title: Are C++ int operations atomic on the mips architecture
body: <p>I wonder if I could read or write shared int value without locking on mips cpu (especially Amazon or Danube). What I mean is if such a read or write are atomic (other thread can't interrupt them). To be clear - I don't want to prevent the race between threads, but I care if int value itself is not corrupted.</p>
  
  <p>Assuming that the compiler aligns all ints at the boundaries of cpu word, it should be possible. I use gcc (g++). Tests also shows that it seems work correctly. But maybe someone knows it for sure?</p>
