“Next-steps” all threads in the lockstep group associated with the thread of interest that are within the current process over a source line. That is, TotalView lets these threads execute one source line. If the line contains function calls, TotalView executes the entire function as if it were a single statement.
If the process exists, TotalView runs the selected thread until the PC reaches the next address for which it has source line information. If the process does not yet exist, this command launches the process and runs the first thread until the PC reaches the first address for which TotalView has source line information.
While the lockstep group is being run to the next source line, the entire process is also allowed to run. The operation does not complete until all the threads in the lockstep group thread finish stepping, or another thread hits a breakpoint.
For more information on processes and threads and their behavior while being stepped, see “Using Groups, Processes, and Threads” in the “TotalView Users Guide”.
