Java bytecode to LLVM IR

[Xiangyang Guo]

Hi, All,

I want to convert Java bytecode to LLVM IR. After a quick search, it seems RoboVM has this function. But I don't know how to achieve this after reading the document. It seems that I need to modify the source code to do this. Could you tell me which part I need to focus on? Any hint is appreciable. Thanks

BTW, I just quickly scan the source code, it seems Soot is used in this project. But as far as I know, Soot has its own IR, so where is the IR converter? Thanks

You can force RoboVM to dump the LLVM IR code via the -dump-intermediates switch. This will place .ll files in your RoboVM cache.

The LLVM IR alone will however not help you to run Java code natively. You'll also need the VMy bits, such as a GC and the runtime. Look into MethodCompiler.java for (most of) the Soot -> IR translation.

Hi, Mario,

Thanks for your quick reply. It works. Thank you.

Hi Xiangyang,

i see you can dump IR with Robovm, so could you help me to resolve it. i can't use "robovm-compiler-*.jar" with Robovm. Robovm want to use "robovm-dist/compiler/target/robovm-dist-compiler*.jar".

Could tell me how to debug Robovm with my build out jar?

Thanks

Hello

 Could you tell me how can I download roboVM and run it on a linux machine in order to convert Java ByteCodes to LLVM IR

The LLVM IR produced by RoboVM is highly specific to RoboVM and I doubt it will be useful in any other context.
