| <h2 class="chapter">1 Overview of Stabs</h2> |
| |
| <p><dfn>Stabs</dfn> 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>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. |

| <!-- FIXME: Need to document all OS9000 stuff in GDB; see all references --> |
| <!-- to os9k_stabs in stabsread.c. --> |
| <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. |
