<h2 class="chapter">1 Overview of Stabs</h2>
|
||
|
|
|
||
|
|
<p><em>Stabs</em> refers to a format for information that describes a program
|
||
|
|
to a debugger. This format was apparently invented by
|
||
|
|
Peter Kessler at
|
||
|
|
the University of California at Berkeley, for the <code>pdx</code> Pascal
|
||
|
|
debugger; the format has spread widely since then.
|
||
|
|
</p>
|
||
|
|
<p>This document is one of the few published sources of documentation on
|
||
|
|
stabs. It is believed to be comprehensive for stabs used by C. The
|
||
|
|
lists of symbol descriptors (see <a href="Symbol-Descriptors.html#Symbol-Descriptors">Symbol Descriptors</a>) and type
|
||
|
|
descriptors (see <a href="Type-Descriptors.html#Type-Descriptors">Type Descriptors</a>) are believed to be completely
|
||
|
|
comprehensive. Stabs for COBOL-specific features and for variant
|
||
|
|
records (used by Pascal and Modula-2) are poorly documented here.
|
||
|
|
</p>
|
||
|
|
|
||
|
|
<p>Other sources of information on stabs are <cite>Dbx and Dbxtool
|
||
|
|
Interfaces</cite>, 2nd edition, by Sun, 1988, and <cite>AIX Version 3.2 Files
|
||
|
|
Reference</cite>, Fourth Edition, September 1992, "dbx Stabstring Grammar" in
|
||
|
|
the a.out section, page 2-31. This document is believed to incorporate
|
||
|
|
the information from those two sources except where it explicitly directs
|
||
|
|
you to them for more information.
