OK. Good.

Maybe.

Most likely.

Odd. According to my reading of the the ABI, I believe that code is
correct. The LTOFF_FPTR21L and LTOFF_FPTR14DR relocs should be referencing
the DLT, not accessing the .opd directly.
However, that interpretation directly conflicts with the code you found
in exitcu.o. Ugh.
My ABI is V1.43 Oct 6, 1997.
Could you check the HP web site and see if there's a newer version and
see what formula they give for the LTOFF relocations? You can probably
find it by searching for ELF. You're looking for the
"Processor-Specific ELF Supplement for PA-RISC".
