Public Member Functions
auto	ald () const noexcept -> u64
	Return the Access-List Designation (word 2).
auto	asce () const noexcept -> u64
	Return the target address space ASCE (word 1).
auto	authorization_index () const noexcept -> u16
	Return the Authorization Index (AX) from word 0 bits 32–47.
auto	clear () noexcept -> void
	Zero all words.
auto	is_invalid () const noexcept -> bool
	Test the I-bit (invalid) in word 0.
auto	ltd_length () const noexcept -> u8
	Return the linkage-table length (LTL, LTD bits 25-31, 7 bits). Actual table length = (LTL + 1) × 128 bytes.
auto	ltd_origin () const noexcept -> u64
	Return the linkage-table origin as a 31-bit real address. LTD bits 1-24 with 7 zeros appended on the right.
auto	ltd_raw () const noexcept -> u32
	Return the raw 32-bit Linkage-Table Designation (bytes 24-27).
auto	ltd_valid () const noexcept -> bool
	Test the subsystem-linkage control bit (V, LTD bit 0). Must be 1 for PC/PT instructions to proceed.
auto	set_ald (u64 val) noexcept -> void
	Set the Access-List Designation (word 2).
auto	set_asce (u64 val) noexcept -> void
	Set the target address space ASCE (word 1).
auto	set_authorization_index (u16 ax) noexcept -> void
	Set the Authorization Index (AX) in word 0 bits 32–47.
auto	set_invalid (bool inv) noexcept -> void
	Set or clear the I-bit (invalid) in word 0.
auto	set_ltd_length (u8 ltl) noexcept -> void
	Set the linkage-table length (LTL).
auto	set_ltd_origin (u64 addr) noexcept -> void
	Set the linkage-table origin from a 128-byte-aligned real address.
auto	set_ltd_raw (u32 ltd) noexcept -> void
	Set the raw 32-bit Linkage-Table Designation (bytes 24-27).
auto	set_ltd_valid (bool v) noexcept -> void
	Set or clear the V bit in the LTD.
