Mac VM not responding - any ideas?

Dave Lewis uploaded a new version of VMMaker to project VM Maker: http://www.squeaksource.com/VMMaker/VMMaker-dtl.249.mcz ==================== Summary ==================== Name: VMMaker-dtl.249 Author: dtl Time: 21 August 2011, 11:13:53 am UUID: 330dac94-0086-48dd-84ae-496930360e4e Ancestors: VMMaker-dtl.248 VMMaker 4.7.6 Prune unreferenced methods in plugins. Previously this was done only for interpreter classes. Useful when MemoryAccess is used in code generation, in which case unused memory access functions in plugin modules should not be generated. Warning: Plugins that do not declare externally referenced methods (listed in #requiredMethodNames, declared as exported, or equivalent) will have those methods removed by #pruneUnreachableMethods. Externally maintained plugins may encounter this issue. If the plugin cannot be updated, then its module name should be added to InterpreterPlugin class>>doNotPruneClasses, which will disable method pruning for that class. Currently RomePlugin is listed in #doNotPruneClasses. OSProcessPlugin and AioPlugin must be updated to their latest versions from SqueakSource (use 'VMMaker updateFromServer' or equivalent) in order to prevent required methods from being pruned.

This is a fix for SlangTest>>testInterpDeclareStatic. With this update, all VMMaker-Tests tests are green. Implements the following policy: - Always honor a #static: pragma (or 'self static: true' statement). - If not explicitly declared, defer to the code generator to determine default. - Plugin methods are declared static by default (local to the plugin). - Interpreter methods are declared not static by default (visible to support code). This retains existing code generation behavior, but permits methods in the interpreter to be declared static if desired.

Eliot Miranda uploaded a new version of VMMaker to project VM Maker: http://www.squeaksource.com/VMMaker/VMMaker.oscog-eem.117.mcz ==================== Summary ==================== Name: VMMaker.oscog-eem.117 Author: eem Time: 16 August 2011, 2:31:47 am UUID: a21465f6-8cd9-4284-8638-c30d5de21ce9 Ancestors: VMMaker.oscog-eem.116 Cogit: Fix bugs described in the "[Pharo-project] Troubles with #flushCache and #run:with:in:" thread http://lists.gforge.inria.fr/pipermail/pharo-project/2011-July/050858.html. The PIC machinery wrongly treated invoke-as-method sends as MNUs. Closely related, finally fully implement PIC MNU cacheing where, by calling a special abort, a PIC is able to record that a gven selector is an MNU for a particular class. Speeds up a simple MNU benchmark by 33% (with more performance the deeper the receiver's cass hierarchy is). Refactor method cache flushing's interface with the Cogit. If doesNotUnderstand: is ever redefined all closed PICs with MNU cases must be discarded. Change type of JumpLong: and JumpRT args for fewer casts. Comment typos (cePushImplicitReceiver => ceImplicitReceiver). CoInterpreter: fix receivers in primitiveClone. Fix assert failure in cloneContext: by avoiding ObjectMemory>>clone:. refactor printOopShort: and use this in new printMethodDictionary(Of), and also in findString. Slang: Fix translation of $' which needs to become '\''.

Fix assert uses of methodClassAssociationOf: to noAssertMethodClassAssociationOf: in cases where a CogMethod's objectHeader may be invalid (i.e. during relocation). Fix some local variable name conflicts with globals. Add a longPrintOop: that printOopShort's pointer fields. In the Newspeak VM hook up an anonymous method with one of its cogged forms if its original cogged method has been freed. Make the leak checker a little more informative. Use super for CoInterpreterMT>>loadInitialContext.

Fix now obsolete, but still used primitiveContextAt et al (primitives 210, 211 & 212) to be varargs, since these might also be used from mirror primitives. Pull the temporary:in:[put:] code into a non-inlined wrapper to avoid bloating the common case. Cogit/CogObjectRepresentationForSqueakV3: Fix genInnerPrimitiveAt: & genInnerPrimitiveSize to fail for context receivers. Fix genInnerPrimitiveAt:, genInnerPrimitiveStringAt: & genInnerPrimitiveSize to call the interpereter primitive on failure, to get the error code (not yet avoiding the call if the method doesn't use the error code; one thing at a time). Add symbolic constants for accessing instSpec/formatOfHeader:. Make these and their analogues for compact class index access macros. Slang: Fix TStmtListNode as-expression output for the forst or: in InterpreterPrimitives> primitiveSize.
