Fix ASTContext::getObjCEncodingForType() to limit the type info for structure bodies (mimics gcc's adhoc rules).
This fixes <rdar://problem/6140902> clang ObjC rewriter: If a class contains a struct ivar with a lot of members, ...

and put the caret on the ()'s.  e.g. produces:

t.c:13:9: error: called object is not a function or function pointer
  ((B)a)();
  ~~~~~~^

instead of:

t.c:13:3: error: called object is not a function or function pointer
  ((B)a)();
  ^~~~~~~~

  getIntegerConstantExprValue where appropriate.

llvm-svn: 54771

 - Returns addr of constant for argument + '\0'.
 - I couldn't think of a better name.
 - Move appropriate users of GetAddrOfConstantString to this.

Rename getStringForStringLiteral to GetStringForStringLiteral.

Add GetAddrOfConstantStringFromLiteral
 - This combines GetAddrOfConstantString and
   GetStringForStringLiteral. This method can be, but is not yet, more
   efficient.

Change GetAddrOfConstantString to not add terminating '\0'
 - <rdar://problem/6140956>

llvm-svn: 54768

Updated checker state printer interface to allow transfer functions to return an arbitrary number of GRState::Printers.

llvm-svn: 54762

The following case resulted in an invalid start location:

// start location not being set for ObjCProtocolDecl AST (when a forward reference is in scope).
@protocol Buggy;

@protocol Buggy 
@optional
- whatever;
@end

llvm-svn: 54740

Rename ValueState.cpp -> GRState.cpp

llvm-svn: 54722

Rename ValueStateManager -> GRStateManager.

llvm-svn: 54721

llvm-svn: 54716

 - Near complete, only properties are missing.

llvm-svn: 54715

llvm-svn: 54714

    ObjCProtocolDecl directly.

Implement CodeGen support for forward protocol decls (no-ops are so
    nice to implement).

Also moved CGObjCRuntime.h out of CodeGenModule.h

Add variadic addInstMethSummary() and refactored addPanicSummary() to use this method. (code reduction).
Misc. cleanups.

llvm-svn: 54694

 - Matches llvm-gcc and seem to be expected by otool.

llvm-svn: 54669

 - Was unused and generated a unnecessary load of self
(missed file)

llvm-svn: 54668

Update NeXT runtime to get proper object & selector types from
       ASTContext.

llvm-svn: 54667

 - Implement type conversion of ObjCQualifiedIdType
 - Wire @protocol(...) to GenerateProtocolRef in ScalarExprEmitter

llvm-svn: 54666

llvm-svn: 54665

llvm-svn: 54664

     InitializePredefinedMacros().
 - Also now properly wired to -fobjc-gc, -fnext-runtime.

llvm-svn: 54661

Changed CGObjCRuntime::GenerateConstantString interface to take
       std::string instead of char* and size.

Change ObjC functions which call on GenerateConstantString to bitcast
       result to appropriate type.

llvm-svn: 54659

llvm-svn: 54654

llvm-svn: 54652

 - Wired to -fnext-runtime and -fgnu-runtime options.
 - Defaults to GNU, no autoselection for NeXT.

Emit NeXT OBJC_IMAGE_INFO marker.

llvm-svn: 54651

 - Changed CodeGenModule::getObjCRuntime to return reference.
 - Added CodeGenModule::hasObjCRuntime predicate.

llvm-svn: 54645

 - Maps to LangOptions.Exceptions
 - Currently always off, should autoselect based on language.

Update CodeGen to set unwind attribute on functions definitions based
       on LangOptions.Exceptions.
 - Still need to set attributes appropriately on calls.

llvm-svn: 54643

llvm-svn: 54642

 - Kill unnecessary #includes in .cpp files. This is an automatic
   sweep so some things removed are actually used, but happen to be
   included by a previous header. I tried to get rid of the obvious
   examples and this was the easiest way to trim the #includes in one
   fell swoop.
 - We now return to regularly scheduled development.

llvm-svn: 54632

 - Drop {Decl.h,DeclObjC.h,IdentifierTable.h} from Expr.h
 - Moved Sema::getCurMethodDecl() out of line (dependent on
   ObjCMethodDecl via dyn_cast).

llvm-svn: 54629

 - Remove internal uses of AST.h

llvm-svn: 54628

 - Drop Expr.h,RecordLayout.h from ASTContext.h (for DeclBase.h and
   SourceLocation.h)
 - Move ASTContext constructor into implementation

llvm-svn: 54627

 - Drop Diagnostic.h from DeclSpec.h, move utility Diag methods into
   implementation .cpp

llvm-svn: 54626

 - Drop TokenKinds.h from Action.h
 - Move DeclSpec.h from Sema.h into individual Sema .cpp files

llvm-svn: 54625

  - Not currently accessible and completely non-functional.

llvm-svn: 54624

  temporarily, I assumed GetAddrForConstantString literal was being
  used consistently but it doesn't look like it is.

Factored out a CodeGenModule::getStringForStringLiteral which handles
  extracting a std::string for the bytes of a StringLiteral, padded to
  match the type.

Update EmitLValue to use getStringForStringLiteral, this was
  previously not padding strings correctly. Good thing we only emit
  strings in 4 different places!

llvm-svn: 54621

* Move FormatError() from TextDiagnostic up to DiagClient, remove now  
  empty class TextDiagnostic
* Make DiagClient optional for Diagnostic

This fixes the following problems:

* -html-diags (and probably others) does now output the same set of  
  warnings as console clang does
* nothing crashes if one forgets to call setHeaderSearch() on  
  TextDiagnostic
* some code duplication is removed
