org.ek9lang.compiler.ir.MemoryInstr

All Implemented Interfaces:

INode

public final class MemoryInstr
extends IRInstr

Specialized IR instruction for memory operations (LOAD, STORE, ALLOCA, REFERENCE).

Memory instructions handle variable access, allocation, and reference declaration in the EK9 IR.
