Marcel, do you have a copyright assignment with the FSF for GDB?
Without it we can't use your code :-(.  Does this code give some
reasonable testsuite results?  Does it support calling functions from
within GDB?  I never got that working when I was hacking on this.

Kevin.  What's the status of AIX on IA-64?  Isn't it completely dead?

Anyway, Marcel, here are some hints:

* Get rid of the xm-fbsd.h file.

* For the nm-fbsd.h file, I recently factored out some common *BSD
  things.  Also, please move the shared library support stuff to
  tm-fbsd.h.  All you need there is to include "solib.h".  The
  inclusion of "elf/common.h" and the SVR4_SHARED_LIBS shouldn't be
  necessary anymore.  This also means you'll want to move solib.o and
  solib-svr4.o from fbsd.mh to fbsd.mt.  You can drop solib-legacy.o
  if you add:

  set_solib_svr4_fetch_link_map_offsets
      (gdbarch, svr4_lp64_fetch_link_map_offsets);

  to ia64-fbsd-tdep.c:ia64_fbsd_init_abi().

* The code that deals with the registers (taking apart `struct reg'
  and `struct fpreg') shouldn't live in ia64-fbsd-nat.c, but in
  ia64-fbs-tdep.c.  This involves hard coding the offsets of the
  various registers.

* There are various coding-style issues.  Mostly this involves the
  formatting of comments, but there are also GCC-isms like __inline
  that will have to dissappear.

That said, I think you're on the right track with TARGET_OBJECT_DIRTY.
