2011-10-02Make -fobjc-nonfragile-abi the -cc1 default, since it's theJohn McCall
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. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140957 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-01Allow the results of cf_returns_not_retained functionJohn McCall
calls, or calls to audited functions without an explicit return attribute, to be casted without a bridge cast. Tie this mechanism in with the existing exceptions to the cast restrictions. State those restrictions more correctly and generalize. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140912 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Add an ns_bridged attribute, used to specify that a John McCall
pointer to the annotated struct type can be used as an Objective-C object pointer. If an argument is given, the type is actually "toll-free bridged" to the specific type named there, rather than just to 'id'. For now, we cannot rely on all types being so annotated, and we'll always have to have exceptions for things like CFTypeRef (aka const void*), but this is clearly a good foundation for improving toolage in this area. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140779 91177308-0d34-0410-b5e6-96231b3b80d8
