(INTERNAL_SYSCALL_DECL, INTERNAL_SYSCALL_ERRNO, INTERNAL_SYSCALL_ERROR_P): Adjust accordingly. (INLINE_SYSCALL): Make use of INTERNAL_SYSCALL. * sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S: New file. 2002-01-09 Richard Henderson * sysdeps/alpha/dl-machine.h (elf_machine_rela): Compute DTPREL64 and TPREL64 without loadbase applied. 2002-01-09 Richard Henderson * sysdeps/unix/alpha/sysdep.S: Use correct definition of errno for NOT_IN_libc. * sysdeps/unix/sysv/linux/alpha/sysdep.h: Move inline syscall bits... * sysdeps/unix/alpha/sysdep.h: ... here. (PSEUDO_LOADGP): Remove. (PSEUDO_PROLOGUE): Load GP in non-pic case. (SYSCALL_ERROR_LABEL): New. (PSEUDO): Use it in error branch. (PSEUDO_END): Add $syscall_error label. --- sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S | 56 +++++++++++++++++++++++ 1 file changed, 56 insertions(+) create mode 100644 sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S (limited to 'sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S') diff --git a/sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S b/sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S new file mode 100644 index 0000000000..9a0f53e99e --- /dev/null +++ b/sysdeps/unix/sysv/linux/powerpc/powerpc32/vfork.S @@ -0,0 +1,56 @@ +/* Copyright (C) 2003 Free Software Foundation, Inc. + This file is part of the GNU C Library. + + The GNU C Library is free software; you can redistribute it and/or + modify it under the terms of the GNU Lesser General Public + License as published by the Free Software Foundation; either + version 2.1 of the License, or (at your option) any later version. + + The GNU C Library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
