Re: [osflash] hamtasc: stacktrace available

[David Rorex]

very nice...now we just need someone to write a tool that will record the entry & exit every time a function is called, as well as a timestamp (from getTimer()), then process all this data to profile your app, giving output similar to the gprof tool.

  %   cumulative   self              self     total           
 time   seconds   seconds    calls  ms/call  ms/call  name    
 17.7       3.72     3.72 13786208     0.00     0.00  Ns_DStringNAppend [8]
  6.1
       5.00     1.28   107276     0.01     0.03  MakePath [10]
  2.9       5.60     0.60  1555972     0.00     0.00  Ns_DStringFree [35]
  2.7       6.18     0.58  1555965     0.00     0.00  Ns_DStringInit [36]
  
2.3       6.67     0.49  1507858     0.00     0.00  ns_realloc [40]

That would be helpful for finding bottlenecks in your code.
