Method Detail

getRuntime

public HotSpotGraalRuntimeProvider getRuntime()

getJVMCIRuntime

public HotSpotJVMCIRuntime getJVMCIRuntime()

register

public HotSpotForeignCallLinkage register(HotSpotForeignCallLinkage linkage)

Registers the linkage for a foreign call.

registerStubCall

public HotSpotForeignCallLinkage registerStubCall(HotSpotForeignCallDescriptor descriptor,
                                                  HotSpotForeignCallLinkage.RegisterEffect effect)

Creates and registers the details for linking a foreign call to a Stub.

Parameters:

descriptor - the signature of the call to the stub

registerStubCall

public HotSpotForeignCallLinkage registerStubCall(ForeignCallSignature signature,
                                                  HotSpotForeignCallDescriptor.Transition transition,
                                                  HotSpotForeignCallDescriptor.Reexecutability reexecutability,

public HotSpotForeignCallLinkage registerForeignCall(HotSpotForeignCallDescriptor descriptor,
                                                     long address,
                                                     CallingConvention.Type outgoingCcType)

Creates and registers the linkage for a foreign call. All foreign calls are assumed to have the effect HotSpotForeignCallLinkage.RegisterEffect.DESTROYS_ALL_CALLER_SAVE_REGISTERS since they are outside of Graal's knowledge.

Parameters:

descriptor - the signature of the foreign call

address - the address of the code to call (must be non-zero)

outgoingCcType - outgoing (caller) calling convention type

linkForeignCall

public void linkForeignCall(OptionValues options,
                            HotSpotProviders providers,
                            HotSpotForeignCallDescriptor descriptor,
                            long address,
                            boolean prependThread)

Creates a stub for the foreign call described by descriptor if address != 0.

Parameters:

descriptor - the signature of the call to the stub

address - the address of the foreign code to call

prependThread - true if the JavaThread value for the current thread is to be prepended to the arguments for the call to address

invokeJavaMethodStub
