Functions
size_t	libff::get_power_of_two (size_t n)
size_t	libff::log2 (size_t n)
	returns ceil(log2(n)), so 1ul<<log2(n) is the smallest power of 2, that is not less than n
size_t	libff::to_twos_complement (int i, size_t w)
int	libff::from_twos_complement (size_t i, size_t w)
size_t	libff::bitreverse (size_t n, const size_t l)
bit_vector	libff::int_list_to_bits (const std::initializer_list< unsigned long > &l, const size_t wordsize)
long long	libff::div_ceil (long long x, long long y)
bool	libff::is_little_endian ()
std::string	libff::FORMAT (const std::string &prefix, const char *format,...)
void	libff::serialize_bit_vector (std::ostream &out, const bit_vector &v)
void	libff::deserialize_bit_vector (std::istream &in, bit_vector &v)
