If we have a stripped binary and we have no symbols or any other CPU map, and DWARF is the only way to tell if a function was ARM or Thumb by looking at bit zero, then we need to somehow be able to get this raw information.


I would expect there will still be some way to get the raw data, because the dumping tools would want to get it.

However, if I understand things correctly, this is would not be a very useful source of information for us -- on windows arm, all debug info addresses will have the thumb bit set (because everything is thumb), and everywhere else the debug info will have the bit 0 cleared, regardless of whether the function is thumb or not...
