Abstract
Embodiments relate to speculative branch handling for transaction abort. An aspect includes detecting a beginning of a current execution of a transaction. Another aspect includes, based on detecting the beginning of the transaction, disabling speculative execution based on branch prediction of an initial branch instruction of the transaction, wherein the initial branch instruction branches to two possible paths, and wherein a first path of the two possible paths comprises an abort handler. Another aspect includes disabling updating of a history table for the initial branch instruction.
