[Lldb-commits] [PATCH] D18977: Add new ABI callback to provide fallback unwind register locations

[Ulrich Weigand via lldb-commits]

uweigand added a comment.

OK, here's an implementation of the new approach.   In addition to the changes discussed, I had to add handling of undefined register locations -- this might now theoretically also trigger when CFI contains an explicit DW_CFA_undefined, but it should actually do the right thing then as well.

Everything still works on SystemZ using this approach, and I've also tested on Intel with no regressions.
