From 661462d58f90c03765a8799714a9ea485d3b1935 Mon Sep 17 00:00:00 2001 From: "H.J. Lu" Date: Thu, 15 Oct 2015 14:22:10 -0700 Subject: [PATCH] Mark internal setjmp functions hidden Since internal dirent functions are only used internally in ld.so and libc.so, they can be made hidden. [BZ #19122] * include/setjmp.h (__longjmp): Add attribute_hidden.
