Update.
2002-01-12 Franz Sirl <Franz.Sirl-kernel@lauterbach.com> * sysdeps/unix/sysv/linux/kernel-features.h (__ASSUME_VFORK_SYSCALL): Define for powerpc. * sysdeps/unix/sysv/linux/powerpc/syscall.S: Take register alignment into account. * sysdeps/unix/sysv/linux/powerpc/powerpc32/sysdep.h (INTERNAL_SYSCALL): Make use of ERR parameter. (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 <rth@redhat.com> * sysdeps/alpha/dl-machine.h (elf_machine_rela): Compute DTPREL64 and TPREL64 without loadbase applied. 2002-01-09 Richard Henderson <rth@redhat.com> * 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.
