Sounds like stage2 is miscompiled then.  Can you try the preprocessed source
with
the stage1 compiler and the same flags?

Yes.  I can't duplicate this any more.  I've been updating to
gmp-4.2.3.  Now, I get a build error much earlier:

checking for suffix of object files... configure: error: in
`/test/gnu/gcc/objdi
r/hppa64-hp-hpux11.11/libgcc':
configure: error: cannot compute suffix of object files: cannot compile

This may be the same bug as the one reported here:
http://gcc.gnu.org/ml/gcc/2008-08/msg00500.html

I have been experimenting with IRA:

Had a full bootstrap with this define on hppa2.0w-hp-hpux11.11.  The
define seemed straight forward on the PA.

------- Comment #3 from danglin at gcc dot gnu dot org  2008-08-31 20:30 -------
The problem in comment #2 is the libgmp/libmpfr installation.  I
accidentally installed the shared versions which have a dependency
on libgcc_s.sl.  As a result, the following fails:

configure:2611: /test/gnu/gcc/objdir/./gcc/xgcc -B/test/gnu/gcc/objdir/./gcc/

   conftest.c >&5

The embedded path for libmpfr.sl doesn't include a search path for libgcc_s.sl.

While I didn't specifically try with the preprocessed source, the stage1
compiler has no problem compiling the file with the same flags.

The miscompilation appears when IRA_COVER_CLASSES is defined.

Looking through the test results without it defined, it is a somewhat
surprising that this target builds at all.  There are bitfield and many
problems in struct handling (both layout and argument passing).  The
struct problems appear to have been introduced in late June.
