Reimplement atomic code in inline assembly. This can improve optimisation, and avoids potential architectural problems with using LDREX/STREX intrinsics. API further extended: * Bitwise operations (fetch_and/fetch_or/fetch_xor) * fetch_add and fetch_sub (like incr/decr, but returning old value - aligning with C++11) * compare_exchange_weak * Explicit memory order specification * Basic freestanding template overloads for C++ This gives our existing C implementation essentially all the functionality needed by C++11. An actual Atomic<T> template based upon these C functions could follow. |
