Some boring style comments: - whack trailing whitespace - spaces, not tabs - the methods in MCJITStreamer.cpp should probably have blank lines between them There seems to be an ownership problem of the MCJITObjectWriter. If I understand the code correctly, the assembler Finish method takes ownership of the Writer parameter, which presumably is needed to JIT two functions. +1 for separate patches, or alternatively, can we just commit this and begin developing this in-tree? Then other people can hack on it before...

...,b) => a+b), to do that some modifications have been made : - The addPassesToEmitMC method has been added to TargetMachine class. It fills the MCContext pointer so we can build the MCJITStreamer. - The Finish method of MCAssembler have a new optional argument "Writer" to allow a custom MCJITObjectWriter to be used. Can you give us some feedbacks on the general idea and on this 2 particular hooks ? Currently MCJIT has one unittest and the binary size is quite big (~110MB in debug...) because before using the MC framework we need to call "InitializeAllTargets()" and friends (same as llc...

...er about the address > of some external symbols though. OK, I'm still experimenting with this. But it seems that I just need to modify the "FixedValue" parameter of the RecordRelocation method. More on this in future patches. :) > There seems to be an ownership problem of the MCJITObjectWriter.

Ok, it's not really clear, but with the patch : - If no Writer is provided to the Finish method, the MCAssembler takes owne...
