 - Currently CodeGen always returns a conservative value for this (-1
   or 0 depending on the context).

uses which refer to methods not properties.
 - Not yet wired in Sema.

Add CodeGenFunction::EmitMemSetToZero and make AggExprEmitter::EmitAggregateClear use it.

llvm-svn: 55573

llvm-svn: 55567

 - Change Obj-C runtime message API, drop the ObjCMessageExpr arg in
   favor of just result type and selector. Necessary so it can be
   reused in situations where we don't want to cons up an
   ObjCMessageExpr.
 - Update aggregate binary assignment to know about special property
   ref lvalues.
 - Add CodeGenFunction::EmitCallArg overload which takes an already
   emitted rvalue.

Add CodeGenFunction::StoreComplexIntoAddr.

Disabled logic in Sema for parsing Objective-C dot-syntax that
accesses methods. This code does not search in the correct order and
the AST node has no way of properly representing its results.

Updated StmtDumper to print a bit more information about
ObjCPropertyRefExprs.

llvm-svn: 55561

 - Added CodeGenFunction::EmitCall which just takes the callee, return
   type, and a list of (Value*,QualType) pairs.
 - Added CodeGenFunction::EmitCallArg which handles emitting code for
   a call argument and turning it into an appropriate
   (Value*,QualType) pair.
 - Changed Objective-C runtime interface so that the actual emission
   of arguments for message sends is (once again) done in the code to
   emit a message send.

No intended functionality change, this is prep work for better ABI
support and for Objective-C property setter support.

llvm-svn: 55560

 - Notably VLAs

llvm-svn: 55544

Objective-C property references.
 - This handles property references "more correctly" but setters still
   don't work.

llvm-svn: 55534

 - PR2727.

Also, fix warning in CodeGenTypes for new BlockPointer type.

llvm-svn: 55479

 - Added ASTContext::getObjCEncodingForPropertyDecl.

llvm-svn: 55461

llvm-svn: 55410

Also, fix category protocol list metadata.

llvm-svn: 55405

 - Was emitting duplicates of class properties instead of the category
   properties.

llvm-svn: 55395

Also, fix method lookup to not use LLVM module symbol table.

llvm-svn: 55390

 - Only supports simple assignment and atomic semantics are ignored.
 - Not quite usable yet because the methods do not actually get added
   to the class metadata.
 - Added ObjCPropertyDecl::getSetterKind (one of Assign, Copy, Retain).
 - Rearrange CodeGenFunction so synthesis can reuse function prolog /
   epilog code.

llvm-svn: 55365

correctly.  Not a regression, but made more obvious by my recent fix 
which made function type compatibility checking a bit more strict.

llvm-svn: 55339

Add CodeGenFunction::EmitUnsupportedLValue 
 - Gives error and returns undef value.

Swap some asserts() over to using EmitUnsupportedLValue
 - Rumor has it users (and even some developers) prefer carat
   diagnostics to backtraces.
 - Works better in Release-Asserts to boot.

llvm-svn: 55328

llvm-svn: 55312

EmitScalarConversion().
 - Important for allowing Obj-C void * to id<X> casts and so on.
 - Not sure about this fix however, perhaps Type should understand
   that id is effectively a pointer type.

llvm-svn: 55311

 - NeXT loads the super class at runtime; this required changing the
   runtime interface to pass more information down.

llvm-svn: 55307

llvm-svn: 55304

llvm-svn: 55303

 - This ensures that references to undefined classes cause link
   errors.
 - NOTE: This relies on platform specific asm directives currently,
   this should be factored out.

Also, don't emit a SYMBOLS metadata entry if there are no symbols.

 - Use CodeGenModule::GetAddrOfConstantCFString

Some tweaks of CodeGenModule::GetAddrOfConstantCFString

llvm-svn: 55243

Implement Obj-C lvalue message sends (aggregate returns).

Update several places to emit more precise ErrorUnsupported warnings
  for currently unimplemented Obj-C features (main missing chunks are
  property references, Obj-C exception handling, and the for ... in
  syntax).

llvm-svn: 55234

 - Simplify the sending code a bit.
