(gdb) p regstat_n_sets_and_refs
$1 = (regstat_n_sets_and_refs_t *) 0x0
regstat_n_sets_and_refs is not initialized when sched-pressure perhaps invoking
regstat_init_n_sets_and_refs in sched_init is needed?
This worked with 4.6. The check in print_pseudo_costs was:
for (regno = max_reg_num () - 1; regno >= FIRST_PSEUDO_REGISTER; regno--)
{
if (regno_reg_rtx[regno] == NULL_RTX)
continue;
and has been changed to:
for (regno = max_reg_num () - 1; regno >= FIRST_PSEUDO_REGISTER; regno--)
{
if (REG_N_REFS (regno) <= 0)
continue;
