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
