Reduce code bloat by removing multiple instantiation of int_writer based on the <typename UInt> parameter. Rationale: - The only functions that gains a speedup by int size would be int_writer::on_dec()'s call to count_digits which uses CLZ. Thus to still take advantage of this speedup, we store the size of the int so we can use a switch statement to call the correct count_digits. - All other implementations of count_digits require some sort of looping that terminates when the value hits zero regardless of what sized int it is. Caveats: - There is a performance hit when dealing with and passing around 64-bit/128-bit values compared to 32-bit values on 32-bit platforms, and with 64-bit values on 64-bit systems. But this should not reduce the performance that dramatically. - There is also a performance hit for on_dec() due to the addition of a switch case. But, due to it size, this should reduce to a jump table. Resolves #1778 |
