[llvm-dev] Execute / Interpret LLVM IR Bitcode
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.

In order to achieve what he needs we need a LLVM BC interpreter which simply doesn’t exist yet, and probably will never be. > > Zhang > >> 在 2018年8月29日，05:47，Stefan Gränitz via llvm-dev <llvm-dev at lists.llvm.org> 写道： >> >> Hi James >> >> I wanted to do something like this last year and found llvm-dbas, a hack >> of the LLVM assembler on GitHub.
