The Alpha EV7 On-Chip Logic Analyzer (OCLA) utility collects
    Program Counter (PC) traces in a portion of the Alpha EV7 cache.
    This data enables the user to tell which instructions each Alpha
    EV7 CPU on the system has executed.

    When entered by itself with no command keyword, the OCLA command
    lists the OCLA command options.

                                   NOTE

       dump, the only OCLA commands you can use are OCLA SHOW
       STATUS and OCLA SHOW TRACE.
