non-incremental/QF_BV/brummayerbiere/nextpoweroftwo512.smt2 

We verify the correctness of the ""next power of 2 algorithm""
from the book ""hacker's delight"" (Warren Jr., Henry).

Algorithm:
int next_power_of_2 (int x)
{
  int i;
  x--;
  for (i = 1; i < sizeof(int) * 8; i = i * 2)
  x = x | (x >> i)
  return x + 1;
}

Bit-width: 512
