I am writing the part of decompiling dex and apk. The current speed is about 10 times faster than that of Java, and it takes up less resources than Java. And the compiled binary is smaller, only about 300k. Thank you for your attention.

This has been my life experience with things written in C/C++, so speed doesn't matter. Or, I guess from an alternative perspective, it ran very fast, but exited very fast, too :-D

  $ ./objdir/garlic $the_jar_file -o out-dir -t $(nproc)

Sorry for giving you a bad experience. Please provide the jar file or class file. I hope I can fix it as soon as possible.

Is it? This is my experience with Python. The C/C++ programs I use daily never seem to crash (Linux, bash, terminals, X, firefox, vim, etc.). It must be years ago one of those programs crashed while I used it.

Also a segfault IS the protection layer intervening, it is equivalent to a exception in other languages. The real problem is, when there is no segfault.

This is absolutely true. But even this does not happen in the software I use every day. Software written is C is definitely the most stable I use - by far. That there are people running around claiming that it is impossible to write stable software in C and it crashes all the time due to bugs is rather unfortunate, as it is far from the truth.

> 10 times faster than that of Java

I was hoping that these days' Java would be "almost" as fast C/C++. Oh well.

In the process of writing this, I learned a lot about JVM. JVM has done well enough, even surpassing C/C++ in some cases.
