Detailed Description

template<typename T, unsigned Offset, unsigned Size, T MaxValue = std::is_enum<T>::value ? T(0) : std::numeric_limits<T>::max()>
struct llvm::Bitfield::Element< T, Offset, Size, MaxValue >

Describes an element of a Bitfield.

This type is then used with the Bitfield static member functions.

Template Parameters

T	The type of the field once in unpacked form.
Offset	The position of the first bit.
Size	The size of the field.
MaxValue	For enums the maximum enum allowed.
