Dwarf 2 Standard

 

The Dwarf Standards Committee has been meeting since November, 1999, to discuss revisions and extensions to the Dwarf 2 Standard.  The participants are people who are interested in debugging, both as compiler developers or as debugger developers.  Participation is open to anyone who is interested.  We plan to release a public review copy of the revised Dwarf specification in mid-2001.

We have scheduled in person or teleconference meetings every two weeks at SGI in Mountain View, California, subject to cancelation if there are insufficient agenda items to warrant a meeting.  A significant amount of our discussion is held on email:  dwarf2@els.sgi.com.

If you have questions about the Dwarf 2 standard or the committee, please contact the committee chair, Michael Eager.

Documents:

Dwarf 2.0 base document.

Working Draft 6 (pdf) of the Dwarf 2 standard. 

Working Draft 6 (pdf) with differences from the Dwarf 2.0 base document highlighted. 

A document highlighting differences between Working Draft 5 and Working Draft 6.


Important note:  These are both internal working drafts.  They are subject to revision and modification and should not be relied on as standards.
