Overview

To be used to denote a register (A / X), an argument (data), or a memory data (mem).

Every predicate returns false here, each subclass overrides exactly the one that identifies it. The registers and len carry no payload and are singletons, the remaining subclasses keep theirs in #val.

Direct Known Subclasses

A, ConstVal, Data, Len, Mem, X

Instance Attribute Details

#val ⇒ Integer? (readonly)

Returns The payload of this scalar, whose meaning depends on the subclass: the immediate value for ConstVal, the index for Data and Mem. nil for the singletons.

Returns:

  • (Integer?) —

    The payload of this scalar, whose meaning depends on the subclass: the immediate value for ConstVal, the index for Data and Mem. nil for the singletons.
