public LIRInstruction createMove(AllocatableValue dst,
                                 Value src)

Specified by:

createMove in class MoveFactory

createStackMove

public LIRInstruction createStackMove(AllocatableValue result,
                                      AllocatableValue input)

Specified by:

createStackMove in class MoveFactory

createLoad

                                        Constant src)

Specified by:

createLoad in class MoveFactory

createStackLoad

public LIRInstruction createStackLoad(AllocatableValue result,
                                      Constant input)

Specified by:

createStackLoad in class MoveFactory

canInlineConstant

public boolean canInlineConstant(Constant con)

Description copied from class: MoveFactory

Checks whether the supplied constant can be used without loading it into a register for most operations, i.e., for commonly used arithmetic, logical, and comparison operations.

Specified by:

canInlineConstant in class MoveFactory

Parameters:

con - The constant to check.

Returns:

True if the constant can be used directly, false if the constant needs to be in a register.

allowConstantToStackMove

public boolean allowConstantToStackMove(Constant value)

Specified by:

allowConstantToStackMove in class MoveFactory

Parameters:

value - The constant that might be moved to a stack slot.

Returns:

true if constant to stack moves are supported for this constant.
