Detailed Description

template<typename T, unsigned Bits, bool = std::is_unsigned<T>::value>
struct llvm::bitfields_details::Compressor< T, Bits, bool >

Compressor is used to manipulate the bits of a (possibly signed) integer type so it can be packed and unpacked into a bits sized integer, Compressor is specialized on signed-ness so no runtime cost is incurred.

The pack method also checks that the passed in UserValue is valid.
