From 3fa5f1fa0a4973c6915fbfe0a43cbbe57c9b8ca9 Mon Sep 17 00:00:00 2001 From: Roland McGrath Date: Fri, 15 Nov 2002 03:36:52 +0000 Subject: [PATCH] 2002-11-14 Roland McGrath * sysdeps/generic/errno.c (__libc_errno): Remove alias. * inet/herrno.c (__libc_h_errno): Likewise. * resolv/res_libc.c (__libc_res): Likewise. [USE___THREAD]: Use this in place of [USE_TLS && HAVE___THREAD]. (__res_state) [! USE___THREAD]: Don't define as weak. * csu/Versions: Revert last change. * resolv/Versions: Revert last change. --- csu/Versions | 4 ---- inet/herrno.c | 3 --- resolv/Versions | 4 ---- resolv/res_libc.c | 15 +++++---------- sysdeps/generic/errno.c | 3 --- 5 files changed, 5 insertions(+), 24 deletions(-) diff --git a/csu/Versions b/csu/Versions index bd82a96149..a1321a9df8 100644 --- a/csu/Versions +++ b/csu/Versions @@ -21,10 +21,6 @@ libc { %if USE_TLS && HAVE___THREAD # This version is for the TLS symbol, GLIBC_2.0 is the old object symbol. errno; -%else - # This internal alias is solely to give libpthread access - # to the variable that is not directly user-visible at link time. - __libc_errno; %endif } } diff --git a/inet/herrno.c b/inet/herrno.c index f0ee81b804..b85d75be53 100644 --- a/inet/herrno.c +++ b/inet/herrno.c @@ -34,9 +34,6 @@ extern __thread int __libc_h_errno __attribute__ ((alias ("h_errno"))) int h_errno = 0; weak_alias (h_errno, _h_errno) -/* This alias is needed by libpthread. */ -strong_alias (h_errno, __libc_h_errno) - /* We declare these with compat_symbol so that they are not visible at link time.
