ok class names and streamlined this logic to do the lookup once.

llvm-svn: 42926

Replace one FIXME with another. We handle protocols just fine now. The ObjC decl will only be 0 when we have an error on the ObjC decl. I would prefer we pass in a decl that is marked as invalid. I don't think this is critical to fix now, however I'd like us to be consistent. There are currently many places that don't mark the decl as invalid (which need to be fixed)...

Add __builtin_va_start to the list of builtins, make __builtin_va_list available to builtin functions.

- Cache the typedef, not the type (avoids importing AST/Type.h).
- Emit an error if "id" cannot be found.
- Comment the routine and add a FIXME to reconsider how we emulate GCC's new fangled behavior. This isn't a priority for now, since almost no code depends on having "id" built-in.
- Add a test.

llvm-svn: 42845

- Make sure default return/argument types (for methods) default to "id".
- Cache the "id" type in Sema...initialize ObjcIdType and TUScope (oops).
- Fix ActOnInstanceMessage to allow for "id" type receivers...still work to do (next).

llvm-svn: 42840

Remove Scope argument from ObjC actions that either don't need it or can now use TUScope.
Also improve a recently added comment.

predefined macros.  Previously, these were handled by the driver,
now they are handled by the preprocessor.

Some fallout of this:

1. Instead of preprocessing two buffers (the predefines, then the 
   main source file)  we now start preprocessing the main source 
   file and inject the predefines as a "psuedo #include" from the
   main source file.
2. #1 allows us to nuke the Lexer::IsMainFile flag and simplify
   Preprocessor::isInPrimaryFile.
3. The driver doesn't have to know about standard #defines, the
   preprocessor knows, which is nice for people wanting to define
   their own drivers.
4. This allows us to put normal tokens in the predefine buffer,
   for example a definition for __builtin_va_list that is 
   target-specific, and a typedef for id in objc.

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.

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

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.
