摘要
A method and apparatus for ensuring integrity of transaction exit functions is herein described. Dead local data in a transaction is prevented from overwriting local variables associated with a transaction exit function. In a write-buffering Software Transactional Memory (STM) system, a commit function is associated with a private stack to store local variables to ensure write-back of local dead data in a write-buffer does not corrupt the commit function. Similarly, in a roll-back STM, an abort function is associated with a private stack to store local variables to ensure the roll-back of a program stack with local dead data from a write log does not corrupt the abort function. Alternatively, one stack may be used for the transaction including a first function and an exit function. Here, local dead variables are detected and prevented from overwriting local variables of the exit function.
