'''Moh (Vtune)'''
== Meeting Discussion Notes ==
* code now works fine despite short period of being broken
=== Status Updates ===
* uploaded installation and configuration guide on wiki
* is there an area of performance where we'd like Moh's team to focus? 
** edwin: interpreter
** ACTION: Moh will look into some hot loops (not readu30) and provide additional information
*** is this loop related to double-byte characters not being processed efficiently? Steven would need more details to confirm.


'''Marsha'''
Jeff:
* there are other performance tools available. could other tools be useful?
* Checked in a verifier refactoring. Some cleanup needed, but wanted to get it in.  
** we're most interested in tuning the interpreter and the generated code.
* Put in a pipeline architecture where all code generators are driven off of api (similar to backend nanojit api)
** speed is a bigger issue than memory footprint for the interpreter
** what are the upper bounds of footprint?  we are targeting:
*** memory: 128K RAM
*** code: 100K


'''Edwin (Tamarin-tracing)'''
* Steven is continuing to work on bugs
* Edwin is working on tracetree algorithm, which uses interpreter.cpp
* There has been a lot of work on the spec, which is part of why there hasn't been a lot of development recently.


'''Grayden'''
Steven
* posted updates to mini-tracing patch
* Spot bug fixing
** still slightly crashy but can run about half of the sunspider cases now -- getting better!
* ACTION: Edwin will add an updated tracetree patch to bugzilla later this week (txt patch is fine)
* Steven suggests rebuilding with superwords turned off; this might inprove things.
