...mmutable pass, you can get the ModuleDecisionTreeProxies in every pass you need it by simply call "getAnalysis<ModuleDecisionTreeProxies>()" Thanks Hongbin PS: I attached our iterative driver, you could have a look if you are interested.

Radovan, Thanks for posting this! I would really like to have this kind of functionality available.

This is a first step towards to full iterative compilation framework for Clang/LLVM. The attached patch is work in progress and the idea of sending it to the list earlier rather than later is to open up a discussion on iterative compilation in Clang/LLVM. All comments are welcome, especially those related to integration of the framework into Clang/LLVM. Current compilers have pipeline structure
