ARM:是从int原子写/读吗? [英] ARM: Is writing/reading from int atomic?

问题描述

不幸的是，在ARM体系结构上，我不确切知道它是什么芯片，是32位int读写原子吗?

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

关于对基本类型的读/写是否有某种保证?

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

推荐答案

它应该是原子的，除非该int存储在未对齐的地址上.

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