David T. Lewis uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker-oscog-dtl.124.mcz
==================== Summary ====================
Name: VMMaker-oscog-dtl.124
Author: dtl
Time: 7 September 2011, 7:47:23.321 am
UUID: 22506b93-842d-45e3-b57d-42b84f1657ae
Ancestors: VMMaker.oscog-eem.123
Support plugins (e.g FreetypePlugin) that use #bytesPerWord or #baseHeaderSize by adding these selectors to the C translation dictionary.
These changes produce no change to generated code for the VM except for the case of 'self bytesPerWord' which is now translated to the expected 'BytesPerWord' on oscog.
Class variables BytesPerWord and BaseHeaderSize (and others) do not exist in trunk VMMaker. These are now controlled at compile time rather than at C code generation time to support support a single generated code base for 32/64 bit object memory VMs.

+ A TMethod is a translation method, representing a MethodNode that is to be translated to C source. It has a parseTree of translation nodes that mirrors the parse tree of the corresponding Smalltalk method.!

+ A TParseNode is node in the parse tree of a TMethod. Subclasses correspond to different types of nodes in a method parse tree. The tree of translation parse nodes mirrors the parse tree of a Smalltalk method, and is used for translating a Smalltalk method to C source.!
