> I don't think volatile matters. AFAIK, what you need is _Atomic (C11). If we can make this thread safe with C11, I think it's fine to document that mini-gmp requires C11 for thread safety. (I'd still prefer the simpler way of reying on float.h constants, though). Let's remind ourselves that we are not executing GMP on a standards document, but on actual computer systems. :-) Store reordering is an actual problem which we should keep in mind (but note that x86 implements total store ordering). Non-atomic loads/stores is not as long as we keep to short types. -- Torbjörn Please encrypt, key id 0xC8601622 _______________________________________________ gmp-devel mailing list firstname.lastname@example.org https://gmplib.org/mailman/listinfo/gmp-devel
