CLLoadStoreInstruction

public CLLoadStoreInstruction(int opcode,
 int pc)

Constructs a CLLoadStoreInstruction object for LOAD_STORE1 instructions.

Parameters:

opcode - the opcode for this instruction.

pc - index of this instruction within the code array of a method.

CLLoadStoreInstruction

public CLLoadStoreInstruction(int opcode,
 int pc,
 int localVariableIndex,
 boolean isWidened)

Constructs a CLLoadStoreInstruction object for LOAD_STORE2 instructions.

Parameters:

opcode - the opcode for this instruction.

pc - index of this instruction within the code array of a method.

localVariableIndex - index of the local variable to increment.

isWidened - whether this instruction is preceeded by the WIDE (widening) instruction.

CLLoadStoreInstruction
