Make -fobjc-nonfragile-abi the -cc1 default, since it's the increasingly prevailing case to the point that new features like ARC don't even support the fragile ABI anymore. This required a little bit of reshuffling with exceptions because a check was assuming that ObjCNonFragileABI was only being set in ObjC mode, and that's actually a bit obnoxious to do. Most, though, it involved a perl script to translate a ton of test cases. Mostly no functionality change for driver users, although there are corner cases with disabling language-specific exceptions that we should handle more correctly now. llvm-svn: 140957

Mark C++ reference parameters as dereferenceable Because references must be initialized using some evaluated expression, they must point to something, and a callee can assume the reference parameter is dereferenceable. Taking advantage of a new attribute just added to LLVM, mark them as such. Because dereferenceability in addrspace(0) implies nonnull in the backend, we don't need both attributes. However, we need to know the size of the object to use the dereferenceable attribute, so for incomplete types we still emit only nonnull. llvm-svn: 213386

Although we currently have explicit lvalue-to-rvalue conversions, they're not actually frequently used, because ImpCastExprToType only creates a node if the types differ. So explicitly create an ICE in the lvalue-to-rvalue conversion code in DefaultFunctionArrayLvalueConversion() as well as several other new places, and consistently deal with the consequences throughout the compiler. In addition, introduce a new cast kind for loading an ObjCProperty l-value, and make sure we emit those nodes whenever an ObjCProperty l-value appears that's not on the LHS of an assignment operator. This breaks a couple of rewriter tests, which I've x-failed until future development occurs on the rewriter. Ted Kremenek kindly contributed the analyzer workarounds in this patch. llvm-svn: 120890
