Declaration

struct Bitfield::Element { /* full declaration omitted */ };

Description

Describes an element of a Bitfield. This type is then used with the Bitfield static member functions.

Declared at: llvm/include/llvm/ADT/Bitfields.h:223

Templates

T

The type of the field once in unpacked form.

unsigned int Offset

The position of the first bit.

unsigned int Size

The size of the field.

T MaxValue = std::is_enum<type-parameter-0-0>::value ? type-parameter-0-0(0) : std::numeric_limits<type-parameter-0-0>::max()

For enums the maximum enum allowed.
