Constructor Detail

VariableSizeInsn

public VariableSizeInsn(SourcePosition position,
                        RegisterSpecList registers)

Constructs an instance. The output address of this instance is initially unknown (-1).

Parameters:

position - non-null; source position

registers - non-null; source registers

Method Detail

withOpcode

public final DalvInsn withOpcode(Dop opcode)

Returns an instance that is just like this one, except that its opcode is replaced by the one given, and its address is reset.

Specified by:

withOpcode in class DalvInsn

Parameters:

opcode - non-null; the new opcode

Returns:

non-null; an appropriately-constructed instance

withRegisterOffset

public final DalvInsn withRegisterOffset(int delta)

Returns an instance that is just like this one, except that all register references have been offset by the given delta, and its address is reset.

Specified by:

withRegisterOffset in class DalvInsn

Parameters:

delta - the amount to offset register references by

Returns:

non-null; an appropriately-constructed instance
