Hi,

 

In search of a std:atomic<T> implementation, I decided
to give boost.atomic library a try. My initial investigation found it worked
fine under linux.  However it does not
work on Windows.

 

Here is a little test program to demonstrate:

 

#include <iostream>

#include <boost/atomic.hpp>

#include <boost/lockfree/detail/tagged_ptr.hpp>

#include <boost/lockfree/detail/freelist.hpp>

 

int main()
{

       boost::lockfree::caching_freelist<int>
pool(3);

       int* pInt1 = pool.allocate();

       *pInt1 = 1;

       int* pInt2 = pool.allocate();

       *pInt2 = 2;

       int* pInt3 = pool.allocate();

       *pInt3 = 3;

       pool.deallocate(pInt1);

       pool.deallocate(pInt2);

       pool.deallocate(pInt3);

       int* pInt4 = pool.allocate();

       int* pInt5 = pool.allocate();

       int* pInt6 = pool.allocate();

       

}

 

 

The test uses boost.lockfree library, which you can download
from http://tim.klingt.org/git?p=boost_lockfree.git

 

If you set a break point, say in fallback.hpp, you will see
that on Windows it falls back to spinlock.

 

Can somebody please suggest how to fix this?

 

I suspect the issue has something to do with intptr_t type.

 

I looked into the code but quickly started to have
headache.  Atomic library uses template
metaprogramming and is not easy to understand.
