...e machines. This way, no system calls would be needed and everything would be with little memory usage. Obviously this could blow up the stack but it would be efficient in out use case. (Every coroutines pauses and returns to the scheduler, this scheduler then activates the next coroutine) Toralf Niebuhr [1]http://code.google.com/p/llvm-stack-switch/

Hi llvmdev! I've been working on adding coroutines to LLVM. Mentioned below is the implementation plan I'm following, for suggestions, flames and other input. Using segmented stacks is a prerequisite. The idea is to associate every coroutine with a coroutine descriptor. A coroutine descriptor consists of four words: w0, w1, w2 and w3. w0 always contains the _launcher_, and invoking a

Thanks for the reply. The LoopInfo pass can actually identify the loop I mentioned. My former question is due to a bug in my pass. What I worried is that LoopInfo can not identify all the natural loops for the benchmarks I use, but now I haven't found any such cases.
