...in http://www.mirandabanda.org/files/Cog/VM/VM.r2628. These fix a bug with pc mapping that could cause the Vm to crash on simple loops containing arithmetic on constants (e.g. 1 to: 20 do: [:i| 1=1]). They also cause the instantiation primitives to pop all their arguments rather than assume their argument count is 0 or 1. More change info available in the directory. -- best, Eliot

SystemTracing updated on SqueakMap

I updated the SqueakMap entry for SystemTracing with a new release for Squeak 4.4. This is the latest version that is being used to trace 64-bit images on http://box3.squeak.org/job/Squeak%2064-bit%20image/ The script that is being used for the 64-bit image trace is http://box3.squeak.org/job/Squeak%2064-bit%20image/ws/TraceTo64.st and copied below for reference.
