* Congratulations on TraceMonkey!
 
* (Andreas)
** Need to merge TM changes back to TT so that we can get back to one branch
** Potential review issues. There may be a couple of things that need work on the interpreter side.
** Peer fragments are a new concept to nanojit (probably not a lot of overhead)
** Andreas to package up reviews in separate packages to make it easier
 
* (Ed)
** Adobe has two changes
*** page allocations (big change)
*** Rick to review page allocations patch
*** bug in expression filter
***  Ed will wait to update until after Andreas stuff has landed.
***  Ed won't be able to land his changes this week, but they only need review. He will make his changes available for Andreas to review.
** Parallel ARM work needs to be coordinated as well. This needs to be coordinated with Rob Winchell. We need Rob's status and get his patches in a user directory or attached to a bug.
** Vtune patch for TT - ball is in Adobe's court to review it. Any updates needed to get it working with nanojit will be done by Adobe as well.
** Ed also has a validator on his side branch and he will queue that up as well.
 
* (Moh)
** Patch for parallel JIT'ing. Jung woo finished it for 3 and the numbers are much better (4x improvement). They will submit this patch as well.

== Updates ==
*(David)
**Explicit memory allocation
***Just made a quick patch on this.  This has also been discussed in previous meetings.  Plan is to commit the patch by next week.
*(Mason)
**Progress on x86 Forth representation.
*** Trying to get rid of the interpreter dispatch loop.  Has a basic version up now with 20% increase in speed in TT.  Hopes to have more test results by end of week.
*(Moh)
**Update on Jungwoo's results with parallel JITing in TT.
***Jungwoo has working now in TT. More work still needs to be done.
***Core-2 Duo is dual core, Silverthorne (Atom) is hyper-threaded.
**vprof is in TT. You can use it for value profiling. Extensions and more capabilities are underway.
***Ed has also ported this to alternative platforms. Ed also worked on a timer to help see transitions for various components.  Moh has also worked on some of the timers.
**Improving InlineHashTable. Good speedup observed on Win32. https://bugzilla.mozilla.org/show_bug.cgi?id=449886
***Looking at 64bitHashTable as well.
*(Steven)
**Taking fixes from Flash Player / TC and getting these integrated into the mainline.  May have to submit as multiple patches depending on how the check-in goes.
*(Ed)
**Will be doing reviews of the reviews: VTune patch, etc.  Thanks to those who put those in while he was out.
*(Mark)
**Waiting to hear on GlobalObjects issue with TC- any progress?  Someone on Adobe side is looking into this (Tom Harwood), but might take a bit of time to review.
