55 * Decode scope. When parsing a field that is itself a bitset, we push a
56 * new scope to the stack. A nested bitset is allowed to resolve fields
57 * from an enclosing scope (needed, for example, to decode src register
73 * Enclosing scope
101 * would require re-evaluation. But for a given scope, each evaluation
108 * in a given scope to have overlapping cache lookup idx's.
150 * Current topmost/innermost level of scope used for decoding fields,
