commits-2
 
Eliot Miranda uploaded a new version of VMMaker to project VM Maker:
http://source.squeak.org/VMMaker/VMMaker.oscog-eem.2057.mcz

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

Name: VMMaker.oscog-eem.2057
Author: eem
Time: 29 December 2016, 9:06:52.675429 am
UUID: 183112c3-adba-4e59-870e-c99e09343e23
Ancestors: VMMaker.oscog-eem.2056

SmartSyntaxPluginSimulator:

Fix several bugs with smart syntax operations (cPtrAsOop asSmallIntegerObj et al) that weren't being simulated.

Delete Object>>primitive: and implement it in SmartSyntaxInterpreterPlugin & SmartSyntaxPluginSimulator to be able to collect the signatures of zero-arg smart syntax prims.

Extend SmartSyntaxPluginSimulator instantiation to include a simulator subclass if one exists (the simulatorClass has to remain SmartSyntaxPluginSimulator to get the wrapping and marshalling on forwarding to work).

Fix returning self in SmartSyntaxPluginSimulator>>doesNotUnderstand:

Implement the ccgLoad:*andThen: methods.

FIx coercion of the byteArrayArg in the FilePluginSimulator read and write methods.
