to serve as the entry block.  An empty entry block (just as with an
empty exit block, which we already have) simplifies building analyses on top
of CFGs with very little extra overhead.

Add support for ObjC keyword selectors.

- Add SelectorInfo/SelectorTable classes, modeled after IdentifierInfo/IdentifierTable.
- Add SelectorTable instance to ASTContext, created lazily through ASTContext::getSelectorInfo().
- Add SelectorInfo slot to ObjcMethodDecl.
- Add helper function to derive a SelectorInfo from ObjcKeywordInfo.

Misc: Got the Decl stats stuff up and running again...it was missing support for ObjC AST's.

- Allow classnames as the receiver (removing a FIXME from ParseObjCMessageExpression).
- Added a FIXME to ParseObjCMessageExpression()...we need to return a message expr AST node!

Silenced a couple of VC++ warnings.

this eliminates their dependence on the preprocessor and eliminates some
duplicated code.

Start converting Action methods from Parse-prefix to ActOn-prefix.

The previous naming scheme was confusing, since it resulted in both the Parser and Action modules having methods with the same name. In addition, the Action module never does any parsing...

Rename Action::ParseRecordBody() to ProcessFieldDecls(), and add a visibility argument.

Remove Action::ObjcAddVisibilityToIvars(). No need for an extra API when it is trivial to add this info to the previous hook.

In general, I want to start migrating away from having Actions prefixed with "Parse" (which is confusing, since the Action API doesn't do any parsing, per se).

llvm-svn: 41973

Preliminary implementation of UninitializedValues, which is based on
new solver (doesn't work yet, but compiles).

llvm-svn: 41970

Several improvement to Sema::ParseRecordBody()...

- Adding a safer prologue. The previous prologue would accept a null and therefore assume we had an interface (which was incorrect).
- Fixed FieldDecl's classof method. This allowed me to simplify some unnecessary casting.
- When diagnosing errors, make sure the FieldDecl/EnclosingDecl are marked as invalid. In addition, don't delete the field...rather, add all fields to the enclosing decl. Memory management can/should be done elsewhere. This code was never "upgraded" to the recently added invalid decl strategy.

Now that the dust has settled on the Decl refactoring, I noticed FieldDecl didn't need NextDeclarator.  As a result, I'm removing it. 

Removing both slots (NextDeclarator/Next) end up reducing the size of fields/ivars by 40%.

llvm-svn: 41948

Move Decl::NextDeclarator (w/ setters/getters) down to ScopedDecl/FieldDecl.

Decl is now svelte:-)

llvm-svn: 41935

Phase 2 of making the Decl class more lightweight...

Move Identifier/Loc instance variables (and associated getters/setters) down from Decl to ScopedDecl/FieldDecl.

Objc AST's can now inherit from Decl without getting instance variables and types that are C specific. For now, I am keeping NextDeclarator, since I believe it may be useful to ObjC. If not, it can be moved later.
