[fpc-devel] A generic function for (multicore) cache flush?

Hello all,

Is there any good generic (portable) function to ensure memory cache 
flush for a thread on a multicore system?

What I'm trying to do is essentially fetch some debugging counters from 
multiple threads. They might happen to run on separate cores, thus 
having something pending in local cache sometimes. I would like to avoid 
EnterCriticalSection/ LeaveCriticalSection as such blocking would be a 
huge overkill, however it is still desireable to fetch reasonably 
current values. I'd like to avoid doing manual assembly as well (for 
portability reasons etc.).

Thanks a lot!
