That's it. I think it would assist in understanding Encoder subclasses and MethodNode>>#generate. Cheers, Chris

"The tragedy of PIC" summary
by stephane ducasse 02 Jul '13

02 Jul '13

Hi eliot So I was reading the PhD of Holzle and I wanted to know - I remember that at southampton (yes that far) you did a presentation on the tragedy of the PIC. And I would not find the slides (because there were none). What was the pitch? That megamorphic site are killing PIC? - does VW use type feedback? if yes, what were the strategies to decide what and when to recompile. - I was wondering how type feedback and PIC interact (I'm at chapter 5 of the PhD so may be this is explain in the self implementation part) the first case of the PIC could be based on type feedback?
