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

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

* 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

Added AssumeSymGT, AssumeSymGE, AssumeSymLT, AssumeSymLE to add some minor improvements to path-sensitivity.  Right now we basically treat 'x > y' and 'x < y' as implying 'x != y', but this restriction will only inevitably apply to our must rudimentary value tracking component (we'll implement more advanced value reasoning later).

Added decl_iterator to DeclStmt to provide an abstract interface to iterate over the ScopedDecls of a DeclStmt.
Updated a few clients of DeclStmt::getNextDeclarator() to use decl_iterator instead.  Will update other clients after additional testing.

ASTContext::getCanonicalType instead (PR2189)

llvm-svn: 54050

Remove call to isSEL and isSEL itself since the call is dead (isObjCObjectPointerType() will never return true for selectors).

llvm-svn: 54034

Only warn about missing/incomplete -dealloc implementations when a class contains a non-SEL, non-IBOutlet ivar that references an ObjC object.

llvm-svn: 54024

This fixes PR 2573: http://llvm.org/bugs/show_bug.cgi?id=2573

llvm-svn: 54009

Use ASTContext::isObjCObjectPointerType() to check if an ivar is a reference to an Objective-C object.

Don't flag dead stores when the result of a preincrement/predecrement is used in an enclosing expression.

Renamed deterministic EvalBinOp to DetermEvalBinOpNN.  This name mangling is unfortunately needed because virtual methods with the same name can be hidden by subclasses.

llvm-svn: 53751

Modified the new EvalBinOpNN to generate states instead of nodes.  This is a much simpler interface and is what clients will want to do.
