Update.

2004-07-05  Ulrich Drepper  <drepper@redhat.com>

	* elf/dl-init.c: Don't define and use _dl_starting_up if
	HAVE_INLINED_SYSCALLS is defined and the variable is not used.
	* elf/dl-support.c: Likewise.
	* elf/rtld.c: Likewise.
	* elf/dl-misc.c (_dl_debug_vdprintf): Use writev syscall directly
	if HAVE_INLINED_SYSCALLS is defined.
	* sysdeps/powerpc/powerpc64/dl-machine.h: Don't rest _dl_starting_up
	here.
	* sysdeps/powerpc/powerpc32/dl-start.S: Likewise.
	* sysdeps/unix/sysv/linux/configure.in: Define HAVE_INLINED_SYSCALLS.
	* config.h.in: Add entry for HAVE_INLINED_SYSCALLS.

	* sysdeps/posix/profil.c: If compiled for ld.so, omit code which
	is needed to stop profiling.
	* elf/dl-open.c (dl_open_worker): If a newly opened object is to be
	profile make sure it cannot be unloaded.

	* sysdeps/unix/sysv/linux/dl-origin.c: Inline readlink syscall.

	* sysdeps/unix/sysv/linux/fcntl.c: If compiled without cancellation
	support, make sure the helper function is inlined.
	* sysdeps/unix/sysv/linux/pread.c: Likewise.
	* sysdeps/unix/sysv/linux/pwrite.c: Likewise.
	* sysdeps/unix/sysv/linux/i386/fcntl.c: Likewise.
	* sysdeps/unix/sysv/linux/powerpc/powerpc64/fcntl.c: Likewise.
