------- Comment #1 from dave at hiauly1 dot hia dot nrc dot ca 2009-10-14 12:29 -------
Subject: Re: g++.dg/debug/dwarf2/icf.C
One thing that may be relevant is the PA backend doesn't currently
provide vtable support when generating jumps to thunks.

------- Comment #3 from ccoutant at gcc dot gnu dot org 2009-10-17 00:30 -------
The insn UID is changed when the call_insn is split, so the vtable slot index
can't be found when it's time to build the vcall table.

So, it seems this is a middle-end bug.

I'm inclined to classify this as a debug problem rather than middle-end. Does
that seem reasonable?
Steve, could you see if this patch fixes the failure on PA and Itanium?

I haven't had a chance to test it on PA yet but it fixes the problem on
Itanium.

It fixes the test on hppa64-hp-hpux11.11. Will test hppa2.0w-hp-hpux11.11
tonight.
