Bug on PA-RISC

[Karl Bolingbroke]

Hi,
I ran across a bug when GCC 3.1 is used on HP-UX with a
combination of the "-mpa-risc-2-0" flag and either "-O2" or
"-O3".  I ran across it in the GNU binutils package and
several other places before I tracked it down.  Here is the
gcc output, and I've attached the .i file.  Let me know if
you need anything else.
