Make sure methods with no return type default to "id".

This fixes a crasher in Sema::MatchTwoMethodDeclarations(), identified by selector-overload.m (just added).

Added Action::ActOnTranslationUnitScope() and renamed Action::PopScope to ActOnPopScope.

Added a Translation Unit Scope instance variable to Sema (will be very useful to ObjC-related actions, since ObjC declarations are always file-scoped).

DenseMap to keep track of such declarations and derive ObjcProtocolDecl
directyly from NamedScope.

llvm-svn: 42801

ParseFunctionDefinition so that ActOnFunctionDefBody is always
called if ActOnStartOfFunctionDef is called.  This fixes a crash
reported by Nuno Lopes.

llvm-svn: 42793

fatal error of category's undefined interface.

llvm-svn: 42790

Convert Selector Maps/Sets to use stronger typing (now that we have DenseMapInfo in IdentifierTable.h).

NamedDecl is a Decl that has an IdentifierInfo (for example, ScopedDecl), 
but not ObjcMethodDecl.

Simplify some code in ActOnAddMethodsToObjcDecl, by doing the cast from 
DeclTy to Decl at the start of the method.

objective-c types. It also removes use of Scope* parameter in
getObjCProtocolDecl.

llvm-svn: 42649

Selector's instead of requiring void* to be used.  I converted one use of
DenseSet<void*> over to use DenseSet<Selector> but the others should change
as well.

llvm-svn: 42645

2) Use of the new DenseSet<t> abstractions instead of DenseMap<t,char>.

fixed consequence of these changes in clang.

llvm-svn: 42600

Finish renaming ObjC declaration actions.
Add comments.
Switch to new indentation style for the Action class. Since many actions take many arguments, the new style will...
- make it easier to add/remove arguments without messing up the indentation...
- make it easier to add comments to each argument (see ActOnMethodDeclaration for an example)...
- in general, just makes it easier to see what is being passed.

The rest of Actions will be converted "lazily"...there is no immediate need to hack all the existing methods.

llvm-svn: 42587

getter names.

llvm-svn: 42577

Rename several ObjC action methods to use the "ActOn" prefix (still a few more to do).
Remove Action::ObjCStartCategoryInterface/ObjCFinishInterface - they are unused.
.

llvm-svn: 42559

and their accessors in a variety of objective-c classes.

llvm-svn: 42555

Remove Action::ActOnImpleIvarVsClassIvars(), it is only called by Sema (not Parser).
Add Sema::CheckImplementationIvars() to replace the previous action.

llvm-svn: 42553

Rename ObjcInterfaceDecl::getIsForwardDecl() to isForwardDecl().
Rename ObjcProtocolDecl::getIsForwardProtoDecl() to isForwardDecl().
Rename ObjcInterfaceDecl::setIsForwardDecl() to setForwardDecl().
Rename ObjcProtocolDecl::setIsForwardProtoDecl() to setForwardDecl().

Two reasons:

#1: boolean predicates should start with "is".
#2: Since these two sets of methods represent the same concept, they should be named the same (polymorphism is good:-)

llvm-svn: 42545

Now, I also warn those class/categories which are incomplete because of this.

llvm-svn: 42544

- Add ObjcInterfaceDecl::lookupInstanceMethod(), lookupClassMethod().
- Add ObjcMessageExpr::getSelector(), getClassName().
- Change Sema::getObjCInterfaceDecl() to simply take an IdentifierInfo (no Scope needed).
- Remove FIXME for printing ObjCMessageExpr's.

llvm-svn: 42543

Ted may want to take a look at the change I made at 
FGRecStmtDeclVisitor.h.

llvm-svn: 42535

unimplemented methods in category implementation.

llvm-svn: 42531

Move ObjC decls to DeclObjC.h, a new AST header.
Update clients and add to project file.

Avoiding passing a Sema object to these utility functions.

llvm-svn: 42472

previous patch to do the same for class name lookup using a hash table.

llvm-svn: 42471

There is still an issue if doing ScopedLookup is an overkill and we can
just access the decl using the identifier.
