PURPOSE:To provide source program transport with superior portability and execution efficiency by recognizing the delivery relation of data and the presence/absence of the type conversion in delivery of all the variables in a source program, and making them into graphs. CONSTITUTION:The variable on the source program is remarked, and for example, substitution between the variable and a data address, the substitution between the variables, and furthermore, reference information representing the execution content of reference of the data by the variable for the substitution relation of individual variable are generated and preserved. Thence, an oriented graph (substitution graph) with the substitution relation as an edge is generated setting the variable in reference information as a node, and a symbol for identification is attached on the variable referring to the data, and it is classified that the substitution graph is generated depending on which variable. Thence, byte order dependence information D comprised of the substitution graph to which the variable receiving the type conversion belongs, and a byte order dependence report R representing the variable requiring new coding to take the matching of byte order are generated. |
