From e67330ab57bfd0f964539576ae7dcc658c456724 Mon Sep 17 00:00:00 2001 From: Florian Weimer Date: Thu, 4 Aug 2016 11:10:57 +0200 Subject: [PATCH] x86: Use sysdep.o from libc.a in static libraries Static libraries can use the sysdep.o copy in libc.a without a performance penalty. This results in a visible difference if libpthread.a is relinked into a single object file (which is needed to support libraries which check for the presence of certain symbols to enable threading support, which generally fails with static linking unless libpthread.a is relinked). --- ChangeLog | 7 +++++++ sysdeps/unix/sysv/linux/i386/Makefile | 2 ++ 2 files changed, 9 insertions(+) diff --git a/ChangeLog b/ChangeLog index 0fe7eafe99..d88654cb06 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,10 @@ +2016-08-04 Florian Weimer + + Use sysdep.o from libc.a in static libraries. + * sysdeps/unix/sysv/linux/i386/Makefile + (libpthread-shared-only-routines): Add sysdep. + (librt-shared-only-routines): Likewise. + 2016-08-03 Joseph Myers * math/tgmath.h (nextdown): Define if diff --git a/sysdeps/unix/sysv/linux/i386/Makefile b/sysdeps/unix/sysv/linux/i386/Makefile index 71ba61e9d7..b015ff7c76 100644 --- a/sysdeps/unix/sysv/linux/i386/Makefile +++ b/sysdeps/unix/sysv/linux/i386/Makefile @@ -48,9 +48,11 @@ endif ifeq ($(subdir),nptl) # pull in __syscall_error routine libpthread-routines += sysdep +libpthread-shared-only-routines += sysdep endif ifeq ($(subdir),rt) # pull in __syscall_error routine librt-routines += sysdep +librt-shared-only-routines += sysdep endif
