Together with Jan Sjodin (in copy of this email), we begin an implementation of the JIT with MC. The idea, suggested by Jan, is to develop a MCJIT in parallel of the current JIT and to keep the two implementations until (at least) the new MC one is mature enough. Currently code is kept on gitorious (http://gitorious.org/llvm-mc-jit/llvm-mc-jit). Following this, a boolean "bool MCJIT =

Thanks for the patch! I'll clean this up, convert your sample to a unit test, and commit it for 2.7.

Hi LLVM folks, Attached with this email, you will find a patch not directly applicable (it doesn't compile like this) which (try to) enhance the structure of a possible JIT with the MC framework. Basically : - MCJIT : - Main class implementing ExecutionEngine interface - owns and creates : - a MemoryManager (will be a reuse of the JITMemoryManager mechanism) - a MCJITStreamer
