Let me state for the record that I do not use volatiles for thread
synchronization. But the issue at hand is not whether a volatile
can be used for full-featured thread synchronization, but whether
it can be used by one thread to signal a second looping thread to
quit.
It can.

I'm trying to port my application to Qt5. It's fine on my desktop machine

1. Qt 5.0 beta1
2. Beagleboard-xM
And the simplest application code is :

Hi,
thanks a lot Thiago for expanding on this, especially on those areas I didn't
have good knowledge about. I especially didn't know that all loads and stores
on x86 are fully ordered, reading something about a store buffer made me
believe otherwise.
Quite interesting topic, this.
Thanks,

shared in this interesting matter. I really learned something here.

Sure this is possible. Just start a timer and check if your document is

Hey guys. I'm having a lot of trouble compiling Qt5. Whether I try the packaged
