I am seeing this on my HPPA build as well. David sent me a patch for it off-list and that patch fixed the build problem for me. The patch just reverts Mark's change. The previous code papers over the real problem. The reference to the __gxx_personality_v0 personality function occurs in the eh frame table and not in the exception table. Looking at this a bit, I think the fix is to add if (eh_personality_libfunc) assemble_external_libcall (eh_personality_libfunc); to output_call_frame_info in dwarf2out.c.

That makes sense to me. I think you could do it just in the
for_eh/eh_personality case here:
if (eh_personality_libfunc)
{
*p++ = 'P';
augmentation_size += 1 + size_of_encoded_value (per_encoding);
}
That would emit the reference only in situations where we're actually
going to need the personality routine. The reason for my earlier change
was that we were referencing it even when we'd optimized away all of the
EH information in the module. I'm sorry this broke HP-UX; let me know
if I can help.

Yes, the standard behavior for GNU as/ld on ELF systems is that a .globl emission in the .as file becomes an undefined symbol in the ELF object file, and the linker then pulls in files from an archive to satisfy that reference at link-time, even if there are no relocations against the symbol. One could reasonably argue that the linker shouldn't do this, but it does, and changing it might break things; people may well be relying on this trick. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31322
