turns out that it could cause an infinite loop in some situations. If this code is triggered and it converts a cleanup into a catchall, but that cleanup was in already in a cleanup, then the _Unwind_SjLj_Resume could infinite loop. I.e., the code doesn't consume the exception object and passes it on to _Unwind_SjLj_Resume. But _USjLjR expects it to be consumed (since it's landing at a catchall instead of a cleanup). So it uses the values that are presently there, which are the values that tell it to jump to the fake landing pad. <rdar://problem/9508402> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@132381 91177308-0d34-0410-b5e6-96231b3b80d8
