Returns:

the instance key that represents a particular allocation

getInstanceKeyForMultiNewArray

InstanceKey getInstanceKeyForMultiNewArray(CGNode node,
                                           NewSiteReference allocation,
                                           int dim)

Returns:

the instance key that represents the array allocated as the dim_th dimension at a particular allocation

getInstanceKeyForConstant

<T> InstanceKey getInstanceKeyForConstant(TypeReference type,
                                          T S)

Returns:

the instance key that represents a constant with value S, when considered as a particular type

getInstanceKeyForPEI

InstanceKey getInstanceKeyForPEI(CGNode node,
                                 ProgramCounter instr,
