for some raw numbers: with my default FDPIC boot (inetd/syslog/watchdog), we icache flush 18,562,124 bytes. with this stack fix, we cut off 3,538,944 bytes (19% shrinkage). -mike _______________________________________________ uClinux-dev mailing list uClinux-dev@uclinux.org http://mailman.uclinux.org/mailman/listinfo/uclinux-dev This message was resent by uclinux-dev@uclinux.org To unsubscribe see: http://mailman.uclinux.org/mailman/options/uclinux-dev
