This patch adds the test for the method calculating the RR. The input/expected
data are generated manually using the following Python3 snippet:
~~~~~
import math
title="mpi_get_montgomery_constant_unsafe"
tt = title + " #{}"
in_data = [ "0f", ... ]
def limb_no(number, bil=64):
return int(math.ceil(int.bit_length(number)/(bil * 1.0)))
def calc_rr(number, bil=64 ):
return '{:x}'.format(pow(pow(2, limb_no(number, bil) * bil), 2, number))
def calc_rr_str(number, prefix=""):
rr64 = calc_rr(number)
rr32 = calc_rr(number, bil=32)
return '{}:"{:x}":"{}":"{}"'.format(prefix,number, rr32, rr64)
print("\n\n".join(["{}\n{}".format(tt.format(in_data.index(v)+1), calc_rr_str(int(v,base=16), title)) for v in in_data]))
