rub-syssec / jit-picker Goto Github PK

according to V8Profile, it alway wrap generated program in followed template :

function main() {
const fhash = fuzzilli_hash;
...
gc();
}
%NeverOptimizeFunction(main);
main();

May I ask why you do this? this looks no different than executing it directly in script file

$ swift build
error: missing LinuxMain.swift file in the Tests directory

I got something like this when building the project. My swift version is:

$ swift --version
Swift version 5.0.2 (swift-5.0.2-RELEASE)
Target: x86_64-unknown-linux-gnu

Could you please help to fix this issue? thanks a lot!

While applying JIT-Picker to v8 engine, I see that when we use a built-in or native function fuzzilli_hash to calculate hash of a variable inside an optimized function, the engine will bailout of optimization due to code dependency

Is it intended behavior? Or do we need to implement a transparent probe function like your paper mentioned for SpiderMonkey engine?

I notice that: JitPicker is already lagging far behind Fuzzilli, and last merge request have been closed.
So I wodner will JitPicker be merged into Fuzzilli in the future?
