Method Detail

created

public static int created()

Return the number of instances of this class created.

specifyRegisterUsage

public void specifyRegisterUsage(RegisterAllocator rs,
                                 int index,
                                 int strength)

Specify the registers used by this instruction.

Overrides:

specifyRegisterUsage in class Marker

Parameters:

rs - is the register set in use

index - is an index associated with the instruction

strength - is the importance of the instruction
