[Vm-dev] [commit][2860] CogVM source as per VMMaker.oscog-eem.598

31 Jan 2014

Revision: 2860
Author:   eliot
Date:     2014-01-30 17:38:01 -0800 (Thu, 30 Jan 2014)
Log Message:
-----------
CogVM source as per VMMaker.oscog-eem.598
Author: eem
Time: 30 January 2014, 5:06:23.221 pm
UUID: b85d7330-2ddc-4d90-8592-4e37234f4ac2
Ancestors: VMMaker.oscog-eem.597
Add the revision date to the sourceVersionString.  This may make those annoying
"your VM is out of date" warnings go away when Cog is used for Pharo.
Eliminate declarations for non-existent vars in ScratchPlugin>>primitiveFisheye.
Fix markAndTraceStackPage: for Spur.  Stack references to
forwarders must be followed before calling markAndTrace:.
Fix eliminateAndFreeForwarders; it assumed that no forwarder can reference
a new object after scavenge.  That's not true due to transitive references.
Fix SpurMemoryManager>>become:with:twoWay:copyHash: to follow
the specialObjectsOop if it has been forwarded.
Plugins (and the form print prim):
Fix some egregious oop + 4 and oop + 8 references with the correct
oop + BaseHeaderSize.
Reduce the use of isIntegerObject:.  isWords:, isBytes:
et al fail for immediates anyway.
Use var:type: where appropriate and use symbols for 'char *' et al.
Replace some uses of cCode: 'aFunction(args)' with a send of the
equivalent albeit non-existent selector.  This may allow simulation
at some point in the future.
Fix the isValidSegmentBridge: assert for the last bridge.
Add printLikelyImplementorsOfSelector: for help during debugging.
Modified Paths:
