xref

Syntax

    -qxref | -qnoxref 
    XREF | NOXREF 

Purpose
Produces a compiler listing that includes a cross-reference listing of all identifiers.

Notes
Usage modes for xref are:

-qxref=full	Reports all identifiers in the program.
-qxref	Reports only those identifiers that are used.

The noprint option overrides this option.

Any function defined with the #pragma mc_func function_name directive is listed as being defined on the line of the #pragma directive.

Example
To compile myprogram.c and produce a cross-reference listing of all identifiers whether they are used or not, enter:

xlC myprogram.c -qxref=full -qattr

A typical cross-reference listing has the form:
