Eliot Miranda uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2307.mcz ==================== Summary ==================== Name: VMMaker.oscog-eem.2307 Author: eem Time: 5 January 2018, 12:07:17.508019 am UUID: bede75bd-3b6a-49d4-b6a8-14325d3573c7 Ancestors: VMMaker.oscog-eem.2306 Refactor preDeclareInterpreterProxyOn: to extract collecting the InterpreterProxy interface to its own method to simplify consistency checking. To make the checking more correct use a concrete Sour class for the referenceObjectMemoryClass. Fix several InterpreterProxy interface methods that don't specify a return type. =============== Diff against VMMaker.oscog-eem.2306 =============== Item was changed: ----- Method: InterpreterProxy>>become:with: (in category 'other') ----- become: array1 with: array2 + <returnTypeC: #sqInt> array1 elementsExchangeIdentityWith: array2!
