A mechanism is provided for generating a checkpoint for a speculatively executed portion of code. The mechanisms identify, during a speculative execution of a portion of code, a register renaming operation occurring to an entry in a register renaming table of the processor. In response to the register renaming operation occurring to the register renaming table, a determination is made as to whether an update to an entry in a hardware-implemented recovery renaming table is to be performed. If so, the entry in the hardware-implemented recovery renaming table is updated. The entry in the recovery renaming table is part of the checkpoint for the speculative execution of the portion of code.
