Several fixes to SemaInit.cpp. It's still not enabled (since it fails a few tests). Expect to enable it very soon.

protocols into class's property list and performing semantics

llvm-svn: 50587

Replace Sema::CheckInitializerListTypes() with a helper class (InitListChecker) that synthesizes implicit InitListExpr's when appropriate (see InitListExpr comments in Expr.h for more details). I also moved the code to SemaInit.cpp, to help reduce clutter in SemaDecl.cpp.

NOTE: This work is incomplete and still fails many tests (as a result, it isn't enabled yet). Nevertheless, I wanted to check it in so I can work on it from home.

inheritance in C++. It'll parse the base-specifier list, e.g.,

 class D : public B1, virtual public B2 { };

and do some of the simpler semantic checks (B1 and B2 are classes;
they aren't unions or incomplete types, etc).

1) objc ivar processing is split out of ActOnField into its own ActOnIvar method.
2) the new objc ivar action takes visibility info directly, eliminating 
  AllVisibilities in ParseObjCClassInstanceVariables.

interaction for function parameters, fixing PR2046.

Patch by Doug Gregor!

llvm-svn: 49369

While it is similar to the other compatibility predicates in ASTContext,
it is not used by them and is different.

In addition, greatly simplify ObjCQualifiedIdTypesAreCompatible and
fix some canonical type bugs.  Also, simplify my Type::getAsObjC* methods.

-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

Change ObjCInterfaceDecl to inherit from NamedDecl (not TypeDecl). While ObjCInterfaceDecl is arguably a TypeDecl, it isn't a ScopedDecl. Since TypeDecl's are scoped, it makes sense to simply treat them as NamedDecl's. I could have fiddled a bit more with the hierarchy (in terms of creating a non-scoped TypeDecl), however this probably isn't worth the effort. 

I also finished unifying access to scope decl change by converting Sema::getObjCInterfaceDecl() to use Sema::LookupDecl(). This is much cleaner now:-)

llvm-svn: 49107

Two changes to Sema::LookupDecl() interface. 
(1) Remove IdLoc (it's never used). 
(2) Add a bool to enable/disable lazy builtin creaation (defaults to true).

This enables us to use LookupDecl() in Sema::isTypeName(), which is also part of this commit.

To make this work, I changed isTypeName() to be a non-const member function. I'm not happy with this, however I fiddled with making LookupDecl() and friends const and it got ugly pretty quickly. We can certainly add it back if/when someone has time to fiddle with it. For now, I thought this simplification was more important than retaining the const-ness. 

llvm-svn: 49087

llvm-svn: 49066

Fairly large "cleaup" related to changing ObjCCompatibleAliasDecl superclass (to inherit from NamedDecl, instead of ScopedDecl). 

- Added a DenseMap to associate an IdentifierInfo with the ObjCCompatibleAliasDecl.
- Renamed LookupScopedDecl->LookupDecl and changed it's return type to Decl. Also added lookup for ObjCCompatibleAliasDecl's.
- Removed Sema::LookupInterfaceDecl(). Converted clients to used LookupDecl().
- Some minor indentation changes.

Will deal with ObjCInterfaceDecl and getObjCInterfaceDecl() in a separate commit...

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.

Set the start of DeclStmt range.  Right now the end is meaningless 
though.

A bunch-o changes to fix <rdar://problem/5716046> incomplete implementation of ObjC class warning is incomplete

As part of this fix, I made a low-level change to the text diagnostics machinery (to basically avoid printing duplicate source lines/carets when you have multiple diagnostics that refer to the same exact place). For now, this only happens with we don't have a source range (could be extended to support source ranges as well).
