    perf_counter tools: Provide helper to print percents color · 1e11fd82
    Frederic Weisbecker 提交于
    Among perf annotate, perf report and perf top, we can find the
    common colored printing of percents according to the following
    rules:
    
        High overhead =  > 5%, colored in red
        Mid overhead =  > 0.5%, colored in green
        Low overhead =  < 0.5%, default color
    
    Factorize these multiple checks in a single function named
    percent_color_fprintf() and also provide a get_percent_color()
    for sites which print percentages and other things at the same
    time.
