I only see INTERNAL_SYSCALL on ARM, but perhaps I'm looking at an old version of uclibc? You have to test the result of clone() before calling _exit(). How do you guarantee the compiler inserts no memory writes in that sequence using just INTERNAL_SYSCALL on all architectures? -- Jamie _______________________________________________ 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
