#2Hm. Cool work, but I'm not sure I really see a practical use case? Ideas welcome.

#3How much faster/slower is it than aot code? I'm disapointed to see no benchmarks.

#4Polyglotting and being able to run it on any platform is pretty cool

#5A few potential use cases:
- Compile once, run anywhere for low-level languages like C++. With limitations, of course.
- More debugging capabilities. Maybe it could be used for dynamic analysis. Theoretically it should be possible to change code at runtime.
- Something like Valgrind? Valgrind is really complex and doesn't run on Windows at all. It seems like you could make a portable substitute with this.
- Maybe GraalVM can be used to provide additional memory safety guarantees, not sure.
Kind of hard for me to say because I don't actually know exactly what GraalVM provides, so it's kind of a guess. But it does seem like there are some genuine use cases beyond the neatness of it.

It's in the papers. About 20% slower.
The main use case seems to be speed up dynamic languages (ruby, python, javascript, R), and Sulong is used to handle the C extensions, so that the optimizations can be performed across the language boundaries. Unboxing and inlining mostly in the hot paths. Makes sense. Plus more memory safety than C/C++/Fortran.

For example I use it to run Ruby's C extensions on the JVM.

I believe that one compelling use case is to avoid the overhead of cross language boundaries (ie JNI) when the native code is compiled to bitcode and run with Sulong.

#9I wonder if it would be possible to run other languages such as rust, d, or ante, that use llvm, on this? Specifically interested in how languages with gc like d or nim will fare.

I wonder if that's the point. I'm not sure, I was just making guesses myself since it doesn't seem the motivation is stated.
