K 10 svn:author V 2 dg K 8 svn:date V 27 1995-12-21T19:20:58.000000Z K 7 svn:log V 293 Rewrote most of the ddb stack traceback code. These changes are smarter about decoding trap/syscall/interrupt frames and generally works better than the previous stuff. Removed some special (incorrect) frobbing of the frame pointer that was messing some things up with the new traceback code. END
