Method Detail

getDisplacementForLongIndex

protected static int getDisplacementForLongIndex(TargetDescription target,
                                                 long index)

forEachCounter

protected void forEachCounter(HotSpotCounterOp.CounterProcedure proc,
                              TargetDescription target)

Calls the HotSpotCounterOp.CounterProcedure for each counter in ascending order of their displacement in the counter array.

Parameters:

proc - The procedure to be called

target - Target architecture (used to calculate the array displacements)

getIndex

protected int getIndex(String name,
                       String group,
                       Value increment)

increment -

asLong

private static long asLong(JavaConstant value)

asInt

protected static int asInt(JavaConstant value)

getNames

public String[] getNames()

getGroups
