+          OptimizationRemark Remark(DEBUG_TYPE, "Passed", RMW->getFunction());
+          Remark << "A floating-point atomic instruction with no following use"
+                    " will generate an unsafe hardware instruction";

"A floating-point atomic instruction will generate an unsafe hardware instruction"

I am not sure what other details I could put in here
