摘要：
A method and apparatus for efficient register checkpointing is herein described. A transaction is detected in program code. A recovery block is inserted in the program code to perform recovery operations in response to an abort of the first transaction. A roll-back edge is potentially inserted from an abort point to the recovery block. A control flow edge is inserted from the recovery block to a entry point of the transaction. Checkpoint code is inserted before the entry point to backup live-in registers in backup storage elements and recovery code is inserted in the recovery block to restor the live-in registers from the backup storage elements in response to an abort of the transaction.
