Thanks for supporting this!
Besides that I also wonder why all the 64-bit relocations get
marked as LP64-only. It is clear that some of them can be useful
in ILP32 as well, and there's no reason to preclude future uses
even if currently no-one can imagine any.
Furthermore, it seems questionable to continue to require rela
relocations when for all normal ones (leaving aside the 8- and 16-
bit ones) the addend can fit in the relocated field.
Finally, shouldn't R_X86_64_GLOB_DAT and R_X86_64_JUMP_SLOT
also have a field specifier of wordclass rather than word64 (though
'wordclass' by itself would probably be wrong if the tying of the ABI
to the ELF class was eliminated)? And how about R_X86_64_*TP*64
and R_X86_64_TLSDESC?
