The patch which caused the regression is
Tue Apr 30 09:31:59 2002 Jeffrey A Law (law@cygnus.com)
* pa.c (override_options): Default to PA8000 scheduling.
* doc/invoke.texi (HP-PA options): Mention newly added 7300
scheduling parameter.
At first glance, it seems totally unrelated to the problem but the test
fails with -mschedule=8000 (default) and passes with -mschedule=7100.
