harpoon.Instrumentation.AllocationStatistics
Class InstrumentAllocs

java.lang.Object
  harpoon.Analysis.Transformation.MethodMutator
      harpoon.Instrumentation.AllocationStatistics.InstrumentAllocs

All Implemented Interfaces:

Serializable

public class InstrumentAllocs
extends MethodMutator
implements Serializable

InstrumentAllocs adds calls to instrumenting code to each allocation site and, if explicitly requested, to each synchronization instruction. If call chain sensitivity is requested, instrumentation is added around method calls to. The produced code prints the instrumentation statistics at the end of the program.

Constructor Detail

InstrumentAllocs

public InstrumentAllocs(HCodeFactory parent,
                        HMethod main,
                        Linker linker,
                        AllocationNumbering an,
                        boolean syncs,
                        boolean callchains)

Creates a InstrumentAllocs.

Parameters:

parent - HCodeFactory that provides the code to instrument

main - main method of the instrumented program

linker - linker for the code to instrument

an - AllocationNumbering for the allocation/call sites

syncs - if true, then the synchronization operations are instrumented too.

callchains - if true, the instrumented code will record the call chains for ecah execution of the instrumented instructions.

Method Detail

getMethod

public static HMethod getMethod(Linker linker,
                                String clsn,

                                HClass[] atypes)

Returns that method of class clsn that is called mn and has arguments of types a_types.

mutateHCode

protected HCode mutateHCode(HCodeAndMaps input)

Description copied from class: MethodMutator

Override this method to effect transformations on split methods.
