From 3d0dbdc46710c262bf4fc4786b32d61bd777b33b Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Thu, 15 Oct 2015 23:30:42 +0000 Subject: Remove sizeof (long double) configure test. There is a configure test for sizeof (long double) whose results aren't used anywhere. This patch removes that test. Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (sizeof_long_double): Remove configure test. * configure: Regenerated. * config.make.in (sizeof-long-double): Remove variable. --- ChangeLog | 4 + config.make.in | 2 - configure | 267 +-------------------------------------------------------- configure.ac | 5 -- 4 files changed, 5 insertions(+), 273 deletions(-) diff --git a/ChangeLog b/ChangeLog index e91c7e7..40e9897 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,5 +1,9 @@ 2015-10-15 Joseph Myers + * configure.ac (sizeof_long_double): Remove configure test. + * configure: Regenerated. + * config.make.in (sizeof-long-double): Remove variable. + * configure.ac (libc_cv_gcc_exceptions): Remove configure test. * configure: Regenerated. * sysdeps/arm/configure.ac (libc_cv_gcc_exceptions): Do not set diff --git a/config.make.in b/config.make.in index a7d4662..b376a7e 100644 --- a/config.make.in +++ b/config.make.in @@ -74,8 +74,6 @@ multi-arch = @multi_arch@ mach-interface-list = @mach_interface_list@ -sizeof-long-double = @sizeof_long_double@ - nss-crypt = @libc_cv_nss_crypt@ # Configuration options. diff --git a/configure b/configure index 81d003c..09e8ade 100755 --- a/configure +++ b/configure @@ -197,8 +197,7 @@ test -x / || exit 1" as_suggested=" as_lineno_1=";as_suggested=$as_suggested$LINENO;as_suggested=$as_suggested" as_lineno_1a=\$LINENO as_lineno_2=";as_suggested=$as_suggested$LINENO;as_suggested=$as_suggested" as_lineno_2a=\$LINENO eval 'test \"x\$as_lineno_1'\$as_run'\" != \"x\$as_lineno_2'\$as_run'\" && - test \"x\`expr \$as_lineno_1'\$as_run' + 1\`\" = \"x\$as_lineno_2'\$as_run'\"' || exit 1 -test \$(( 1 + 1 )) = 2 || exit 1" + test \"x\`expr \$as_lineno_1'\$as_run' + 1\`\" = \"x\$as_lineno_2'\$as_run'\"' || exit 1" if (eval "$as_required") 2>/dev/null; then : as_have_required=yes else @@ -587,7 +586,6 @@ PACKAGE_URL='http://www.gnu.org/software/glibc/' ac_unique_file="include/features.h" enable_option_checking=no -ac_includes_default='/* none */' ac_subst_vars='LTLIBOBJS LIBOBJS RELEASE @@ -616,7 +614,6 @@ libc_extra_cppflags libc_extra_cflags libc_cv_cxx_thread_local CPPUNDEFS -sizeof_long_double have_selinux have_libcap have_libaudit @@ -1727,231 +1724,6 @@ fi as_fn_set_status $ac_retval } # ac_fn_c_try_link - -# ac_fn_c_try_run LINENO -# ---------------------- -# Try to link conftest.$ac_ext, and return whether this succeeded.
