![]() ![]() On the other hand, a non-volatile non-atomic load canīe moved across a volatile load freely, but not an Acquire load. Immediately followed by another Sequentiall圜onsistent store to the sameĪddress, the first store can be erased. A couple examples: if a Sequentiall圜onsistent store is Which ensures that every volatile load and store happens and is performed in the Other scenarios with atomic semantics, including static variables withĪtomic and volatile in the IR are orthogonal “volatile” is the C/C++ volatile,.Proper semantics for Java-style memory, for both volatile and regular.( C++11 draft available here.) ( C11 draft available here.) Optimized code generation for the following: The atomic instructions are designed specifically to provide readable IR and LLVM supports instructions which are well-defined in the presence of threads and
