David T. Lewis uploaded a new version of VMMaker to project VM Maker:

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

Name: VMMaker-dtl.261
Author: dtl
Time: 11 December 2011, 2:21:48.991 pm
UUID: c62d3995-5d8a-4297-b424-704fc8d3b97a
Ancestors: VMMaker-dtl.260

VMMaker 4.7.18

Update primitiveSize to support mirror primitives.
Add missing InterpreterSimulator>>successful method.
Five of six mirror primitive tests pass, but primitivePerformInSuperclass still requires an update (see Mantis 0007429: Add Mirror Primitives to the VM).
