Any thoughts on > that? So "spu64" would mean "spu + 64"? That makes it more difficult to read, and to grep. What about allowing multiple ABIs, separated by commas? So that line would become: 245 spu,64 clock_settime sys_clock_settime Gr{oetje,eeting}s, Geert -- Geert Uytterhoeven -- There's lots of Linux beyond ia32 -- geert@linux-m68k.org In personal conversations with technical people, I call myself a hacker.
