I added a `(use (reg:SI 2))' to the return insn to work around this problem.
The build now goes a bit further:

echo "int xxy_us_dummy;" >tmp-dum.c
./xgcc -B./ -B/usr/local/hppa1.1-hp-hpux10.20/bin/ -isystem /usr/local/hppa1.1-h
p-hpux10.20/include -S tmp-dum.c
cc1: Internal error: Segmentation fault.
   Please submit a full bug report.
   See <URL: http://www.gnu.org/software/gcc/bugs.html > for instructions.

This one is in stor-layout.c (layout_type):

void
layout_type (type)
     tree type;
{
  if (type == 0)
    abort ();

   /* Do nothing if type has been laid out before.  */
  if (TYPE_SIZE (type))
    return;

Another problem with regrename?
