From 41e673c1e771075f413f8e8ecd9e108f5ae096d9 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Mon, 21 Aug 2017 05:58:39 -0700 Subject: x86-64: Mark internal symbols with attribute_hidden [BZ #18822] Since __syscall_clock_gettime and __start_context are internal symbols for Linux/x86-64, mark them with attribute_hidden. [BZ #18822] * sysdeps/unix/sysv/linux/x86_64/init-first.c (__syscall_clock_gettime): Add attribute_hidden. * sysdeps/unix/sysv/linux/x86_64/makecontext.c (__start_context): Likewise. --- ChangeLog | 8 ++++++++ sysdeps/unix/sysv/linux/x86_64/init-first.c | 2 +- sysdeps/unix/sysv/linux/x86_64/makecontext.c | 2 +- 3 files changed, 10 insertions(+), 2 deletions(-) diff --git a/ChangeLog b/ChangeLog index 8ff2d90bae..620bf81f83 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,11 @@ +2017-08-21 H.J.
