Hi!
The following new test (tst-popen) got broken when vfork has been
made hidden in libc. linuxthreads really needs to use full-blown
fork if pthread_create has been ever called.
The following patch fixes this.
I've left cris, sh, arm, m68k and powerpc64 unchanged, they need
similar changes, otherwise tst-popen will fail.
s390, s390x and powerpc32 are using sysdeps/generic/vfork.c,
ie. they use fork no matter if vfork or fork is used.
Martin said he'll change s390*, Franz, could you look at why ppc32
doesn't use vfork? If vfork is added for these arches, it will
need special assembly in linuxthreads.
Tested on i386/i686/IA-64/x86-64/alpha/alphaev6/ppc32.
2003-01-09 Jakub Jelinek <jakub@redhat.com>
* posix/test-vfork.c (noop): Add __attribute_noinline__.
* sysdeps/generic/sysdep.h (JUMPTARGET): Define if not defined.
* sysdeps/i386/sysdep.h (JUMPTARGET): Undefine JUMPTARGET before
defining it.
