Chapter 12. Understanding XL Fortran Compiler Listings

Partial Table-of-Contents

Diagnostic information is placed in the output listing produced by the -qlist, -qsource, -qxref, -qattr, -qreport, and -qlistopt compiler options. The -S option generates an assembler listing in a separate file.

To locate the cause of a problem with the help of a listing, you can refer to the following:

• The source section (to see any compilation errors in the context of the source program)
• The attribute and cross-reference section (to find data objects that are misnamed or used without being declared or to find mismatched parameters)
• The transformation and object sections (to see if the generated code is similar to what you expect)

A heading identifies each major section of the listing. A string of greater than symbols precede the section heading so that you can easily locate its beginning:

>>>>> section name

You can select which sections appear in the listing by specifying compiler options.
