Intel Last Branch Recording (LBR) feature on ARM

Hi Everyone,

I need to know if there is the same of the Last Branch Recording (LBR) hardware feature of the Intel processors on Arm processors for instruction level monitoring during the life-time of a process with minimal overhead.

Thank you.

Not sure what LBR does, but ARM's ETB records "only" branches instead of a full trace.
