Classes
class	Ensemble
	A trace ensemble is a collection of traces selected using the same strategy, for example 'minimum resource height'. More...
struct	FixedBlockInfo
	Per-basic block information that doesn't depend on the trace through the block. More...
struct	InstrCycles
	InstrCycles represents the cycle height and depth of an instruction in a trace. More...
struct	LiveInReg
	A virtual register or regunit required by a basic block or its trace successors. More...
class	Trace
	A trace represents a plausible sequence of executed basic blocks that passes through the current basic block one. More...
struct	TraceBlockInfo
	Per-basic block information that relates to a specific trace through the block. More...

MachineTraceMetrics::~MachineTraceMetrics	(	)

void MachineTraceMetrics::clear	(	)

Get the scaled number of cycles used per processor resource in MBB.

This is an array with SchedModel.getNumProcResourceKinds() entries. The getResources() function above must have been called first.

These numbers have already been scaled by SchedModel.getResourceFactor().
