Update.
2003-01-27 Martin Schwidefsky <schwidefsky@de.ibm.com> * elf/elf.h: Add new s390 relocs. * elf/tls-macros.h: Add s390 versions. * sysdeps/s390/Versions [GLIBC_2.3] (ld): Export __tls_get_offset. * sysdeps/s390/dl-tls.h: New file. * sysdeps/s390/libc-tls.c: New file. * sysdeps/s390/s390-32/dl-machine.h (elf_machine_type_class): Add TLS relocs for class PLT. (elf_machine_rela): Handle TLS relocs. * sysdeps/s390/s390-64/dl-machine.h: Likewise. * sysdeps/s390/s390-32/elf/configure.in: Add TLS check. * sysdeps/s390/s390-64/elf/configure.in: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/clone.S: Add support for CLONE_CHILD_*TID flags. * sysdeps/unix/sysv/linux/s390/s390-64/clone.S: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/mmap.S: Use branch with 32 bit offset. * sysdeps/unix/sysv/linux/s390/s390-64/socket.S: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/syscall.S: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.S (__syscall_error): Support USE___THREAD. Define RTLD_PRIVATE_ERRNO variant. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.S (__syscall_error): Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/sysdep.h: (SYSCALL_ERROR_LABEL): Move define next to SYSCALL_ERROR_HANDLER. (SYSCALL_ERROR_HANDLER): Add USE___THREAD and RTLD_PRIVATE_ERRNO variants. * sysdeps/unix/sysv/linux/s390/s390-64/sysdep.h: (SYSCALL_ERROR_LABEL): Move define next to SYSCALL_ERROR_HANDLER. Use direct branch to syscall_error for !PIC and PIC && !_LIBC_REENTRANT. (SYSCALL_ERROR_HANDLER): Add USE___THREAD and RTLD_PRIVATE_ERRNO variants.
