From b8fcdddcbb192fc367ff04bbd753b9deb69b09f3 Mon Sep 17 00:00:00 2001 From: Waldemar Brodkorb Date: Sat, 28 May 2016 18:12:58 +0200 Subject: nios2: sync support with glibc Only static linking is supported for now. More debugging and analyzing for ld.so, TLS and NPTL is required. But at least you can bootup a static root fileystem in Qemu. --- libc/sysdeps/linux/nios2/clone.c | 50 ---------------------------------------- 1 file changed, 50 deletions(-) delete mode 100644 libc/sysdeps/linux/nios2/clone.c (limited to 'libc/sysdeps/linux/nios2/clone.c') diff --git a/libc/sysdeps/linux/nios2/clone.c b/libc/sysdeps/linux/nios2/clone.c deleted file mode 100644 index eec9f42ff..000000000 --- a/libc/sysdeps/linux/nios2/clone.c +++ /dev/null @@ -1,50 +0,0 @@ -/* - * libc/sysdeps/linux/nios2/clone.c -- `clone' syscall for linux/nios2 - * Copyright (C) 2000-2006 Erik Andersen - * - * Licensed under the LGPL v2.1, see the file COPYING.LIB in this tarball. - * - * - * Copyright (C) 2004,05 Microtronix Datacom Ltd - * Copyright (C) 2002,03 NEC Electronics Corporation - * Copyright (C) 2002,03 Miles Bader - * - * Written by Miles Bader - * Nios2 port by Wentao Xu - */ - -#include -#include -#include - -int clone (int (*fn)(void *arg), void *child_stack, int flags, void *arg, ...) -{ - register unsigned long rval __asm__ ("r2") = -EINVAL; - - if (fn && child_stack) { - register unsigned long syscall __asm__ ("r3"); - register unsigned long arg0 __asm__ ("r4"); - register unsigned long arg1 __asm__ ("r5"); - - /* Clone this thread. */ - rval = TRAP_ID_SYSCALL; - syscall = __NR_clone; - arg0 = flags; - arg1 = (unsigned long)child_stack; - __asm__ __volatile__ ("trap " - : "=r" (rval), "=r" (syscall) - : "0" (rval),"1" (syscall), "r" (arg0), "r" (arg1) - ); - - if (rval == 0) { - /* In child thread, call fn and exit. */ - arg0 = (*fn) (arg); - syscall = __NR_exit; - __asm__ __volatile__ ("trap " - : "=r" (rval), "=r" (syscall) - : "1" (syscall), "r" (arg0)); - } - } - - __syscall_return (int, rval); -} -- cgit v1.2.3
