* APInt: Make self-move-assignment a no-op to fix stage3 clang-clReid Kleckner2014-08-121-0/+17
| | | | | | | | | | | | | | | | | | | | | | It's not clear what the semantics of a self-move should be. The consensus appears to be that a self-move should leave the object in a moved-from state, which is what our existing move assignment operator does. However, the MSVC 2013 STL will perform self-moves in some cases. In particular, when doing a std::stable_sort of an already sorted APSInt vector of an appropriate size, one of the merge steps will self-move half of the elements. We don't notice this when building with MSVC, because MSVC will not synthesize the move assignment operator for APSInt. Presumably MSVC does this because APInt, the base class, has user-declared special members that implicitly delete move special members. Instead, MSVC selects the copy-assign operator, which defends against self-assignment. Clang, on the other hand, selects the move-assign operator, and we get garbage APInts. llvm-svn: 215478

* [APInt] Fixed bug where APInt(UINT32_MAX, 0) would blow up when being ↵Michael Gottesman2014-01-191-0/+8
| | | | | | | | | | | | | | constructed. This was due to arithmetic overflow in the getNumBits() computation. Now we cast BitWidth to a uint64_t so that does not occur during the computation. After the computation is complete, the uint64_t is truncated when the function returns. I know that this is not something that is likely to happen, but it *IS* a valid input and we should not blow up. llvm-svn: 199609

* ADT: Correct APInt::getActiveWords for zero valuesMeador Inge2013-02-071-0/+8
| | | | | | | | | | PR15138 was opened because of a segfault in the Bitcode writer. The actual issue ended up being a bug in APInt where calls to APInt::getActiveWords returns a bogus value when the APInt value is 0. This patch fixes the problem by ensuring that getActiveWords returns 1 for 0 valued APInts. llvm-svn: 174641

Positive approximations require fewer operations beyond the multiplication. In the case of division by 3, we still generate code that is a single instruction larger than GCC's code. llvm-svn: 126097
