Method Summary

Modifier and Type	Method and Description
boolean	canDeoptimize(ForeignCallDescriptor descriptor) Determines if deoptimization can occur during a given foreign call.
LocationIdentity[]	getKilledLocations(ForeignCallDescriptor descriptor) Gets the set of memory locations killed by a given foreign call.
boolean	isReexecutable(ForeignCallDescriptor descriptor) Determines if a given foreign call is side-effect free.
ForeignCallLinkage	lookupForeignCall(ForeignCallDescriptor descriptor) Gets the linkage for a foreign call.

Method Detail

isReexecutable

boolean isReexecutable(ForeignCallDescriptor descriptor)

Determines if a given foreign call is side-effect free. Deoptimization cannot return execution to a point before a foreign call that has a side effect.

getKilledLocations

LocationIdentity[] getKilledLocations(ForeignCallDescriptor descriptor)

Gets the set of memory locations killed by a given foreign call. Returning the special value LocationIdentity.any() denotes that the call kills all memory locations. Returning any empty array denotes that the call does not kill any memory locations.

canDeoptimize

boolean canDeoptimize(ForeignCallDescriptor descriptor)

Determines if deoptimization can occur during a given foreign call.

lookupForeignCall

ForeignCallLinkage lookupForeignCall(ForeignCallDescriptor descriptor)

Gets the linkage for a foreign call.
