You can check out the CVS repository on sourceware.cygnus.com from 000424. I
think I told you how to do it. I haven't been working with my binutils
patches much this month, but I will probably verify them again soon.

I've actually explicitly put an arort() there. If you look at line line 4364
there's a comment that explains why the abort() is there. It can be fixed,
but someone still has to do it. For now, just use -G 0.

I don't know what you're doing wrong. I could objdump it just fine. I
haven't tested with IRIX.

I can't see anything that's obviously wrong with the assembler output either
so it should be fine.

We can use both RELA and REL relocations in the 64-bit ABI. IRIX as tends to
switch from one to another.
