Constructor Detail

HotSpotBackend

public HotSpotBackend(HotSpotGraalRuntimeProvider runtime,
                      HotSpotProviders providers)

Method Detail

getRuntime

public HotSpotGraalRuntimeProvider getRuntime()

completeInitialization

public void completeInitialization()

Performs any remaining initialization that was deferred until the runtime object was initialized and this backend was registered with it.

gatherDefinedRegisters

protected static Set<Register> gatherDefinedRegisters(LIR lir)

Finds all the registers that are defined by some given LIR.

Parameters:

lir - the LIR to examine

Returns:

the registers that are defined by or used as temps for any instruction in lir

updateStub

protected void updateStub(Stub stub,
                          Set<Register> destroyedRegisters,
                          Map<LIRFrameState,StandardOp.SaveRegistersOp> calleeSaveInfo,
                          FrameMap frameMap)

Updates a given stub with respect to the registers it destroys.

Any entry in calleeSaveInfo that supports pruning will have destroyedRegisters removed as these registers are declared as temporaries in the stub's linkage (and thus will be saved by the stub's caller).

Parameters:

stub - the stub to update

destroyedRegisters - the registers destroyed by the stub

calleeSaveInfo - a map from debug infos to the operations that provide their callee-save information

frameMap - used to convert a virtual slot to a frame slot index

getStackIntrospection

public StackIntrospection getStackIntrospection()

Specified by:

getStackIntrospection in class Backend

getProviders

public HotSpotProviders getProviders()

Overrides:

getProviders in class Backend

getSuites

Specified by:
