of line (dependent on
   ObjCMethodDecl via dyn_cast).

llvm-svn: 54629

 - Drop Expr.h,RecordLayout.h from ASTContext.h (for DeclBase.h and
   SourceLocation.h)
 - Move ASTContext constructor into implementation

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>
~~~~~~~~~~~~~~~~~~~~~   ^

instead of:

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

interfaces.  Just because they x->isPointerType() doesn't mean it is
valid to just cast to a pointertype.  We have to handle typedefs etc
as well.

Replace CurFunctionDecl and CurMethodDecl with methods getCurFunctionDecl() and getCurMethodDecl() that return the appropriate Decl through CurContext.

"This moves built-in Objective-C types up the scope chains to where they can be replaced by versions included from the runtime library's headers."

This makes it ok to use @"foo" without a declaration for NSConstantString.

llvm-svn: 52336

  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.

-Added TranslationUnitDecl class to serve as top declaration context
-ASTContext gets a TUDecl member and a getTranslationUnitDecl() function
-All ScopedDecls get the TUDecl as DeclContext when declared at global scope

-Renamed ContextDecl -> DeclContext
-Removed DeclContext pointer from FieldDecl
-EnumDecl inherits from DeclContext, instead of TagDecl

Patch by Argiris Kirtzidis!

llvm-svn: 49261

-Added ContextDecl (no TranslationUnitDecl)
-ScopedDecl class has a ContextDecl member
-FieldDecl class has a ContextDecl member, so that a Field or a ObjCIvar can be traced back to their RecordDecl/ObjCInterfaceDecl easily
-FunctionDecl, ObjCMethodDecl, TagDecl, ObjCInterfaceDecl inherit from ContextDecl. With TagDecl as ContextDecl, enum constants have a EnumDecl as their context.
-Moved Decl class to a "DeclBase.h" along with ContextDecl class
-CurContext is handled by Sema

allocation through ASTContext.

lib dir and move all the libraries into it.  This follows the main
llvm tree, and allows the libraries to be built in parallel.  The
top level now enforces that all the libs are built before Driver,
but we don't care what order the libs are built in.  This speeds
up parallel builds, particularly incremental ones.

all Create methods.

llvm-svn: 48398

Right now only some ctors are switched over.  I need to switch them all
over so I can change the dtor over.

This lets us experiment with region allocation and other things in the 
future.

llvm-svn: 48390

Move the initialization of SEL/objc_selector from Sema::Sema() to Sema::ActOnTranslationUnitScope() and make sure the type/struct get inserted into the translation unit scope.
