    Subject[PATCH 5/6] perf, tool: event parsing - split PE_VALUE_SYM to SW and HW tokens
    Date
    Spliting PE_VALUE_SYM token to PE_VALUE_SYM_HW and PE_VALUE_SYM_SW
    tokens to separate hardware and software symbols.

    This will be usefull in upcomming patches where we want to be able
    to parse out only hardware events.
