Source lines are labeled with the function from which they came and the line number and source file name. If no line-number information is available for a function, or if the source file for the function is not known, all of the function’s program counters (PCs) appear aggregated into a single entry for the function in the lines display. PCs from functions that are from load-objects whose functions are hidden appear aggregated as a single entry for the load-object in the lines display. Selecting a line in the Lines view shows all the metrics for a given line in the Selection Details window. Selecting the Source or Disassembly view after selecting a line from the Lines view positions the display at the appropriate line.
