Hi guys,
I've written a simple AOT compiler [1] that takes a javascript file
and transform it to a .class file that can run with a very small
runtime. It uses the Nashorn Parser API and also Nashorn to bootstrap
itself (the AOT is written in JavaScript).
While the runtime is fairly naive, everything is considered as an
java.lang.Object and JS Objects are hash maps (each field is accessed
through a double indirection), I've found that Nashorn was really slow
to run the AOT script (jsjs.js) compared to using jsjs to compile
itself, given that some Nashorn stacktraces seems to show
recompilation on top of recompilation on ... etc, I think there is a
bug that lies somewhere in the runtime of Nashorn.
You can run Nashorn on jsjs.js that way:
jjs -J-Xbootclasspath/p:lib/nashorn.jar -cp
classes:lib/asm-debug-all-5.0.3.jar jsjs.js -- jsjs.js
and jsjs on jsjs.js that way:
java -Xbootclasspath/p:lib/nashorn.jar -cp
.:classes:lib/asm-debug-all-5.0.3.jar jsjs jsjs.js
cheers,
Rémi
