Method Detail

newFrame

public abstract Frame newFrame(java.lang.String name)

mainFrame

public abstract Frame mainFrame()

allocFormal

public abstract Access allocFormal(java.lang.String s)

Allocate a formal parameter named s in this frame.

allocLocal

public abstract Access allocLocal(java.lang.String s)

Allocate a local variable named s in this frame. If s is null, then the variable is forced to be allocated in memory in the frame. If s is non-null, then the variable is eligible for register allocation.

registers

public abstract Temp[] registers()

wordSize

public abstract int wordSize()

external

public abstract Exp external(java.lang.String func)

RV

public abstract Exp RV()

string

public abstract java.lang.String string(Label label,
                                        java.lang.String value)

record

public abstract java.lang.String record(Label label,
                                        int words)

vtable

public abstract java.lang.String vtable(Label label,
                                        java.util.LinkedList<Label> methods)

badPtr

public abstract Label badPtr()

badSub

public abstract Label badSub()

codegen
