OK, lets see how I like the idea of keeping diary. Yesterday has passed by studying for exams, today I should as well, but again I am not :) I've looked at RTH's thread local implemetnation. It looks usefull to get lower overhead for Zdenek's thread safe profiling patch, but still the patch has large overhead (for mozilla that can be about 8MB per thread, nasty). Perhaps I can copy the data on demand, but that does increase the overhead. I will send email about that. RTH didn't reviewed the tracer patch yet, so I probably won't prepare new ones. Andreas will benchmark the third liveness pass. It is badly needed, but it will hurt performance, since our liveness pass is lame. Perhaps time to rewrite it properly using bitmaps and daniels dataflow routines.
