Not from me! It _is_ dead weight. I wrote on:
<http://sourceware.org/bugzilla/show_bug.cgi?id=8516#c18>
that hpux-thread.c is:
- implemented on top of deprecated_child_ops. deprecated_child_ops is
just a dummy target that does nothing. This was an alternative to removing
hpux-thread.c completely at some point in the past. So this file is just
dead wait at this point, patiently waiting for someone to salvage it.
- implemented as a process_stratum target using the ancient
child_suppress_run hack. Salvaging this target would mean turning it
into a thread_stratum target. I'm looking at the code, and I can
tell you that without adding any new features, just translating the
mechanisms, that most of the file would disappear. The mildly interesting
bits left are the register access code, and the objfile callback that
detects the thread support is active in the inferior. We're talking about
a couple dozens of lines of code.
I wrote a patch getting rid of it at the time, but then never posted it,
waiting for Dave's comments. See below. I see he replied, but for
some reason I didn't see the reply until now... (maybe he replied by
email, and that's been broken, in that it doesn't generate an
email to gdb-prs@...). He doesn't object, so...
