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? Jan
