[PATCH] i386: Hide __old_readdir64 [BZ #18822]
- From: "H.J. Lu" <hjl dot tools at gmail dot com>
- To: GNU C Library <libc-alpha at sourceware dot org>

- Subject: [PATCH] i386: Hide __old_readdir64 [BZ #18822]
- Authentication-results: sourceware.org; auth=none
Hide internal __old_readdir64 function to allow direct access within
libc.so and libc.a without using GOT nor PLT.
I will check it in after testing on i686.
H.J.
