[LLVMdev] volatile optimisations

[Sarah Thompson]

Hi all,

What does LLVM assume when optimising volatiles? I'm finding difficulty 
generating multithreaded code that makes sense because the compiler 
seems to be assuming single-threaded semantics. Is there any special 
flags I should be using in order to safely generate multithreaded code?

 From my experiments, it very much appears that the generated code has 
been optimised in such a way that threading semantics is broken, and 
that volatile is not taken into account. Is this true? Is there a fix?

(This is a major showstopper, so any help would be greatly appreciated)

Thanks,
Sarah Thompson
