From 730bbab2c39dd615c31c924041b4d16d7f107ae0 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Wed, 6 Jan 2016 12:37:04 -0800 Subject: Mark internal unistd functions hidden in ld.so Since internal unistd functions are only used internally in ld.so and libc.so, they can be made hidden. __close, __getcwd, __getpid, __libc_read and __libc_write can't be hidden in ld.so on Hurd since they will be preempted by the ones in libc.so after bootstrap.
