Yay, I can see this on gcc61.fsffrance.org too.  I will have a look
what is going on.

The problem is that whereas on other platforms, hiphip4 looks like:

hiphip4 (struct S s)
{
  void (*<T29e>) (struct S *) _2;

  <bb 2>:
  _2 = s.f;
  _2 (&s);
  return;
}

on hppa, there is an extra aggregate aggregate variable with an extra
assignment:

hiphip4 (struct S s)
{
  struct S s.0;
  void (*<T2b0>) (struct S *) _3;

  <bb 2>:
  s.0 = s;
  _3 = s.0.f;
  _3 (&s.0);
  return;
}

Thus _3 is not loaded from a PARM_DECL but from the extra VAR_DECL and
ipa-prop.c is not able to associate it with the parameter and I cannot
think of a simple way of doing that (I checked and
DECL_HAS_VALUE_EXPR_P of the parm decl is NULL when ipa-cp analysis
runs so that cannot be used, it seems).

Thus, I'm afraid that the best solution, at least for 4.8, is to xfail
the test for hppa.
