echo "\nNotes:"
echo "  - GCC is significantly slower than Clang on multiprecision arithmetic."
echo "  - The simplest operations might be optimized away by the compiler."
echo "  - Fast Squaring and Fast Multiplication are possible if there are spare bits in the prime representation (i.e. the prime uses 254 bits out of 256 bits)"
