A compiler cannot run on bare metal. You need a GCC cross compiler to be able to do something like gcc -c -march=armv7 foo.adb on the host machine. > People can then use the compiler to write > code which runs on their specific board of interest. I don't think that would be very difficult, but, as I said in this discussion already, I would be quite useless unless you say what of the RTL goes over the board and what stays. -- Regards, Dmitry A.
