Yes. But the function will call:

get_hot_bb_threshold ()
{
  if (min_count == -1)
    {
      gcov_type t = profile_info->sum_max / PARAM_VALUE (HOT_BB_COUNT_FRACTION);
      set_hot_bb_threshold (t);
...

which will cause a segfault in non-PGO run. Note that:
static gcov_type min_count = -1;

is a non-exported variable so that's why I simply added the getter.

Hope it's fine as is?
