Abstract
Debugging of computer programs is necessary for the development of the programs as well as for maintaining the operation of the programs. Symbolic debugging requires the ability to relate the current position in the object code program to the corresponding position in the source code. In the absence of compiler optimization, correlating the source and object code elements is a straightforward procedure. However, when the object code has been optimized, the relation between the source code constructs and object code instructions can become convoluted and complex. A correlation technique for optimized code is disclosed which maps the source constructs (source units) through each of the optimization operations by use of compilation nodes and associated source units to build a table which relates ranges of object instructions to the source units which produced the object instructions.
