--- Comment #8 from Andrew Burgess <andrew.burgess at embecosm dot com> ---

Please could you keep discussion of GDB patches to the GDB mailing list unl=
ess
it is required to move this bug forward.

In this bug I make the claim that the DWARF GCC produces is not correct.  So
far I don't think you are disagreeing with that.

You are, I think, proposing that we should add range end view numbers to the
range table.  I'm not disagreeing that this would solve the problem.

However,

Right now I don't think such a feature is currently in the DWARF standard,
maybe it exists as part of a DWARF proposal?  Or maybe as a GCC extension? =
 I
don't know.

The question I'm asking to the wider GCC community would be, given the (I
claim) current incorrect DWARF, should GCC be changed to produce something
better using existing standard DWARF?  Should a new GCC DWARF extension be
invented?

I certainly don't claim to have the answer here, but hopefully someone else
might have a concrete proposal.=
