Hi, I am working on a new port. The arch is a 16 bit machine. The current state should enable any compilation. Libgcc is compiled. The cc1 is working. Now I try to validate. My method is to launch make check-gcc. But many tests go wrong for two main reasons: some tests need to include standard header files, but we do not need to implement a libc some tests are too long or use too large arrays and it is impossible with the memory of the machine Do you know better methods to validate GCC for such an arch? Should we implement a libc since there is no OS? Please, I need advice. Regards. Florent
