From fd331b1179df7fef8016273fb26f5f054793875a Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Sun, 1 Oct 2017 17:43:13 -0700 Subject: Hide internal __sched_setparam function [BZ #18822] Hide internal __sched_setparam function to allow direct access within libc.so and libc.a without using GOT nor PLT. __GI___sched_setparam is defined when sysdeps/unix/syscalls.list is used to generate sched_setparam. Otherwise libc_hidden_def is needed explicitly.
