I don't think anyone is actively working on any ia64 or hpux target.
They're largely considered dead platforms.

I would expect there's several relatively minor issues that could be
fixed without in-depth knowledge of GCC.  However, I'm also aware of
much more difficult issues to address (ICEs related to qsort checking
which indicate a problem in the scheduler descriptions).
