Add attribute_tls_model_ie. * include/netdb.h (h_errno): Define to __libc_h_errno in libc.so. Add attribute_tls_model_ie. * include/resolv.h (_res): Define to __libc_res in libc.so. Add attribute_tls_model_ie. * inet/herrno.c (__libc_h_errno): Add hidden alias to h_errno. (h_errno): Define. * resolv/res_libc.c (__libc_res): Add hidden alias to _res. (_res): Define. * sysdeps/generic/bits/libc-tsd.h (__libc_tsd_define): Add attribute_tls_model_ie. * sysdeps/generic/errno-loc.c (errno): Only undefine if not using __thread. * sysdeps/generic/errno.c (__libc_errno): Add hidden alias to errno. * sysdeps/unix/sysv/linux/i386/sysdep.h (SYSCALL_ERROR_HANDLER): Use __libc_errno in USE___THREAD case. * sysdeps/unix/sysv/linux/x86_64/sysdep.h (SYSCALL_ERROR_HANDLER): Likewise. * configure.in (HAVE_TLS_MODEL_ATTRIBUTE): Check for __attribute__((tls_model (""))). * configure: Rebuilt. * config.h.in (HAVE_TLS_MODEL_ATTRIBUTE): Add. --- resolv/res_libc.c | 3 +++ 1 file changed, 3 insertions(+) (limited to 'resolv') diff --git a/resolv/res_libc.c b/resolv/res_libc.c index 9f9af1d701..60f7febf05 100644 --- a/resolv/res_libc.c +++ b/resolv/res_libc.c @@ -27,6 +27,9 @@ #if USE_TLS && HAVE___THREAD /* With __thread support, this per-thread variable is used in all cases. */ __thread struct __res_state _res; +extern __thread struct __res_state __libc_res __attribute__ ((alias ("_res"))) + attribute_hidden; +# define _res __libc_res #else /* The resolver state for use by single-threaded programs. */ struct __res_state _res; -- cgit v1.2.3
