Abstract
In a multi-threaded computer system that uses transactional memory, object fields accessed by only one thread are accessed by regular non-transactional read and write operations. When an object may be visible to more than one thread, access by non-transactional code is prevented and all accesses to the fields of that object are performed using transactional code. In one embodiment, the current visibility of an object is stored in the object itself. This stored visibility can be checked at runtime by code that accesses the object fields or code can be generated to check the visibility prior to access during compilation.
