ABSTRACT:
An arrangement is provided for data value recovery in an optimized program by precisely allocating predicate registers to guard branching instructions in the optimized program at compilation time. At execution time, an execution path leading to a recovery point is determined based on values of predicate registers guarding branching blocks. The values of non-current and non-resident data may be recovered at the recovery point according to the determined execution path. Optimization annotations may also be utilized for data value recovery.
