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.
