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.
