[parisc-linux] Re: 64-bit long double support.

This has nothing to do with the discussion about long double support.

There's no 64-bit parisc-linux host...

It would appear that the adddi3 expander in pa.md isn't used for some
reason in the initial code expansion as it would reject the insn.  You
are in the best position to determine where the insn is being emitted from.
It could be being emitted from the generic code or the PA backend.  Try
breaks on emit_move_sequence, emit_insn, emit_insn_after or emit_insn_before
and see if you can find where the insn is being emitted.
