--- Comment #1 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
That is why it is limited in the first place:
/* Update number of blocks and the estimate for number of insns
in the region. Return true if the region is "too large" for interblock
scheduling (compile time considerations). */
static bool
too_large (int block, int *num_bbs, int *num_insns)
{
(*num_bbs)++;
(*num_insns) += (common_sched_info->estimate_number_of_insns
(BASIC_BLOCK_FOR_FN (cfun, block)));
return ((*num_bbs > param_max_sched_region_blocks)
|| (*num_insns > param_max_sched_region_insns));
}
---- CUT -----
having a more than 10 basic blocks in a region is huge really.
