Abstract
The system creates, in a scheduler data structure, a first entry for a consumer instruction associated with a logical register ID. The first entry includes: a scheduler entry ID; a physical register ID allocated for the logical register ID; a checkpoint ID; one or more scheduler entry IDs for one or more prior producer instructions; and a release field which indicates whether to early release a physical register. The system updates a register alias table entry to include the scheduler entry ID and the checkpoint ID of the consumer instruction. The system receives the scheduler entry ID and a checkpoint ID for a respective prior producer instruction. Responsive to determining that the received checkpoint ID does not match the checkpoint ID associated with the consumer instruction, the system sets a release field to indicate that a physical register is to remain allocated.
