RegisterSet (B2R2)

RegisterSet Type

Namespace: B2R2.Collections
Assembly: B2R2.Core.dll
Base Type: obj

Represents a set of register IDs. This is an efficient and architecture-agnostic set data structure that internally uses bit arrays. Since RegisterIDs always start from 0 for any architecture, we can use it directly as an index to the bit array.
