From 15306e38888f770e548538a956e279b019654443 Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 15 Oct 2015 23:59:54 +0000 Subject: [PATCH] Remove NPTL configure errors based on top-level configure tests. sysdeps/nptl/configure.ac has code to give errors if certain tests in the top-level configure failed. However, all those failure conditions also produce errors in the top-level configure, so the errors in the NPTL configure are completely redundant; this patch removes them. (As suggested in , I think the top-level tests in question can be completely removed as unnecessary given the version tests. But even without that there is clearly no point in duplicating code that gives an error if the test fails.) Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * sysdeps/nptl/configure.ac: Do not give errors based on the results of top-level configure tests. * sysdeps/nptl/configure: Regenerated. --- ChangeLog | 4 ++++ sysdeps/nptl/configure | 9 --------- sysdeps/nptl/configure.ac | 9 --------- 3 files changed, 4 insertions(+), 18 deletions(-) diff --git a/ChangeLog b/ChangeLog index 652fa5a9e6..ad3f64f9e4 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,9 @@ 2015-10-15 Joseph Myers + * sysdeps/nptl/configure.ac: Do not give errors based on the + results of top-level configure tests. + * sysdeps/nptl/configure: Regenerated. + * configure.ac (libc_cv_Bgroup): Remove configure test. * configure: Regenerated. * config.make.in (have-Bgroup): Remove variable. diff --git a/sysdeps/nptl/configure b/sysdeps/nptl/configure index cce07b35d2..18bae6bbc0 100644 --- a/sysdeps/nptl/configure +++ b/sysdeps/nptl/configure @@ -1,14 +1,5 @@ # This file is generated from configure.ac by Autoconf.
