735cff1fa8 Fixed vsqrt.ss intrinsic usage - order of input operands was wrong. 
Added a test.
Thanks Bruno for reviewing the patch.

b92661d00a [Win32] Catch exceptions (eg. segfault) on waiting for invoked clang from the driver. 
clang/lib/Driver/Driver.cpp: Don't pass through negative exit status, or parent would be confused.

llvm::sys::Program::Wait(): Suppose 0x8000XXXX and 0xC000XXXX as abnormal exit code and pass it as negative value.

Win32 Exception Handler: Exit with ExceptionCode on an unhandle exception.

63f81b112e SCEV fix. In general, Add/Mul expressions should not inherit NSW/NUW. 
This reverts r139450, fixes r139453, and adds much needed comments and a
unit test.

0f9a3f91ae On MachO, the pointer to the personality function should always be in the 
non_lazy_symbol_pointers section (__IMPORT,__pointers). Ignore the 'hidden' part
since that will place it in the wrong section.

7815841fb4 build/cmake: Switch to using llvm-build computed dependencies. 
- I verified locally that the current dependency lists are identical.
 - This makes add_llvm_library_dependencies() a no-op. I'll remove it once this
   change passes the bots.

1d55ba306b Zap some completely ridiculous code. There's probably a miscompile here, but I don't really want to try to write a testcase involving an invoke returning a pointer to a varargs function...

6bf1babd92 Add a link from the LLVM release notes to the Clang release notes. 
I suspect we could profitably remove/move some of the bullet points
under Clang here to the Clang notes in order to keep things clean on
both sides. Unless I hear objections I'll start doing that once folks
have read over the Clang notes a bit.

7c4510b4de edis: Sink EDMain.cpp into lib/MC/MCDisassembler.

473a76a0df Make SelectionDAG::InferPtrAlignment use llvm::ComputeMaskedBits instead of duplicating the logic for globals. Make llvm::ComputeMaskedBits handle GlobalVariables slightly more aggressively, to match what InferPtrAlignment knew how to do.

1435aa5fdc Revert r145273 and fix in SelectionDAG::InferPtrAlignment() instead. 
Conservatively returns zero when the GV does not specify an alignment nor is it
initialized. Previously it returns ABI alignment for type of the GV. However, if
the type is a "packed" type, then the under-specified alignments is attached to
the load / store instructions. In that case, the alignment of the type cannot be
trusted.

567aa3dfb3 DAG combine should not increase alignment of loads / stores with alignment less 
than ABI alignment. These are loads / stores from / to "packed" data structures.
Their alignments are intentionally under-specified.
