Update.
2003-01-11 Jim Meyering <jim@meyering.net>
* io/ftw.c [HAVE_CONFIG_H]: Include <config.h>.
[HAVE_SYS_PARAM_H || _LIBC]: Guard inclusion of <sys/param.h>.
Include <sys/stat.h>, not <include/sys/stat.h>, if !_LIBC.
[!_LIBC] (__chdir, __closedir, __fchdir, __getcwd, __opendir): Define.
[!_LIBC] (__readdir64, __tdestroy, __tfind, __tsearch): Define.
[!_LIBC] (internal_function, dirent64, MAX): Define.
(__set_errno): Define if not already defined.
(open_dir_stream): When FTW_CHDIR is enabled, invoke opendir on
the basename, not the entire file name.
(process_entry): When FTW_CHDIR is enabled, invoke XSTAT or LXSTAT on
the basename, not the entire file name.
2003-01-12 Ulrich Drepper <drepper@redhat.com>
* string/tester.c (test_strcpy): Disable last added strcpy until
it is fixed.
2003-01-11 Philip Blundell <philb@gnu.org>
* sysdeps/unix/sysv/linux/arm/socket.S: Add cancellation support.
2003-01-11 Andreas Schwab <schwab@suse.de>
* Makerules: Add vpath for %.dynsym and %.so so that the
implicit rule chaining for check-abi works.
2003-01-11 Kaz Kojima <kkojima@rr.iij4u.or.jp>
* sysdeps/unix/sysv/linux/sh/sysdep.h (SYSCALL_ERROR_HANDLER):
Add non-PIC case.
2003-01-11 Jakub Jelinek <jakub@redhat.com>
* elf/tls-macros.h [__ia64__] (__TLS_CALL_CLOBBERS): Define.
[__ia64__] (TLS_LE, TLS_IE): Fix typos. Add ;; at start of asm if
gp is used early.
[__ia64__] (TLS_LD, TLS_GD): Likewise. Use __TLS_CALL_CLOBBERS.
* elf/Makefile ($(objpfx)tst-tlsmod5.so, $(objpfx)tst-tlsmod6.so):
Ensure libc.so in DT_NEEDED.
* sysdeps/alpha/dl-machine.h (elf_machine_rela): Move
CHECK_STATIC_TLS before l_tls_offset use.
* sysdeps/i386/dl-machine.h (elf_machine_rel, elf_machine_rela):
Likewise.
* sysdeps/sh/dl-machine.h (elf_machine_rela): Likewise.
* sysdeps/generic/dl-tls.c (_dl_allocate_tls_storage) [TLS_DTV_AT_TP]:
Allocate TLS_PRE_TCB_SIZE bytes below result.
(_dl_deallocate_tls) [TLS_DTV_AT_TP]: Adjust before freeing.
* sysdeps/generic/libc-tls.c (__libc_setup_tls): If
TLS_INIT_TP_EXPENSIVE is not defined, allocate even if no PT_TLS
segment has been found. If TLS_DTV_AT_TP, allocate TLS_PRE_TCB_SIZE
bytes below result and add tcb_offset to memsz.
* sysdeps/ia64/dl-tls.h (__tls_get_addr): New prototype.
* sysdeps/ia64/dl-machine.h: Include tls.h.
(elf_machine_type_class): Return ELF_RTYPE_CLASS_PLT for TLS relocs
too.
(elf_machine_rela): Assume if sym_map != NULL sym is non-NULL too.
Handle R_IA64_DTPMOD*, R_IA64_DTPREL* and R_IA64_TPREL* relocations.
* sysdeps/ia64/libc-tls.c: New file.

redefinition of elf_fpreg_t and elf_fpregset_t.
2003-01-12 Ulrich Drepper <drepper@redhat.com>
* elf/dl-close.c (_dl_close): Add several asserts. Correct and
simplify test for unloading. If loader of a DSO is unloaded do not
use its scope anymore. Fall back to own scope and adjust opencounts.
Fix several comments.
* elf/dl-deps.c (_dl_map_object_deps): Always allocate memory for
the l_searchlist, not only for l_initfini.
* elf/dl-lookup.c (add_dependencies): Avoid creating relocation
dependencies if objects cannot be removed. Remove object with the

Update.
2003-01-11 Jim Meyering <jim@meyering.net>
* io/ftw.c [HAVE_CONFIG_H]: Include <config.h>.
[HAVE_SYS_PARAM_H || _LIBC]: Guard inclusion of <sys/param.h>.
Include <sys/stat.h>, not <include/sys/stat.h>, if !_LIBC.
[!_LIBC] (__chdir, __closedir, __fchdir, __getcwd, __opendir): Define.
[!_LIBC] (__readdir64, __tdestroy, __tfind, __tsearch): Define.
[!_LIBC] (internal_function, dirent64, MAX): Define.
(__set_errno): Define if not already defined.
(open_dir_stream): When FTW_CHDIR is enabled, invoke opendir on
the basename, not the entire file name.
(process_entry): When FTW_CHDIR is enabled, invoke XSTAT or LXSTAT on
the basename, not the entire file name.
2003-01-12 Ulrich Drepper <drepper@redhat.com>
* string/tester.c (test_strcpy): Disable last added strcpy until
it is fixed.
2003-01-11 Philip Blundell <philb@gnu.org>
* sysdeps/unix/sysv/linux/arm/socket.S: Add cancellation support.
2003-01-11 Andreas Schwab <schwab@suse.de>

[__ia64__] (TLS_LE, TLS_IE): Fix typos. Add ;; at start of asm if
gp is used early.
[__ia64__] (TLS_LD, TLS_GD): Likewise. Use __TLS_CALL_CLOBBERS.
* elf/Makefile ($(objpfx)tst-tlsmod5.so, $(objpfx)tst-tlsmod6.so):
Ensure libc.so in DT_NEEDED.

* sysdeps/generic/libc-tls.c (__libc_setup_tls): If
TLS_INIT_TP_EXPENSIVE is not defined, allocate even if no PT_TLS
segment has been found. If TLS_DTV_AT_TP, allocate TLS_PRE_TCB_SIZE
bytes below result and add tcb_offset to memsz.
