Method Detail

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

getCodeGen

public CodeGen getCodeGen()

Returns a StrongARM.CodeGen. Since no state is maintained in the returned StrongARM.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
