Compilation is initiated of previously-compiled code in which only a subset of the previously-compiled code was modified since a previous compilation. Thereafter, modified code corresponding to the subset of the previously-compiled code that was modified since the previous compilation is identified. Further, dependent code within the previously-compiled code that is dependent on the modified code is also identified. Using this information, only the identified modified code and the dependent code can be compiled. In some variations, at least a portion of the other parts of the previously-compiled code can be reused. Related apparatus, systems, techniques and articles are also described.
