public final class CodeStatistics
extends Object

Static methods and variables for collecting statistics on generated code.

Field Summary

static int	dexRunningDeltaInsns running sum of the number of dex-form insns (actually code units) added/removed in SSA form by the optimizer.
static int	dexRunningDeltaRegisters running sum of the number of dex-form registers added/removed in SSA form by the optimizer.
static int	dexRunningTotalInsns running sum of the total number of dex insns (actually code units) processed
static int	runningDeltaInsns running sum of the number of insns added/removed in SSA form by the optimizer
static int	runningDeltaRegisters running sum of the number of registers added/removed in SSA form by the optimizer
static int	runningOriginalBytes running sum of original class bytecode bytes
static int	runningTotalInsns running sum of the total number of Rop insns processed

Method Summary

static void	dumpStatistics(PrintStream out) Prints out the collected statistics.
static void	updateDexStatistics(DalvCode nonOptCode, DalvCode code) Updates the dex statistics.
static void	updateOriginalByteCount(int count) Updates the number of original bytecode bytes processed.
static void	updateRopStatistics(RopMethod nonOptRmeth, RopMethod rmeth) Updates the ROP statistics.
