Defined in:

Overview

Holds instruction references for an iseq’s optional-argument position table. References are to IR::Instruction objects by identity so they survive instruction-list mutation.

opt_table — Array<IR::Instruction>, one per optional arg plus one terminating entry.
            Each entry points at the instruction where execution begins when
            exactly (lead_num + i) positional args were supplied.
            Format on disk: VALUE[] (8-byte native uint64 YARV slot indices).
