Update.
2003-01-17 Richard Henderson <rth@redhat.com> * sysdeps/alpha/dl-machine.h (elf_machine_type_class): Add TLS relocs for class PLT. * sysdeps/alpha/libc-tls.c: New file. * sysdeps/unix/alpha/sysdep.S (EPILOGUE, GPSAVEREG): New. (LOADGP) [!PIC]: Rewrite to preserve caller's gp. 2003-01-17 Jakub Jelinek <jakub@redhat.com> * sysdeps/unix/sysv/linux/ia64/dl-static.c (_dl_static_init): Use __libc_lock_{,un}lock_recursive instead of __libc_lock_{,un}lock on _dl_static_lock.
