Method Detail

quadMap

public Quad quadMap(Quad q)

addQuadMapping

public void addQuadMapping(Quad oldquad,
                           Quad newquad)

tempMap

public Temp tempMap(Temp t)

addDerivation

public void addDerivation(Temp t,
                          Derivation.DList dlist)

derivation

public Derivation.DList derivation(Quad hce,
                                   Temp t)

Description copied from interface: Derivation

Map compiler temporaries to their derivations.

Specified by:

derivation in interface Derivation<Quad>

Parameters:

hce - A definition point for t.

t - The temporary to query.

Returns:

null if the temporary has no derivation (is a base pointer, for example), or the derivation otherwise.

addType

public void addType(Temp t,
                    HClass type)

typeMap

public HClass typeMap(Quad hce,
                      Temp t)

Description copied from interface: TypeMap

Return the type of a given temporary t, as defined at the definition point hce. Iff the type of the temporary is not known, or if hce does not define t, throws TypeNotKnownException. If the temporary represents a derived pointer, null should be returned; in which case the Derivation must return a non-null value. Obviously, TypeMaps for high-level representations without derived pointers should never return null. As a special case, HClass.Void may be returned in low-level IRs to indicate an opaque pointer value which does not correspond to a java object pointer or some derivation thereof --- for example, a pointer into a method dispatch table. The only other time HClass.Void should be returned is for known-null pointer values.

Specified by:

typeMap in interface TypeMap<Quad>

Parameters:

hce - The HCodeElement defining t.

t - The temporary to examine.

Returns:

the static type of t.

clone

public HCodeAndMaps<Quad> clone(HMethod newMethod)

Description copied from class: LowQuadSSI

Clone this code representation. The clone has its own copy of the quad graph.

WARNING: does not preserve derivation or allocation info.

Overrides:

clone in class LowQuadSSI

getName

public String getName()

Description copied from class: LowQuadSSI

Return the name of this code view.

Overrides:

getName in class LowQuadSSI

Returns:

the string "low-quad-ssi"
