Last Branch Record Trace

Last Branch Record (LBR) trace is selected by default the first time you open the
Execution Trace
window .
Note that LBR trace does not use a memory buffer.
To enable it, right-click within the
Execution Trace
window and select
Enable trace
from the context menu. Alternatively, click the trace icon in the
Execution Trac
e window's tool bar.
When LBR trace is enabled, the last 16 taken branches are decoded automatically every time execution stops. Single-stepping is not recommended when the trace is enabled. Instead, set a breakpoint to the interesting location and let the target run to it.
