Detailed Description

A trace ensemble is a collection of traces selected using the same strategy, for example 'minimum resource height'. There is one trace for every block in the function.

ArrayRef< unsigned > MachineTraceMetrics::Ensemble::getProcResourceDepths ( unsigned MBBNum ) const

protected

Get an array of processor resource depths for MBB. Indexed by processor resource kind, this array contains the scaled processor resources consumed by all blocks preceding MBB in its trace. It does not include instructions in MBB.

Compare TraceBlockInfo::InstrDepth.

ArrayRef< unsigned > MachineTraceMetrics::Ensemble::getProcResourceHeights ( unsigned MBBNum ) const

protected

Get an array of processor resource heights for MBB. Indexed by processor resource kind, this array contains the scaled processor resources consumed by this block and all blocks following it in its trace.

Compare TraceBlockInfo::InstrHeight.

Definition at line 270 of file MachineTraceMetrics.cpp.

MachineTraceMetrics::Trace MachineTraceMetrics::Ensemble::getTrace ( const MachineBasicBlock * MBB )

Get the trace that passes through MBB. The trace is computed on demand.

void MachineTraceMetrics::Ensemble::invalidate ( const MachineBasicBlock * MBB )

Invalidate traces through BadMBB.
