You didn't add -xdebugn to md_show_usage.
Also, you didn't update the texinfo docs. gas/doc/c-ia64.texi needs the
exact same changes.
Otherwise this looks OK.
We will have to watch for problems. Even though this is correct, this
may break existing programs which made incorrect assumptions. I know
that gcc and the linux kernel are OK because they always use the -x
option. As for glibc, it looks like it is OK also because it uses gcc
as the assembler.

Generally new options should be mention in the gas/NEWS file as well.
I don't know how significant these options are, so I don't know how
important it is in this case.
Thanks.
