--- Comment #19 from Francesco Zappa Nardelli <francesco.zappa.nardelli at gmail dot com> --- >> does not perform the volatile load access. > It does starting with GCC 4.8.2 and was a bug in older GCC versions. I just tested my example (comment 16) against yesterday trunk gcc version 4.9.0 20130912 (experimental) (GCC) and indeed the volatile load access is no longer removed. This is a good news. However the code I reported in bug 58409, which has been marked duplicate of this bug, still exhibits the incorrect reordering of volatile accesses. It thus seems to me that either bug 58409 is not a duplicate of this one, or the fix is incomplete. -francesco
