Abstract:
Methods, systems, and apparatuses to provide an XABORT in a transactional memory access system are described. In one embodiment, the stored value is a context value indicating the context in which a transactional memory execution was aborted. A fallback handler may use the context value to perform a series of operations particular to the context in which the abort occurred.
