DEBUG option considerations

Use the DEBUG option with the XL C/C++ compilers to write DWARF debugging information. This debugging information can be written to an MVS™ data set or HFS file. Z Abend Investigator locates DWARF files from information in the load module.

DWARF files for all the compile units in a load module can be combined, together with source, into an MDBG side file (the CDADBGLD utility is used for this). Like DWARF, MDBG files can reside in an MVS data set or HFS file. MDBG files stored in MVS data sets are located via the HFZSYSDB DD. MDBG side files in HFS are self-locating, and as such must adhere to the following:
