INPUT/OUTPUT LOCATION TRANSFORMATIONS WHEN EMULATING NON-TRACED CODE WITH A RECORDED EXECUTION OF TRACED CODE

Mapping input locations to enable execution of second executable code using trace data gathered during execution of first executable code. A trace of a prior execution of the first code, and the second code, are accessed. The trace stores data of an input that was consumed by first executable instructions of the first code. It is determined that the stored data of the input is usable as an input to second executable instructions of the second code. A difference in how the first instructions accessed the input during recording, as compared to how the second instructions expect to access input, is identified. Based on the identified difference, a location transformation is determined that would enable the second instructions to access the stored data. Execution of the second instructions is emulated using the stored data, including projecting the location transformation to enable the second instructions to access the stored data.
