A method for recording and profiling information of a plurality of aborted transactions from a plurality of transactions is executed by processor core with a transactional memory, a transaction failure instruction address register (TFIAR), and a transaction failure data address register (TFDAR). The transactional memory stores information of a plurality of transactions executed by the processor core. The processor core retrieves instruction and data address associated with the aborted transaction from TFIAR and TFDAR respectively and stores them into a profiling table. The processor core then generates profiling information based on instruction and data addresses associated with the aborted transaction.
