2012-09-13Promote the warning about extra qualification on a declaration from aDouglas Gregor
warning to an error. C++ bans it, and both GCC and EDG diagnose it as an error. Microsoft allows it, so we still warn in Microsoft mode. Fixes <rdar://problem/11135644>. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163831 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-13[ms-inline asm] Handle the enumeration of input and output expressions in aChad Rosier
more robust way to address a few FIXMEs. The initial implementation, r163342, built the IR asm string and then tried to patch things on the fly without enough context. Specifically, it didn't skip mnemonics nor did it track with assembly instruction an expression was related to. The new implementation patches the operands and then builds the final IR string. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163756 91177308-0d34-0410-b5e6-96231b3b80d8

2012-09-12[analyzer] Fix another use of the address of a temporary, like r163402.Jordan Rose

2012-09-12[analyzer] Re-add reinterpret_cast virtual call test case from r163644.Jordan Rose

2012-09-12[analyzer] Handle when the dynamic type is worse than the static type.Jordan Rose
Currently we don't update the dynamic type of a C++ object when it is cast. This can cause the situation above, where the static type of the region is now known to be a subclass of the dynamic type. Once we start updating DynamicTypeInfo in response to the various kinds of casts in C++, we can re-add this assert to make sure we don't miss any cases. This work is tracked by <rdar://problem/12287087>. In -Asserts builds, we will simply not return any runtime definition when our DynamicTypeInfo is known to be incorrect like this. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163745 91177308-0d34-0410-b5e6-96231b3b80d8
2012-09-12Revert "[analyzer] Use the static type for a virtual call if the dynamic ↵Jordan Rose
type is worse." Using the static type may be inconsistent with later calls. We should just report that there is no inlining definition available if the static type is better than the dynamic type. See next commit. This reverts r163644 / 19d5886d1704e24282c86217b09d5c6d35ba604d. git-svn-id: https://llvm.org/svn/llvm-project/cfe/trunk@163744 91177308-0d34-0410-b5e6-96231b3b80d8
