The problem is IA64 has
void
ia64_optimization_options (int level ATTRIBUTE_UNUSED,
int size ATTRIBUTE_UNUSED)
{
/* Disable the second machine independent scheduling pass and use one for the
IA-64. This needs to be here instead of in OVERRIDE_OPTIONS because this
is done whenever the optimization is changed via #pragma GCC optimize or
attribute((optimize(...))). */
ia64_flag_schedule_insns2 = flag_schedule_insns_after_reload;
flag_schedule_insns_after_reload = 0;
We didn't handle "-O -fschedule-insns2" properly when after function
specific change. Michael, can you take a look at it? Thanks.
