I think the best way to shrink is for the garbage collector to do it. There's an alternate version of the GC in Spoon[1], invoked with Interpreter>>primitiveSnapshotWithoutStaleMethods. It sets a mark bit on all the methods associated with contexts in extant processes, along with any other methods which have run (for example, by running unit tests). Then it treats all other methods as garbage in the pre-snapshot GC. This leads to a chain reaction; the methods that aren't marked are usually the only things referring to their literals (including classes). The process is immediate, and requires no knowledge of what's being thrown away. The only difference between producing a minimal system (currently 1kB) and a larger one (e.g., the Spoon development base system at 300 kB) is how many methods you mark in advance by running them. -C [1] http://netjam.org/spoon/releases/current -- Craig Latta www.netjam.org/resume +1 510 984 8117 (Skype rings this until 31 January 2014) -- -- Craig Latta www.netjam.org/resume +1 510 984 8117 (Skype rings this until 31 January 2014)

quick update
by Noah Evans 13 Feb '13

13 Feb '13

I have it blitting and receiving mouse and keyboard events. I'm still getting extremely strange floating point behavior (although it may very well be more general). My vm is getting the receiver argument order wrong on the stack. This is leading to divide by zeros. Is there any obvious way of debugging this? I am moving to the VM list after this question, but I wanted to make sure I haven't forgotten something obvious. rcvr 1023.000000 arg 0.000000 >34086640red >34086536mixed:with: >34086444asColor >34086352fillStyle: >34085308updateColor >34084320extent: >34084228width: >34083632updateExtent >34083540updateBounds >34083448ownerChanged >34083356doLayoutIn: >34082464do: >34081212doLayoutIn: >34080432fullBounds >34080340on:do: >34080208fullBounds >34080116dispatchDefault:with: >34080024dispatchEvent:with: >34079916processEvent:using: >34079704processEvent:using: >34079612processEvent: >34079476sendEvent:focus:clear: >34079316sendMouseEvent: >34079224handleEvent: >34078552processMouseOver: >34078460processEvents >34078344doOneCycleNowFor: >34078228do: >34078136handsDo: >34078036doOneCycleNowFor: >34074316doOneCycleFor: >34074224doOneCycle >34074132spawnNewProcess >34073776newProcess Noah
