VM Maker: CogTools-sk.84.mcz

commits-2
 
Sophie Kaleba uploaded a new version of CogTools to project VM Maker:
http://source.squeak.org/VMMaker/CogTools-sk.84.mcz

==================== Summary ====================

Name: CogTools-sk.84
Author: sk
Time: 10 August 2017, 3:07:12.537347 pm
UUID: ca5d0d4f-6228-49da-9853-0f10c4234217
Ancestors: CogTools-sk.83

* take into account the modified primitive collectCogCodeConstituents to display the differenciation open/closedPICs
* remove unused method (VMFileSystem, which has been replaced)

To do :
* In the textual report, the display of the number of samples and the cumulated percentages tends to get messy (non aligned) for no reason. I'll try to fix it later

  I am the VMProfiler called when using a Pharo image.
 
  I can only be used headless for the moment.
