[PATCH] D24220: [UNWIND] Handle non-existing FDE count / search table

[Joerg Sonnenberger via llvm-commits]

joerg added a comment.

Let me qualify that a bit. A FDE count of 0 can happen, if a DSO absolutely has no FDE entries at all. That's all the short cut that should be needed. A table entry format of DW_EH_PE_omit is only ever valid in combination with FDE count of 0, so that should be an assert at most. I'm trying to remember if table encodings other than sdata4+datarel are valid at all, but I can't find the specification right now.
