A disjunction is applied by this script for the semantic patch language. This construct uses short-circuit evaluation. It has got the consequence that the last element of the specified condition will only be checked if all previous parts did not match. Such a technical detail leads to a recommended ordering of condition parts if you would like to care for optimal run time characteristics of SmPL code. An usage incidence was determined for the specified identifiers in source files from the software “Linux next-20201023” by another SmPL script. This analysis result indicated that a few functions were called more frequent than others. Thus reorder the SmPL disjunction items partly according to their usage incidence.
