    perf stat: Abstract stat metrics printing · 140aeadc
    Andi Kleen 提交于
    Abstract the printing of shadow metrics. Instead of every metric calling
    fprintf directly and taking care of indentation, use two call backs: one
    to print metrics and another to start a new line.
    
    This will allow adding metrics to CSV mode and also using them for other
    purposes.
    
    The computation of padding is now done in the central callback, instead
    of every metric doing it manually.  This makes it easier to add new
    metrics.
    
    v2: Refactor functions, printout now does more. Move
    shadow printing. Improve fallback callbacks. Don't
    use void * callback data.
    v3: Remove unnecessary hunk. Add typedef for new_line
    v4: Remove unnecessary hunk. Don't print metrics for CSV/interval
    mode yet.  Move printout change to separate patch.
    v5: Fix bisect bugs. Avoid bogus frontend cycles printing.
    Fix indentation in different aggregation modes.
    v6: Delay newline handling
