Constant WIDE 

pub const WIDE: u32 = _; // 1_074_808_092u32

The eight registers that are 64 bits wide; the other 24 are 32-bit.

A bitmask indexed by register number. From UM Table 1-2 (p. 46) and the individual register figures in §5.4 and §6.3: EntryLo0, EntryLo1, Context, BadVAddr, EntryHi, EPC, XContext, ErrorEPC.

There is no rule generating this list — it is exactly the registers that hold an address or a TLB entry. Pinned by the_eight_wide_registers_are_exactly_these.
