Update.
2003-01-14 Guido Guenther <agx@sigxcpu.org> * sysdeps/unix/sysv/linux/mips/sysdep.h (INTERNAL_SYSCALL, INTERNAL_SYSCALL_DECL, INTERNAL_SYSCALL_ERRNO, INTERNAL_SYSCALL_ERROR_P, INLINE_SYSCALL): Define. 2003-01-14 Steven Munroe <sjmunroe@us.ibm.com> * sysdeps/unix/sysv/linux/powerpc/powerpc64/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/powerpc64/vfork.S: New file. Patch by Denis Zaitsev <zzz@cd-club.ru>. that %eax is modified. Reported by Denis Zaitsev <zzz@cd-club.ru>.
