Function Documentation

QF_LOG2()

std::uint_fast8_t QF_LOG2 ( QP::QPSetBits  x )

noexcept

function that returns (log2(x) + 1), where x is a 32-bit bitmask

Description

This function returns the 1-based number of the most significant 1-bit of a 32-bit bitmask. This function can be replaced in the QP ports, if the CPU has special instructions, such as CLZ (count leading zeros).
