Class CounterArrayManager

java.lang.Object
  extended by org.jikesrvm.compilers.opt.InstrumentedEventCounterManager
      extended by org.jikesrvm.adaptive.measurements.instrumentation.CounterArrayManager
All Implemented Interfaces:
OptConstants, Operators

public final class CounterArrayManager
extends InstrumentedEventCounterManager
implements Operators, OptConstants

An implementation of a InstrumentedEventCounterManager . It uses an unsynchronized two dimensional array of doubles to allocate its counters. (see InstrumentedEventCounterManager.java for a description of a counter manager)

NOTE: Much of this class was stolen from CounterArray.java, which is now gone.

CounterArrayManager

public CounterArrayManager()
Method Detail

registerCounterSpace

public int registerCounterSpace(int countersNeeded)
This method is called by a ManagedCounterData object to obtain space in the counter manager. A handle or "ID" is returned for the data to identify its counter space.

Specified by:
registerCounterSpace in class InstrumentedEventCounterManager
Parameters:
countersNeeded - The number of counters being requested
Returns:
The handle for this data's counter space.

resizeCounterSpace

public void resizeCounterSpace(int handle,
                               int countersNeeded)
Description copied from class: InstrumentedEventCounterManager
This method is called to change the number of counters needed.

Specified by:
resizeCounterSpace in class InstrumentedEventCounterManager
Parameters:
handle - The handle describing which the data to be resized
countersNeeded - The number of counters needed

getCounter

public double getCounter(int handle,
                         int index)
Description copied from class: InstrumentedEventCounterManager
Get the value of a counter.

Specified by:
getCounter in class InstrumentedEventCounterManager
Parameters:
handle - The counter space to look in
index - The counter whose value to return

setCounter

public void setCounter(int handle,
                       int index,
                       double value)
Description copied from class: InstrumentedEventCounterManager
Set the value of a counter.

Specified by:
setCounter in class InstrumentedEventCounterManager
Parameters:
handle - The counter space to look in
index - The counter whose value to return
value - The new value of the counter

createEventCounterInstruction

public Instruction createEventCounterInstruction(int handle,
                                                 int index,
                                                 double incrementValue)
Create a place holder instruction to represent the counted event.

Specified by:
createEventCounterInstruction in class InstrumentedEventCounterManager
Parameters:
handle - The handle of the array for the method
index - Index within that array
incrementValue - The value to add to the counter
Returns:
The counter instruction

mutateOptEventCounterInstruction

public void mutateOptEventCounterInstruction(Instruction counterInst,
                                             IR ir)
Take an event counter instruction and mutate it into IR instructions that will do the actual counting. Precondition: IR is in LIR

Specified by:
mutateOptEventCounterInstruction in class InstrumentedEventCounterManager
Parameters:
counterInst - The counter instruction to mutate
ir - The governing IR

InsertALoadOffset

static RegisterOperand InsertALoadOffset(Instruction s,
