from a conditional branch fed by an add/sub/mul-with-overflow node. We previously used the SDLoc of the overflow node, for no good reason. In some cases, this led to the Bcc and B terminators having different source orders, and DBG_VALUEs being inserted between them. The real issue is with the code that can't handle DBG_VALUEs between terminators: the few places affected by this will be fixed soon. In the meantime, fixing the SDLoc is a positive change no matter what. No tests, as I have no idea how to get .loc emitted for branches? rdar://19347133 git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@228463 91177308-0d34-0410-b5e6-96231b3b80d8
