--- Comment #11 from rdapp at linux dot vnet.ibm.com ---
416.gamess fails on S390 as well since r254888.
I didn't immediately get what the
if (freq_max < 16)
freq_max = 16;
part of the patch is supposed to achieve. When freq_max < 16, tmp will later be
larger than BLOCK_INFO (bb)->frequency which wasn't the case before. In the
worst case we approach max_count by 4 bits every time.
Why do we need a minimum freq_max? To ensure some scaling even for low
frequencies?
