From de071d199a8578055edf2722114788ae749823aa Mon Sep 17 00:00:00 2001 From: Joseph Myers Date: Fri, 11 Sep 2015 20:00:19 +0000 Subject: Move bits/atomic.h to atomic-machine.h (bug 14912). It was noted in that the bits/*.h naming scheme should only be used for installed headers. This patch renames bits/atomic.h to atomic-machine.h to follow that convention. This is the only change in this series that needs to change the filename rather than simply removing a directory level (because both atomic.h and bits/atomic.h exist at present). Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch).
