LLVMdev Digest, Vol 132, Issue 104

Dave and others on the list
    Due to the design of OS-9 for 68K and other CPU's. compiling to a ROF format will probably not work. While we try to use the CPU Standard calling interface there are some OS-9 specific differences. The compiler ( Ultra-C) currently has an older EDG ( Edison Design Group) front end. Unfortunately the previous owner of the IP did not keep up the EDG support. The compiler does have an intermediate language named I-code. It is somewhat higher level than LLVM IR code. I can provide documentation under NDA if someone wants to take a serious look at this project. I-code is not processor specific.
