Ulrich Weigand c58fc258a2 cmake: Improve test for 16-byte atomic support on IBM Z ... Commit d1b9d14324 added a check for 16-byte atomics without library support on IBM Z. Unfortunately it turns out this test only works correctly when the test case is built without optimization. (This is normally true, but it may not be the case when passing explicit CXXFLAGS to cmake.) The underlying reason is that GCC may choose to use either an inline implementation of the 16-byte atomics or library calls, depending on whether or not it is able to prove the atomic variable is properly aligned. At -O0 it is never able to prove that, but at higher optimization levels it depends on the complexity of the expression (in particular, whether GCC can track down the definition of the underlying object). As the test case uses a very simple expression, it may happen that this test can be built without requiring library support, but some of the "real" uses of atomics in Ceph code cannot. This defeats the whole purpose of the test at configure time. Fixed by making the access pattern in the test more complex, so that the test fails even at high optimization levels.
