Constructor Detail

SimpleInsn

public SimpleInsn(Dop opcode,
          SourcePosition position,
          RegisterSpecList registers)

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

Parameters:

opcode - the opcode; one of the constants from Dops

position - non-null; source position

registers - non-null; register list, including a result register if appropriate (that is, registers may be either ins or outs)

Method Detail

withOpcode

public 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

withRegisters

public DalvInsn withRegisters(RegisterSpecList registers)

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

Specified by:

withRegisters in class DalvInsn

Parameters:

registers - non-null; new register list

Returns:

non-null; an appropriately-constructed instance

argString

protected String argString()

Gets the string form for any arguments to this instance. Subclasses must override this.

Specified by:

argString in class DalvInsn

Returns:

null-ok; the string version of any arguments or null if there are none
