New Cog VMs available...

... at http://www.mirandabanda.org/files/Cog/VM/VM.r3427.

Squeak V5 users will want to upgrade their VMs because they, along with Smalltalk changes to follow soon, fix image segments.  But upgrading is not a trivial process because the VMs on my site are not complete.  The best way to update is to take a copy of the Squeak 5.0 all-in-one and replace the main VM executable there-in with one from my site.  This gets you up-to-date plugins and an up-to-date VM.  I hope that this process will get easier soon.

CogVM binaries as per VMMaker.oscog-eem.1441/r3427

Modify Spur ImageSegment load to become the segmentWordArray into an Array of

the loaded objects if load is successful, hence decoupling ImageSegment from

the assumption that objects are allocated in order.

Fix Integer receiver, float arg comparison with NaNs in the machine-code

primitive.  This has started failing in the FloatTest>>testNaNCompare since the

new machine-code perform primitive invoked the machine-code version of the

primitive.  The Interpretewr code has always been correct and the old perform

primitive would always run the Interpreter primitive if it exsted, since this

would probably be faster.

Fix the bug introduced by the fix to primitive function invocation in

VMMaker.oscog-eem.1351  The fix correctly changed primitve code to set the

primitiveFunctionPointer appropriately when a jitted external primitive was

rebound, but it didn't remember to void the jit's record of the offset of the

assignment that sets the primitiveFunctionPointer when switching between

profiling andf non-profiling regimes, so that the address from the wrong regime

would remain and be used to smash prmitive code.  The fix is simply to void the

externalSetPrimOffsets in voidCogCompiledCode.  This fixes the bug whose

symptom is a hard VM crash when using AndreasSystemProfilier.

Integrate Marcel Taeumel & Tobias Pape's v2 SSL plugin changes.

Fix negative 64-bit shift in the 64-bit Spur Stack interpreter.

Newspeak:

Fix MNU for cogged self and outer sends.

Make the Newspeak VM packager include the V50 sources file instead of V41.
