The metafactor C++ library was primarily developed for compile-time factorization of integers up to 32-bit unsigned maximum. As a side-effect, using the algorithms of this library, I could generate big list of primes at compile-time. It turns out that a list of primes less than 65536 (16-bit unsigned integers) can be generated by Clang 3.8 C++ compiler within 5 minutes of compilation time. Apparently, such a list is enough to check any 32-bit unsigned integer for primality or can be used for other purposes. Continue reading →
