Optimization for safe elimination of weak atomicity overhead

A system comprising:

• a machine readable medium including application code and compiler code, the compiler code, when executed, to
• compile at least a portion of the application code for execution with a processor, and
• maintain a state table during compilation of the portion of application code to indicate if shared data accessed within a transaction of the portion of application code is potentially conflictingly accessed non-transactionally;
• and
• wherein the processor is to execute the compiler code and the transaction of the application code, and wherein the processor is to not execute safety mechanism code associated with the transaction in response to the state table indicating the shared data accessed within the transaction is not potentially conflictingly accessed non-transactionally.

A method comprising:

• determining if data associated with a transactional memory access operation within a transaction is to be conflictingly accessed outside the transaction based on an entry of a state table associated with the data;
• performing a weak atomic safety mechanism in response to determining the data associated with the transactional memory access operation within the transaction is to be conflictingly accessed outside the transaction;
• and
• not performing the weak atomic safety mechanism in response to determining the data associated with the transactional memory access operation within the transaction is not to be conflictingly accessed outside the transaction.
