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.

  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.

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.

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.

Sema::ActOnTranslationUnitScope.  The various ObjC pieces at the top
of Sema.cpp should be moved into SemaObjC or something.

a method named ImpCastExprToType in Sema.

Use this method to insert implicit casts for case statements from their 
operand type to the condition type of the switch.  This fixes a crash on
test/CodeGen/statements.c, reported by Eli Friedman.

Moved all clients of Diagnostics to use FullSourceLoc instead of SourceLocation.
Added many utility methods to FullSourceLoc to provide shorthand for:

    FullLoc.getManager().someMethod(FullLoc.getLocation());
    
instead we have:

    FullLoc.someMethod();
    
Modified TextDiagnostics (and related classes) to use this short-hand.

llvm-svn: 44957

SourceManager is passed by reference, allowing the SourceManager to be
associated with a specific translation unit, and not the entire execution
of the driver.

Modified all users of Diagnostics to comply with this new interface.

Integrated SourceManager as a member variable of TargetInfo. TargetInfo will
eventually be associated with a single translation unit (just like
SourceManager).

Made the SourceManager reference in ASTContext private. Provided accessor
getSourceManager() for clients to use instead. Modified clients to comply with
new interface.

Yesterday, I simplified how we stream top-level decls.

After a discussion with Ted, we both came to the conclusion that adding a "HandleTopLevelDeclaration" hook to ASConsumer is far more elegant. The default implementation of HandleTopLevelDeclaration will be responsible for iterating over the ScopedDecl (which has a chain of the decls:-).

TODO: Once Ted adds HandleTopLevelDeclaration, make sure TagDecls are chainged appropriately...
llvm-svn: 44445

Several fixes/simplifications surrounding how we stream top-level decl AST's.

The following code...

typedef struct cssm_data {} CSSM_DATA, *CSSM_DATA_PTR;

struct Y { int A; };

struct X { int A; } D; 

struct X E, F;

...now produces the following output...

> ../../Debug/bin/clang xx.c -ast-print
Read top-level tag decl: 'cssm_data'
typedef struct cssm_data CSSM_DATA;
typedef struct cssm_data *CSSM_DATA_PTR;
Read top-level tag decl: 'Y'
Read top-level tag decl: 'X'
Read top-level variable decl: 'D'
Read top-level variable decl: 'E'
Read top-level variable decl: 'F'

...which is much more accurate than the previous -ast-print output...

typedef struct cssm_data CSSM_DATA;
typedef struct cssm_data CSSM_DATA;
Read top-level variable decl: 'D'
Read top-level variable decl: 'E'
Read top-level variable decl: 'E'

Implement a more sensible strategy for ObjC built-in types (addressing a long standing FIXME in Sema::GetObjcIdType()).

This removes several gross hacks to work around the previous "lazy" behavior.

Two notes:
- MinimalActions still needs to be taught about the built-in types (This breaks one of the -noop test cases). I started this, then added a FIXME.
- I didn't convert Sema::GetObjcProtoType() yet.
