Remove SelectorTable/SelectorInfo, simply store all selectors in the central IdentifierTable.

Rationale:

We currently have a separate table to unique ObjC selectors. Since I don't need all the instance data in IdentifierInfo, I thought this would save space (and make more sense conceptually).

It turns out the cost of having duplicate entries for unary selectors (i.e. names without colons) outweighs the cost difference between the IdentifierInfo & SelectorInfo structures. Here is the data:

Two tables:

*** Selector/Identifier Stats:
# Selectors/Identifiers: 51635 
Bytes allocated:         1999824

One table:

*** Identifier Table Stats:
# Identifiers:   49500
Bytes allocated: 1990316

llvm-svn: 42139

Remove #include of config.h, it is no longer needed.

Progress on message expressions...

- Add ObjcMessageExpr AST node and associated constructors.
- Add SourceLocation's to ActOnKeywordMessage/ActOnUnaryMessage API.
- Instantiate message expressions...
- Replace alloca usage with SmallString.

Next step, installing a correct type, among other tweaks...

Moves such argument as the last argument and uses defaul value.

llvm-svn: 42073

instead for @protocol method decls.

llvm-svn: 42070

llvm-svn: 42060

Finish defining Action API for message expressions.

llvm-svn: 42059

- Refactored ObjcKeywordInfo into ObjcKeywordInfo, ObjcKeywordDecl, and ObjcKeywordMessage.
- Removed helper ObjcGetSelectorInfo(), moving the code directly into ObjcBuildMethodDeclaration().
- Many refinements to ParseObjCMessageExpression().
- Add ActOnMessageExpression().

Next step, finish the message actions and (finally) create/instantiate an ObjcMessageExpr AST.

llvm-svn: 42050

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.
llvm-svn: 42023

llvm-svn: 42014

- 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.

Switch -parse-ast over to it.

llvm-svn: 41991

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...

llvm-svn: 41986

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

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.

llvm-svn: 41934

llvm-svn: 41932

Add "ScopedDecl" AST, used by ValueDecl and TypeDecl. 

This allows us to sink the "Next" field, which isn't used by FieldDecl and ObjcIvarDecl.
