I checked in the most recent elf document I have from Hitachi
(it's dated Sep 12 2000), and these reloc. numbers are not used
there.

There's a kind of implication that 128 and higher are used for
Hitachi's non-bit relocations, but only 128-142 have a defined
purpose, and then 160-175 are reserved for dynamic linkage and
224-255 are marked "ignore".

The only other SH ELF system I can think of right now is Greenhills'.
I don't have information on their ELF usage, though I'd
expect they follow the Hitachi usage.

Steve.
