Method Detail

canInlineConstant

public boolean canInlineConstant(Constant c)

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.

Overrides:

canInlineConstant in class AMD64MoveFactory

Parameters:

c - 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)

Overrides:

allowConstantToStackMove in class AMD64MoveFactory

Parameters:

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

Returns:

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

createLoad

public AMD64LIRInstruction createLoad(AllocatableValue dst,
                                      Constant src)

Overrides:

createLoad in class AMD64MoveFactory

createStackLoad

public LIRInstruction createStackLoad(AllocatableValue dst,
                                      Constant src)

Overrides:

createStackLoad in class AMD64MoveFactory
