I know, but I'd like to avoid that number of failures to grow, so I
really think rerunning the testsuite at each patch is useful.

I don't have access to the HPUX tools, so I also test using GCC/GNAT
too.  Michael Chastain, on the other hand, has been giving this
combination several spins. He sends his results from time to time.

Anyway: I verified your patch against the testsuite on HPUX 11 with
both 32bits and 64bits modes. No regression reported. I should note
that I had to modify your patch for two things:
  
  - zero initialize the tdep structure, but allocation using XZALLOC
    instead of the XMALLOC macro.

  - Tweak the patch to add a #include of hppa-tdep.h in
    hppa-hpux-tdep.c. Your patch seems to be dependent on another
    patch which I wasn't able to locate in the gdb-patches archives.
    So I just did this tweak which was good enough for my purpose.
    (oh, and the patch to hppa-tdep.h didn't apply cleanly either -
    for the same reason I would imagine)

(I should also add that I couldn't review your patch, not enough
knowledge about hppa/hpux and not enough time right now to study it.
I hope somebody else will be able to help you there).
