Hello everybody,
I am currently looking at the LLVM project to find if it is suitable for what I have in mind. My research consists in optimization of parallel applications (mainly MPI and OpenMP) via transformations. What I need is the possibility to analyze and optimize production programs written in C/C++ and Fortran.
So, I've been looking inside a lot of source-to-source compilers (like ROSE) but as far as it's a 100% research project, it is really not ready to be used with production code. 
On the other hand another approach could be use LLVM... and apply the transformations directly at bytecode level. This second way is quite interesting and gives me a lot of advantages (like the ability to take into account several languages)... but I need stronger program analysis.
It would nice if I could use LLVM bytecode with OpenAnalysis (http://openanalysis.berlios.de/). I know that some people worked on this aspect (LLVM - OA integration) but I cannot find anything on the internet about that. So I am asking to you... GURUs of the Low Level Virtual Machines... can you give me some pointers to this integration?
regards, Simone Pellegrini
