== Agenda Items Discussed ==
Jeff:
* Status of TC Release (Trevor Baker)
* Checked in a verifier refactoring. Some cleanup needed, but wanted to get it in.
* Power PC Status (Edwin Smith)
* Put in a pipeline architecture where all code generators are driven off of api (similar to backend nanojit api)
* X64 Update (Rick Reitmaier)
* Global Optimizer (Tom Harwood)
* Verifier (Jeff Dyer)


== Updates ==
=== Status of Tamarin Central Release (Trevor Baker) ===
* All acceptance tests passing - revision 703 of TC is stable
* Trevor to send changelist to list and post on other locations.
* Code size - 79 K bigger than VM in Flash 10
** Prior to merge from Redux, we had reduced by 85K
* Performance - faster across the board. Most dramatic improvement linux using interpreter flash player 10 up to 182% faster
* Memory usage
** mac using 8% less memory
** every other platform using more (worst is using forceMIR on Windows using about 22% more memory)
* ACTION for QE to be added to backlog: Need a measure relative to the flash 10 VM
* Release notes (detailing changelist) will be provided.


Steven
* Spot bug fixing


=== Power PC Status (Edwin)===
Dan Schaffer
* PPC Nanojit port, now at Beta quality, code here - [http://hg.mozilla.org/users/edwsmith_adobe.com/ppcjit]
* Ecma 3 data acceptance tests
* Tracking bug here: [https://bugzilla.mozilla.org/show_bug.cgi?id=458077]
* If anyone sees any failures, send Dan Schaffer an email
* Performance is decent, ranging from slightly slower to 25% faster on sunspider/* and misc/*.
* There may still be some lurking problems


=== X64 Update (Rick) ===
Tom Harwood
* Still working on build and it is starting to generate LIR updates
* Global optimizer stopped working on this for now
* Found a problem with LIR generation that is being tracked down
* Starting to work on verifier and code generators instead
* Jeff’s change broke GO code
* Tom filed a bug on that. Copy Jeff on that but.


=== Global Optmizer (Tom H) ===
* Now it can optimize and run most programs
* working on a deployment guide
* Performance - code size reduced by 15-20% (with standard deviation about the same)
* Still improving the code generated on the backend
* Will look at LVM integration and getting better error behavior
* GO will be posted on opensource.adobe.com (when it is in its final state)
=== Verifier (Jeff Dyer)===
* Will post notes to tamarin devel list and check into tamarin repository
* Need a doc directory in Tamarin (off of the root)
* Feel free to review doc when posted
* Will create a separate bug to track the verifier documentation
* Next step is to do some refactoring of the verifier to separate code generation and verification logic.
=== Compiler Issue with Sun Sparc (Brent) ===
* Brent will ping Leon (bug for Sun Studio compiler) to see if there is an update as to when the compiler will be fixed.
* current issue is to modify code to get around issues for sun studio compiler for  nanojit to work. Leon seemed to think it will be fixed in the sun compiler.
