[llvm-dev] Execute / Interpret LLVM IR Bitcode

[Jacob Kreindl via llvm-dev]

Hi all,

You could take a look at Sulong (1) for this. Sulong is an LLVM BC 
interpreter that also supports both IR-level and source-level debugging. 
The IR-level debugging feature described at (2) sounds very much like 
what James wants to have. Sulong is part of GraalVM (3) which provides 
builds for multiple platforms.


I apologize for not replying to the specific thread. I am working on 
Sulong rather than LLVM, so I only receive this mailing list as a digest 
to keep up with the latest developments of this project and usually 
don't participate in any discussions here.
