    perf top: Support call-graph display options also · a2c10d39
    Namhyung Kim authored
    Currently 'perf top --call-graph' option is same as 'perf record'.  But
    'perf top' also need to receive display options in 'perf report'.  To do
    that, change parse_callchain_report_opt() to allow record options too.
    
    Now perf top can receive display options like below:
    
      $ perf top --call-graph
        Error: option `call-graph' requires a value
    
       Usage: perf top [<options>]
    
            --call-graph
              <mode[,dump_size],output_type,min_percent[,print_limit],call_order[,branch]>
                         setup and enables call-graph (stack chain/backtrace)
                         recording: fp dwarf lbr, output_type (graph, flat,
    		     fractal, or none), min percent threshold, optional
    		     print limit, callchain order, key (function or
    		     address), add branches
    
      $ perf top --call-graph callee,graph,fp
