Method Detail

getType

public String getType()

getLinker

public Linker getLinker()

Description copied from class: Frame

The Linker object to use when compiling for this Frame.

Specified by:

getLinker in class Frame

pointersAreLong

public boolean pointersAreLong()

Description copied from class: Frame

Returns false if pointers can be represented in 32 bits, or true otherwise.

Specified by:

pointersAreLong in class Frame

setNoTagCheckMap

public void setNoTagCheckMap(Map hm)

setUsedDANum

public void setUsedDANum(Set hs)

getUsedDANum

public Set getUsedDANum()

memAccessNoTagCheck

public boolean memAccessNoTagCheck(HCodeElement hce)

daNum

public Object daNum(HCodeElement hce)

getCodeGen

public CodeGen getCodeGen()

Returns a MIPS.CodeGen. Since no state is maintained in the returned MIPS.CodeGen, the same one is returned on every call to this method.

Specified by:

getCodeGen in class Frame

getRuntime

public Runtime getRuntime()

Description copied from class: Frame

Returns the appropriate Generic.Runtime for this Frame.

Specified by:

getRuntime in class Frame

getRegFileInfo

public RegFileInfo getRegFileInfo()

Description copied from class: Frame

Returns the appropriate RegFileInfo for this Frame.

Specified by:

getRegFileInfo in class Frame

getLocationFactory

public LocationFactory getLocationFactory()

Description copied from class: Frame

Returns the appropriate LocationFactory for this Frame.

Specified by:

getLocationFactory in class Frame

getInstrBuilder

public InstrBuilder getInstrBuilder()

Description copied from class: Frame

Returns the appropriate InstrBuilder for this Frame.

Specified by:

getInstrBuilder in class Frame

getTempBuilder

public TempBuilder getTempBuilder()

Description copied from class: Frame

Returns the Generic.TempBuilder for the backend associated with this.

Specified by:

getTempBuilder in class Frame

getGCInfo

public GCInfo getGCInfo()

Description copied from class: Frame

Returns the GCInfo for the backend associated with this. null may be returned in some cases. i.e. if precise garbage collection is not supported.

Specified by:

getGCInfo in class Frame

getCodeFactory

public HCodeFactory getCodeFactory(HCodeFactory hcf)

Description copied from class: Frame

Returns a code factory for machine-specific IR.Assems, given a code factory for CanonicalTreeCode. Uses the code generator defined by this frame. Returns null if this frame does not have a code factory that generates IR.Assem.Instrs.

Specified by:

getCodeFactory in class Frame
