David T. Lewis uploaded a new version of VMMaker to project VM Maker: http://source.squeak.org/VMMaker/VMMaker-dtl.340.mcz
==================== Summary ====================
Name: VMMaker-dtl.340 Author: dtl Time: 11 February 2014, 8:04:47.752 pm UUID: 640fa600-e4e0-4cdd-ae74-c6cf1b51b763 Ancestors: VMMaker-dtl.339
VMMaker 4.13.2
For primitiveAllObjects, move the allObjects logic to ObjectMemory.
Incorporate various oscog code generation improvements, including code generation for sending #value: to a block, and elimination of unnecessary temp vars in inlining, for example, generate this:
thisWord = long32At(sourceIndex);
instead of this:
idx7 = sourceIndex; thisWord = long32At(idx7);
A note concerning the code generation - This update results in a regression in that some inlined methods are no longer being inlined, for example fetchClassOf: should be inlined within findSelectorOfMethod:forReceiver: but this is now retained as a function call. I have not identified the reason for the regression, however this update gives a significant reduction in unneeded temporary variable generation, which is an important improvement. Credit for the reduction in temporary variables goes to Eliot, and blame for the inlining regression is mine.
