Subject: [boost] REQ: Looking for access to a Haswell machine to test Boost memory transactions code

Dear Boost Devs,
Last night I may have implemented some Boost macro based support for
simple memory transactions. Basically one does this:
STLLockable lockable;
...
BOOST_BEGIN_MEMORY_TRANSACTION(lockable)
{
// Transaction code
}
BOOST_END_MEMORY_TRANSACTION(lockable)
This can turn into __transaction_relaxed, or Intel TSX falling back
onto a spin lock. It's very simple, but it ought to work and with
very significant performance improvements on TSX capable hardware.
The problem is that I don't have access to an Intel Haswell CPU to
test the code upon. I think its design is correct through
introspection, but if a kind Boost dev could lend me access to their
Haswell machine via SSH - or even just offer to debug some binaries
for me, I would be very grateful.
Thanks,
Niall
