public interface DeoptBciSupplier

A marker interface for nodes that represent operations that can deoptimize and thus need a BCI to deopt to.

Method Summary

Modifier and Type	Method and Description
int	bci()
void	setBci(int bci) Remember the byte code index (BCI) for code generation or lowering purposes.

Method Detail

bci

int bci()

Returns:

the byte code index (BCI) associated with the node implementing this interface

setBci

void setBci(int bci)

Remember the byte code index (BCI) for code generation or lowering purposes. For example, nodes lowering to foreign calls that can safepoint require a valid BCI for computations of the during-state of such a foreign call.
