Very impressive (as is LuaJIT 1.x btw - works charmingly).
The LuaJIT 2.x VM operates in four phases:
I have a question for you about this.
There are many cases where I need to call a Lua function from C in a
very tight loop. The function is often simple, i.e. "function (r)
return r.a > 12 end". Do you expect LuaJIT to be able to optimize
this well when called a large number of times in succession? It would
be grand if this ends up becoming an int comparison (guarded by a
check, of course). Let me add that "r" is a userdata object, not a
table.
Will be doing timing tests later, just wondered how well this scenario
fits your model.
Thanks for describing your LuaJIT 2.x plans and good luck with getting
there.
