Yeah, I saw that.  I suspect that this means that the SH maintainer
knows that DWARF is the only debug format in use on the SH.

"dwarf2.h" is not included in many places in gdb, and not by any
header.  So, assuming your uses of this field will end up in truly
generic code, I think the thing to do is introduce a new enum, and
then translate values in the DWARF reader.  It is tempting to simply
reuse the DWARF enum internally, but I think that goes against the GDB
style.
