Abstract
Presenting historical state associated with prior execution of an entity. Based on replaying segment(s) of execution of an entity based on a trace, embodiments could present an indication of whether a value of a code element is, at a first execution time point, unknown, known, previously known, and/or known in the future. Additionally, or alternatively, embodiments could present an indication of a value relied upon by simulated execution of a function at a second execution time point, along with an indication of a timing of knowledge of the value in relation to the second execution time point. Additionally, or alternatively, embodiments could present an indication that a return value of a function would be known if the function had executed at a third execution time point, or an indication that the return value would be unknown if the function had executed at the third execution time point.
