You mean, let gcc generate n64 code, stuff it in n32 objects, and objcopy it back to n64? Well, it may work, but it looks more like a test of binutils sign-extension handling than a straightforward way of creating kernels to me. Besides, as soon as gcc handles 64bit expansions itself we need such an option anyway. Thiemo
