From 314ba75e4a26f7147c757a10b07a62ff113409aa Mon Sep 17 00:00:00 2001 From: Stefan Liebler Date: Fri, 7 Oct 2016 09:56:48 +0200 Subject: Use libc_ifunc macro for siglongjmp, longjmp in libpthread. This patch uses the libc_ifunc macro to create already existing ifunc functions longjmp_ifunc, siglongjmp_ifunc if HAVE_IFUNC is defined. The s390 pt-longjmp.c includes the common pt-longjmp.c and uses strong_alias to create the longjmp, siglongjmp symbols for glibc version 2.19. ChangeLog: * nptl/pt-longjmp.c (DEFINE_LONGJMP): Use libc_ifunc macro. * sysdeps/unix/sysv/linux/s390/pt-longjmp.c (longjmp, siglongjmp): Use strong_alias to create symbols for glibc verison 2.19. --- sysdeps/unix/sysv/linux/s390/pt-longjmp.c | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) (limited to 'sysdeps/unix/sysv/linux') diff --git a/sysdeps/unix/sysv/linux/s390/pt-longjmp.c b/sysdeps/unix/sysv/linux/s390/pt-longjmp.c index 10e825c..2abf112 100644 --- a/sysdeps/unix/sysv/linux/s390/pt-longjmp.c +++ b/sysdeps/unix/sysv/linux/s390/pt-longjmp.c @@ -26,8 +26,8 @@ /* In glibc release 2.19 new versions of longjmp-functions were introduced, but were reverted before 2.20.
