Accessing debugging information from a z/OS XL C/C++ compiler executable module

This information discusses how libddpi set up access to the debugging information in an executable module. Debugging information can be produced in many ways, including:

DWARF debugging information generated by IBM® z/OS® XL C/C++ compile.
ISD debugging information generated by IBM z/OS XL C/C++ compiler.
DWARF debugging information generated by IBM Enterprise COBOL compiler.
Debugging information generated by another compiler

The libddpi operations have been created specifically to set up access to executable modules created with the IBM z/OS XL C/C++ compiler. Accordingly, most of this information discusses how to use these functions.

The libddpi operations do not support GOFF program objects such as those in executable modules created with the IBM Enterprise COBOL compiler. For information on processing these executable modules, see Reading DWARF data from a GOFF program object file

Note: If a module has been created with another compiler, more development must be done to take the place of these operations. For more information, see Accessing other debugging information.
