   6 ## We create initial ThunkSection before the gap. Because the ThunkSection
   7 ## selection code isn't so precise, we may create an unused thunk there (0x10704).
   8 ## In the next pass we will create a ThunkSection after the gap. There used to be
   9 ## a bug reusing the first ThunkSection (unreachable) due to the large r_addend.
