target/6191: [HP-PA] ICE doing pointer math with -fPIC

Hi all,

this is to confirm that with a gcc 3.3 cvs darwin x
hppa-linux cross compiler, the problem in this PR
still occurs. Compiling the testcase with -fPIC
yields:

junk.i: In function `bad':
junk.i:14: error: unrecognizable insn:
(insn 24 23 25 2 0x0 (set (reg/f:SI 102)
        (plus:SI (reg:SI 19 %r19)
            (high:SI (symbol_ref/v:SI ("@tramp_r")))))
-1 (nil)
    (nil))
junk.i:14: internal compiler error: in extract_insn,
at recog.c:2175
Please submit a full bug report,
with preprocessed source if appropriate.
See <URL:http://gcc.gnu.org/bugs.html> for
instructions.

Cheers,

Dara

junk.i:
extern void tramp_r ();

int bad (void* function)
{

  if (!(((long)function & 3) == (2 & 3))) return 0;

  return
   ((((long *) ((char*)function - 2))[0] == ((long *)
((char*)&tramp_r-2))[0])
    && ((((long *) ((char*)function - 2))[2]) ==
(long)((char*)function - 2 + 16
))
    ? 1 : 0
   );

}
