commits-2
 
Sophie Kaleba uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-sk.2261.mcz

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

Name: VMMaker.oscog-sk.2261
Author: sk
Time: 10 August 2017, 11:03:27.62493 am
UUID: 2502e8bf-7a6c-4656-ab61-b3da8e6f5199
Ancestors: VMMaker.oscog-eem.2260

Modify the profiling primitive cogCodeConstituents: to be able to differentiate the closedPICs from the openPICs in the profiling report
