> There are several design problems with volatiles handling in Jitrino.JET that must be fixed:
> 1) Do not use abstract registers/real registers mapping in platform independent routines (see field ops)
> 2) Restore initial register operands after cmpxch8b operation.
> The are no known bugs in the current implementation, this is JET design related issue only.
