}

single taken branch record layout:

  • from: source instruction (may not always be a branch insn)
  • to: branch target
  • mispred: branch target was mispredicted
  • predicted: branch target was predicted

support for mispred, predicted is optional. In case it is not supported mispred = predicted = 0.

  • in_tx: running in a hardware transaction
  • abort: aborting a hardware transaction
  • cycles: cycles from last branch (or 0 if not supported)
  • type: branch type
