Martin Schwidefsky 39475179d4 [S390] Improve code generated by atomic operations. ... Git commit ea43546750 changed the definition of atomic_t and atomic64_t for s390 by adding the volatile modifier to the counter field. This has an unfortunate side effect with newer versions of the gcc. The typeof operator now picks up the volatile modifier from the expression. This causes the compiler to think that it has to store the two temporary variable old_val and new_val in the __CS_LOOP for the different atomic operations to the stack as the variables are now volatile. Both stores are superfluous. The hack to replace typeof(ptr->counter) with int in __CS_LOOP and and long long in __CSG_LOOP avoids the two stores. A better solution would be to drop the volatile from the counter field of the atomic_t and atomic64_t definition. But that is a touchy subject ..
