genmodes.c is miscompiled by stage1/xgcc -B stage1/ at -O1 and higher.
The output of build/genmodes -h is then:
/* Generated automatically from machmode.def and config/rs6000/rs6000-modes.def
by genmodes. */
#ifndef GCC_INSN_MODES_H
#define GCC_INSN_MODES_H
enum machine_mode
{
VOIDmode, /* machmode.def:146 */
BLKmode, /* machmode.def:150 */
CCmode, /* machmode.def:178 */
CCUNSmode, /* config/rs6000/rs6000-modes.def:38 */
CCFPmode, /* config/rs6000/rs6000-modes.def:39 */
CCEQmode, /* config/rs6000/rs6000-modes.def:40 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
BImode, /* machmode.def:153 */
QImode, /* machmode.def:158 */
and those two lines repeat forever.

I think this is fixed by:
2004-10-08 Michael Matz <matz@suse.de>
* loop-doloop.c (doloop_optimize): Extend count.
Can you try after that patch if you don't have that patch installed already?

Thanks a lot, you're right, this patch cures this.
You have saved me from debugging it...
