Don't try to map an APSInt addend to an int64_t in pointer arithmetic before bounds-checking it. This gives more consistent behavior (outside C++11, we consistently use 2s complement semantics for both pointer and integer overflow in constant expressions) and fixes some cases where in C++11 we would fail to properly check for out-of-bounds pointer arithmetic (if the 2s complement 64-bit overflow landed us back in-bounds). In passing, also fix some cases where we'd perform possibly-overflowing arithmetic on CharUnits (which have a signed underlying type) during constant expression evaluation. llvm-svn: 293595 |
