Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2079.mcz

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

Name: VMMaker.oscog-eem.2079
Author: eem

UUID: 00ef0ca2-fca0-4dc0-baa9-e65e98fda15a
Ancestors: VMMaker.oscog-eem.2078

Slang:
Fix code generation for bitInvert64, fixing recently generated 64-bit sources.
Fix indenting for not.
Fix cogitClass for StackInterpreter[Primitives] to avoid unnecessary CCodeGenerator initialization.
