constexpr FeatureBitset (const std::array< uint64_t, MAX_SUBTARGET_WORDS > &B)

Detailed Description

Container class for subtarget features.

This is a constexpr reimplementation of a subset of std::bitset. It would be nice to use std::bitset directly, but it doesn't support constant initialization.
