[PATCH] D102511: Do actual DCE in LoopUnroll

[Florian Hahn via Phabricator via llvm-commits]

fhahn added a comment.

It looks like this is causing Clang to crash when building the C source below with `-O3` on X86 (https://bugs.llvm.org/show_bug.cgi?id=50354)

  int a, b, c;
  int main () {
    while (b)
      for (c = -9; c; c++)
        a = (a ^ 2) == 0;
    return 0;
  }
