2011-10-01Hey, maybe we shouldn't silently ignore decl attributesJohn McCall
on declarators written as types. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140931 91177308-0d34-0410-b5e6-96231b3b80d8
2011-10-01constexpr: semantic checking for constexpr functions and constructors. Based inRichard Smith
part on patches by Peter Collingbourne. We diverge from the C++11 standard in a few areas, mostly related to checking constexpr function declarations, and not just definitions. See WG21 paper N3308=11-0078 for details. Function invocation substitution is not available in this patch; constexpr functions cannot yet be used from within constant expressions. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140926 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
2011-09-30Add explicit attributes to mark functions as having had theirJohn McCall
CoreFoundation object-transfer properties audited, and add a #pragma to cause them to be automatically applied to functions in a particular span of code. This has to be implemented largely in the preprocessor because of the requirement that the region be entirely contained in a single file; that's hard to impose from the parser without registering for a ton of callbacks. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140846 91177308-0d34-0410-b5e6-96231b3b80d8
2011-09-29Minor refactoring. Enumerators may inherit the deprecated/unavailable Fariborz Jahanian

2011-09-29c - Enumerators may inherit the deprecated/unavailable Fariborz Jahanian
attributes from the enumeration type. // rdar://10201690 git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140800 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

2011-09-27Revert r139989 and r140031, which implemented the Objective-C typeDouglas Gregor
system change in <rdar://problem/10109725> that allows conversion from 'self' in class methods to the root of the class's hierarchy. This conversion rule is a hack that has non-trivial repurcussions (particularly with overload resolution). git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140605 91177308-0d34-0410-b5e6-96231b3b80d8

correctly pass the information on to Sema. There's still an incorrectness in the way template instantiation works now, but that is due to a far larger underlying representational problem. Also add a test case for various list initialization cases of scalars, which test this commit as well as the previous one. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@140460 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-10When converting a block pointer to an Objective-C pointer type, extendJohn McCall
the lifetime of the block by copying it to the heap, or else we'll get a dangling reference because the code working with the non-block-typed object will not know it needs to copy. There is some danger here, e.g. with assigning a block literal to an unsafe variable, but, well, it's an unsafe variable. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139451 91177308-0d34-0410-b5e6-96231b3b80d8

2011-09-09Contextually converting to 'id' is not a useful operation. ContextuallyJohn McCall
converting to an arbitrary Objective-C pointer type is. Without significantly re-implementing anything, change the API to reflect this, and as a minor optimization, strip the pointer conversion off before potentially building it. Mostly, this removes a really bizarre-looking bit of code from BuildInstanceMessage. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@139354 91177308-0d34-0410-b5e6-96231b3b80d8
