Re: [Pharo-dev] OpalCompiler evaluate speed

by monty

That's great, Marcus. Lots of code depends on the compiler for dynamic evaluation, including compilers that translate other languages to ST (like the XPath lib), so a faster compiler isn't insignificant. I know optimizing it takes time and probably isn't a high priority, but we could at least commit to not allowing it to get slower. For example, forget about replacing the RB parser with a PP-based one (which some have expressed interest in), since it looks like it would be slower, even with PP compiler: http://scg.unibe.ch/research/petitcompiler > Sent: Tuesday, February 13, 2018 at 12:04 PM > From: "Marcus Denker" <marcus.denker(a)inria.fr> > To: "Pharo Development List" <pharo-dev(a)lists.pharo.org> > Subject: Re: [Pharo-dev] OpalCompiler evaluate speed > > > > > On 24 Nov 2017, at 10:54, Marcus Denker <marcus.denker(a)inria.fr> wrote: > > > > > > > >> On 23 Nov 2017, at 23:37, ClÃ©ment Bera <bera.clement(a)gmail.com> wrote: > >> > >> Hi Nicolas. > >> > >> Just some comments: > >> > >> Another thing you can try is to remove the allocation of Opal's IR. It seems people use the IR only through the IRBuilder, so the API can be kept but it can generate directly bytecode instead of IR then bytecode. Removing those allocations would speed things up. It means merging IRFix / IRTranslator / IRBytecodeGenerator somehow and have the IRBuilder API directly call the new resulting merged class. > >> > >> Another thing is that when Opal became the default compiler, I evaluated the speed and saw it was slower, but when loading large projects it seemed loading time was dominated by Monticello / source reading / source loading and the compilation time was overall not that significant (< 20% of time). I don't know if this is still the case with GIT. I have problems currently when editing some large methods (it seems in the IDE the method is compiled at each keystroke...) and when doing OpalCompiler recompileAll (which I do often since I edit bytecode sets) but else the performance of Opal seems to be OK.

Would you be ready to explain ? I have started to write something about it (I need to make it clearer for myself, too). When it is in some presentable shape (currently just notes) I will forward it.
