I am thinking about it. But we don't currently store them. So we would
have reparse them. And since I haven't used them myself I am not sure
what they best way is to expose them. Are you currently using
Dwarf_Frames or Dwarf_CFI_Entry? Could you show some code that uses the
CFI with personality routines and lsda?
