[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.
