// primetab.cpp - written and placed in the public domain by Jeffrey Walton
//
// nbtheory.cpp originally built the prime table on the fly, and then
// returned a reference to it in a Singleton. This was useful to
// save memory in the old days. Nowadays we can precompute the table
// and place it in the read-only data segment. Also see
// https://github.com/weidai11/cryptopp/issues/1210.
// The table below was generated from the original Crypto++ table:
//
// $ cat test.cxx
// #include <iostream>
// #include <iomanip>
// #include <sstream>
// #include "config.h"
// #include "nbtheory.h"
//
// int main(int argc, char* argv[])
// {
// using namespace CryptoPP;
//
// unsigned int primeTableSize = 0;
// const word16* primeTable = NULLPTR;
// primeTable = GetPrimeTable(primeTableSize);
//
// for (size_t i=0; i<primeTableSize; ++i)
// {
// std::cout << primeTable[i];
// if (i != primeTableSize - 1)
// std::cout << ", ";
// }
// std::cout << std::endl;
//
// return 0;
// }
