Changed paths: M lib/system/freertos/mutex.h M lib/system/generic/mutex.h
Log Message: ----------- Stop using atomic_flag_*() for atomic_int in mutex
The atomic_flag_* functions are only defined for operands of the type atomic_flag so the previous implementation relied on undefined behavior. Because of the need for a read without side effects (in __metal_mutex_is_acquired), it is not possible to use the atomic_flags type for the mutex implementation. Because of this, all atomic_flag_* functions are replaced with the appropriate functions for atomic value types.
