Class MemoryInstr

java.lang.Object

org.ek9lang.compiler.ir.instructions.IRInstr

org.ek9lang.compiler.ir.instructions.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.

Method Details

load

public static MemoryInstr load(String destination,
 String sourceLocation)

Create LOAD instruction: LOAD dest = source_location.

load

public static MemoryInstr load(String destination,
 String sourceLocation,
 DebugInfo debugInfo)

Create LOAD instruction with debug info: LOAD dest = source_location.

store

public static MemoryInstr store(String destinationLocation,
 String source,
 DebugInfo debugInfo)

Create STORE instruction with debug info: STORE dest_location = source.

reference

public static MemoryInstr reference(String variableName,
 String typeInfo)

Create REFERENCE instruction: REFERENCE variable_name, type_info.

reference

public static MemoryInstr reference(String variableName,
 String typeInfo,
 DebugInfo debugInfo)

Create REFERENCE instruction with debug info: REFERENCE variable_name, type_info.

retain

public static MemoryInstr retain(String object,
 DebugInfo debugInfo)
