ARM: Is writing/reading from int atomic?

问题

On ARM architecture, unfortunately I don't know exactly what chip it is, is a 32 bit int read/write atomic?

Is there any sort of guarantees about reads/writes to basic types?

回答1:

It should be atomic, EXCEPT if that int is stored on a non-aligned address.
