Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-cb.1619.mcz
==================== Summary ====================
Name: VMMaker.oscog-cb.1619
Author: cb
Time: 7 January 2016, 3:31:37.651 pm
UUID: 6db8b900-9c8b-4328-a246-58ecc53178fb
Ancestors: VMMaker.oscog-eem.1618
Fixed all the instructions in the 3 bytecode sets that needs to be mapped if Immutability is turned on.
I introduced #isMappedIfImmutability, which sets isMapped to true if Immutability is turned on (based on Eliot's suggestion a few months ago)
I also introduced a new needsFrameFunction, called needsFrameIfImmutability:, which does what the name suggests :-)
