Re: [webkit-dev] DFG optimizations

2012-03-25 Thread Nare Karapetyan
HI! 

There is a discussion about LICM implementation in DFG in one of previous
posts.
There it was said that the developers had not decided yet which
optimization to do: LICM or loop peeling with global CSE.
So is there any progress in this direction?


And about CSE, does it include the partial redundancy elimination (PRE)?

[webkit-dev] DFG, inline functions compileing

2012-06-16 Thread Nare Karapetyan
Why in DFG inline functions are optimized(compiled) more than once - one
time itself and then in caller function's body?

If the object file is meant by a cfg IR dump, then yes.
Assume that all of repeated compilations are okay,
but then again going through all the passes of the optimizations
in caller function probably does not make sense.
Or I'm not right?

And I think You talk about JSC compiling, not about DFG JIT work.

[webkit-dev] DFG Idom relation

2012-08-06 Thread Nare Karapetyan
Hi. What are you thinking about building idom structure in DFGDominators?
I suggest add  idom relation(i.e. dominators tree), since that's much
used in global optimizations. Isn't it ? I can submit patch.
