Variable Documentation

_maxVecLengthDouble

constexpr size_t mdLib::_maxVecLengthDouble {highway::MaxLanes(tag_double)}

constexpr

Upper bound on the number of double values in a full register.

Always constexpr.

_vecLengthDouble

HWY_LANES_CONSTEXPR size_t mdLib::_vecLengthDouble {highway::Lanes(tag_double)}

inline

Number of double values in a full register.

Not constexpr on all architectures, so cannot be assumed, but, when possible (e.g. on x86), we provide this constexpr so compilers may make optimizations.
