[Vm-dev] Pharo 7 on SqueakJS (demo)

[Bert Freudenberg]

Hi Pavel,

yes, I don't think the current JIT can get much faster. It improves
bytecode speed, but does nothing for sends, which is the more important
part.

I don't have much free time in the near future, but I have written up some
ideas for a better JIT:

https://github.com/bertfreudenberg/SqueakJS/wiki/JIT-Ideas

This is a wiki, feel free to edit / add.
