Updates

• 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 trees and the numbers are much better (upto 4x improvement in some cases). They will submit this patch as well.
