Re: When is "volatile" used instead of "lock" ?

I'd be interested in the disassembly if you can post it, it's going to take
me a while to get access to an IA64...

I should have asked this at the same time: does the "myValue = new
LazyInitClass();" code cause to emit an instruction with a "rel" completer?
Without that, one processor could have executed that instruction and has yet
to call Monitor.Exit while another processor is executing the read of
"myValue".

Yes I do and it's not emitting a ld.acq on IA64, the memory read has no
acquire semantics on X86/X64 either, but this is not relevant in case of
Vance's sample (fig 7) . What makes this work in V2. (as explained in
Vance's article you are referring to) is the strong write ordering in V2's
memory model, this irrespective the underlying HW platform.
