I think it is another instance of PR 37565.

------- Comment #2 from sje at cup dot hp dot com  2008-11-13 16:57 -------
This seems to be the first non-386 specific test to use
__attribute__((optimize)).
It doesn't look like a regression, it has never worked but was never tested
before.

The problem is that normally ia64_override_options resets
flag_schedule_insns_after_reload to 0 (and saves the value in
ia64_flag_schedule_insns2).  handle_optimize_attribute calls parse_options and
sets flag_schedule_insns_after_reload to 1 but I don't see where it calls the
target override_options function to reset/check/change flags for specific
targets.

This test no longer fails on IA64.  It looks like the fix was put on the
mainline in time for 4.5.0.  I don't think it is worth porting it back to
the 4.4.* line or earlier releases so I am closing it.
