    perf tools: Add a "dso_size" sort order · b74d12d5
    Kim Phillips 提交于
    Add DSO size to perf report/top sort output list.
    
    This includes adding a map__size fn to map.h, which is
    approximately equal to the DSO data file_size:
    
      DSO				file size	map (end-start)	file / (end-start)
      libwebkit2gtk-4.0.so.37.24.9	43260072	41295872	95%
      libglib-2.0.so.0.5400.1		 1125680	 1118208	99%
      libc-2.26.so			 1960656 	 1925120	101%
      libdbus-1.so.3.14.13		  309456 	  303104	102%
    
    Sample output:
    
      $ ./perf report -s dso_size,dso
      Samples: 2K of event 'cycles:uppp', Event count (approx.): 128373340
