How to generate a consistent iOS and Unix VM?
by Stefan Marr 22 Apr '11

22 Apr '11

Hi: I am a bit lost on what the current status with the whole SqueakVM story is today. Do I want the SVN code base, do I want the git repo (the later would be much much more convenient to keep in sync with you...)? What I would like to do is to generate a consistent code base for the VM (preferable the standard non-Cog non-Stack interpreter). My target platforms are iOS (MacOSX would be nice, but iPhone/iPad are the primary target) and Unix (MacOSX,Linux). My goal is to get all the RoarVM plugin code and the other stuff that is not related to the VM in sync with the Squeak VM. So, how do I do that? More precisely, which would be the right VMMaker version for the correct code repository version? I noticed that the SVN contains all the generated code for the iPhone, but it seems to be outdated and out of sync with the rest of the code base.

Dave Lewis uploaded a new version of VMMaker to project VM Maker: http://www.squeaksource.com/VMMaker/VMMaker-oscog-dtl.64.mcz ==================== Summary ==================== Name: VMMaker-oscog-dtl.64 Author: dtl Time: 21 April 2011, 8:24:32 am UUID: c1d30608-30ec-50b7-208a-31f7a46c1508 Ancestors: VMMaker-oscog-dtl.59 Re-save from VMMaker-oscog-EstebanLorenzano.62 because VMMaker-oscog-dtl.61 and VMMaker-oscog-dtl.60 were saved without correct ancestry. This version incorporates the changes from VMMaker-oscog-EstebanLorenzano.62, VMMaker-oscog-dtl.61, and VMMaker-oscog-dtl.60. Name: VMMaker-oscog-EstebanLorenzano.62 -added ClipboardExtendedPlugin as a regular plugin (taken from the InterpreterVM branch) I don't know if it works right now, but at least it compiles :) Name: VMMaker-oscog-dtl.61 A second batch of updates from VMM trunk, primarily cosmetic but also a class comment update and a couple of methods that had not previously been pragmatized in oscog. Name: VMMaker-oscog-dtl.60 These changes are methods from the main VMM branch for which <#var:#type:> declarations have been formatted with proper spacing. By updating these in the oscog branch, all of these methods are identical in both branches. All changes are cosmetic (no functional changes to the methods).

Balloon engine and bitmap fills: any clues why it ignores an alpha channel of bitmap?
by Igor Stasenko 21 Apr '11

21 Apr '11

I tried various paint rules 24, 34 nothing. A balloon engine seems like completely ignores an alpha channel, so i could use it for filling shapes using bitmaps as long as these bitmaps fully opaque. I thought i could use a generic way to render bitmaps, instead of using awkward warpBlt... but it seems like something in plugin discards/ignores an alpha channel of source bitmap. I would be happy if this is not true. -- Best regards, Igor Stasenko AKA sig.

>From can I can see with me newbie search in the VM, it is not used. splObj: 33 ObjectMemory class >> initializeSpecialObjectIndices TheInterruptSemaphore := 30. SelectorCannotInterpret := 34. it jumps from 30 to 34. I search places doing "splObj: 33" but I didn't find anything. Maybe the VM guys can confirm or reject this.

Updated the the Cog Google code and Gitorious home pages
by Mariano Martinez Peck 21 Apr '11

21 Apr '11

Hi guys. Cog info is a little spread in different places. I've just updated the home pages of: https://gitorious.org/cogvm http://code.google.com/p/cog/ I put all the interested links so that at least we can jump from one place to another other one. If you (Eliot?) feel more links or info should be put, please let me know. Best regards, -- Mariano http://marianopeck.wordpress.com

Compiler Optimization in the different CMakeConfigs
by Mariano Martinez Peck 21 Apr '11

21 Apr '11

Hi guys. Unix and Windows confs have -O2. However, in Mac, the Carbon ones have -O3 y the cocoa ones -Os. As far as I know -Os is for size, so we really don't care about that (unless we are in a mobile device). So, is there a reason why Unix and Windows use -O2 and Mac -O3 ? should we chage this? which should we use? Thanks in advance, -- Mariano http://marianopeck.wordpress.com
