Marian Buschsieweke	8b0007f33a	sys/atomic_utils: return previous value ... Update the `atomic_fetch_<OPERATION>_u<WIDTH>()` functions to return the old value the target contained prior to applying the operation. This makes this API much more versatile and closer to C11 atomics.	2020-12-16 18:09:35 +01:00
Marian Buschsieweke	5a2efe061d	sys: Moved volatile_utils from test ... The volatile utils might be useful elsewhere - at least in a second unit test. Move them to sys to allow using them, but with appropriate warnings added.	2020-11-24 14:34:51 +01:00
