[M3devel] atomics questions

[Jay K]

What if some atomic operations aren't available?

 

 

If none are available, then they can all fallback to one giant lock.

 

 

But what if some are and some aren't?

 

 

A lock per type?

 

That fails with like

 union {
  short s[2];

  int i;

} u;

 

 

and platform has atomic int but not atomic short.
