- Added wasReferenced function to PseudoConstantAnalysis to determine if a variable was ever referenced in a function (outside of a self-assignment) - BlockDeclRefExpr referenced variables are now explicitly added to the non-constant list - Remove unnecessary ignore of implicit casts - Generalized parameter self-assign detection to detect deliberate self-assigns of variables to avoid unused variable warnings - Updated test cases with deliberate self-assignments - Fixed bug with C++ references and pseudoconstants - Added test case for C++ references and pseudoconstants llvm-svn: 111965
