METHOD FOR PREVENTING DATA INCONSISTENCY BETWEEN ACCESSES OF DIFFERENT FUNCTIONS OF AN APPLICATION TO A GLOBAL VARIABLE IN A DATA PROCESSING INSTALLATION

摘要

The aim of the invention is to prevent data inconsistency between accesses of different functions of an application to a global variable in a data processing system. To this end, a) a symbolic object code of a group of functions (O1, ..., Om) to be carried out in the data processing system is provided, and the functions (O1, O2, On, Om) which are described as interfering functions and access a similar global variable are identified; b) at least one of the interfering functions is selected; c) a step (I) is added for the initialisation of an auxiliary variable with the value of the global variable in the object code of each function selected in step b) or a function calling a selected function before the call thereof; and d) a symbol of the global variable in the object code of the selected function is replaced by a reference to a storage space of the auxiliary variables.
