Strategies for selecting traces.
Declared in <llvm/CodeGen/MachineTraceMetrics.h>
enum class MachineTraceStrategy : int;| Name | Description |
|---|---|
TS_MinInstrCount | Select the trace through a block that has the fewest instructions. |
TS_Local | Select the trace that contains only the current basic block. For instance, this strategy can be used by MachineCombiner to make better decisions when we estimate critical path for in-order cores. |
TS_NumStrategies | Select the trace that contains only the current basic block. For instance, this strategy can be used by MachineCombiner to make better decisions when we estimate critical path for in-order cores. |
