Hi All,

�� �� recent instability seems to have been cured.�� Please find new VMs at��http://www.mirandabanda.org/files/Cog/VM/VM.r3266.�� For Squeakers, these are close to release candidates for the upcoming 5.0 release.�� I have one last modification to do with free space handling on start-up in Spur (the current VMs over-allocate free space), and maybe a minor speed-up of the LargeIntegersPlugin; other than that I intend bug fixes only.

CogVM binaries as per VMMaker.oscog-eem.1085/r3266

Avoid duplication in fetching active process and scheduler in process-switch machinery.

Take advantage of endianness for simpler large integer initialization.

Simplify primitiveMakePoint. Include primitiveMethodXray to introspect on Cog state of methods.

Refactor positive32BitIntegerFor: and signed32BitIntegerFor: in the realization that these

reduce to essentially integerObjectOf: in 64-bit Spur.�� The idea is to inline if in 64-bit Spur

but not if in the 32-bit VMs.�� Add notOption: processing to allow excluding

noInlineSigned32BitIntegerFor: et al.�� Add hasSixtyFourBitImmediates to no longer assume that

wordSize = 8 implies 64-bit immediates.

Use positiveMachineIntegerFor: in place of positive32BitIntegerFor: in some plugins.

Simplify primitiveDisplayString given isArray:.

Simplify two B3DAcceleratorPlugin prims given topRemappableOop and isArray:

Slang:

Changes to type inferrence/propagation and inlining to better support 64-bit Spur.

See change log of VMMaker.oscog in 1067-1085 range for exhaustive details.
