Field	Kind	Type	Description
Size_In_Bits (from Bit_Field)	attribute	builtin Natural	The size of the bitfield component in bits.
Bit_Position (from Bit_Field)	attribute	builtin Natural	The position in the current storage unit, i.e., the storage unit at Field.Offset.
Offset (from Field)	attribute	builtin Natural	Starting position of this field inside the parent composite. Equal to the value of offsetof(Parent, Field). The Offset does not include the Bit_Position for bit-fields. Note: multiple fields can share the same offset in these circumstances: In a union, all fields will have offset 0. Neighboring bit-fields will have the same offset if they are stored together. C++20 [[no_unique_address]]
Offset_In_Bits (from Field)	attribute	builtin UInt64	Offset to the field in bits. This is equal to offsetof(Parent, Field) * CHAR_BIT. The Offset_In_Bits does not include the Bit_Position for bit-fields.
Its_Type (from Typed_Object)	semantic	class Type	the normalized, ‘underlying’ type
Object_Flags (from Typed_Object)	attribute	bitfield Object_Flags_Type	bits like “address taken” and “is pointer”
Parent (from Logical_IR_Root)	semantic	class Logical_IR_Root
Physical (from Logical_IR_Root)	semantic to physical	class Physical_IR_Root
Visibility (from Member)	attribute	enum Visibility_Type
Name (from Named_Entity)	attribute	builtin String
