* sysdeps/pthread/bits/libc-tsd.h: Include <tls.h>.
[USE_TLS && HAVE___THREAD]: Just include the sysdeps/generic file,
which does the right thing when __thread support is available.
* descr.h (struct _pthread_descr_struct) [USE_TLS && HAVE___THREAD]:
Omit `p_libc_specific', `p_errnop', `p_errno', `p_h_errnop',
`p_h_errno', `p_resp', and `p_res' members.
* pthread.c (__pthread_initialize_minimal) [USE_TLS && HAVE___THREAD]:
Don't initialize `p_errnop' and `p_h_errnop' members.
(__pthread_reset_main_thread): Likewise.
(__pthread_initialize_manager): Likewise.
* manager.c (__pthread_manager, pthread_handle_create): Likewise.
* pthread.c (pthread_initialize) [USE_TLS && HAVE___THREAD]:
Don't initialize `p_resp' member.
(__pthread_reset_main_thread): Likewise.
* manager.c (pthread_handle_create): Likewise.
* specific.c (libc_internal_tsd_set, libc_internal_tsd_get):
Conditionalize these on [!(USE_TLS && HAVE___THREAD)].
* errno.c [USE_TLS && HAVE___THREAD]
(__h_errno_location, __res_state): Don't define these at all.
* sysdeps/i386/tls.h (INSTALL_DTV): Add parens around arguments!
(INSTALL_NEW_DTV, GET_DTV): Likewise.
* sysdeps/sh/tls.h (INSTALL_DTV, INSTALL_NEW_DTV, GET_DTV): Likewise.
* weaks.c: Don't include <errno.h> here.
2002-08-01 Roland McGrath <roland@redhat.com>
* sysdeps/i386/tls.h (TLS_DO_MODIFY_LDT): New macro, broken out of
TLS_INIT_TP.
(TLS_DO_SET_THREAD_AREA): New macro, uses thread_set_area syscall.
(TLS_SETUP_GS_SEGMENT): New macro, try one or the other or both.
(TLS_INIT_TP): Use that.
