Update of /cvsroot/src/sys/arch/alpha/alpha
In directory netbsd1:/var/slash-tmp/cvs-serv29573

Added Files:
        db_disasm.c db_instruction.h db_interface.c db_trace.c 
Log Message:
Add support for DDB (in-kernel debugger) to NetBSD/alpha, based on
such code for Mach 3's Alpha port.  Initially reworked for NetBSD/alpha
by Chris Demetriou, and then heavily hacked on by me.  Works, but is still
a little rough around the edges.  Known problems:

- Error recovery could be improved a bit.
- Back traces don't work.
- Single-stepping can be flaky, at times.  (Alpha doesn't have hardware
  support for single-stepping, and I'm not entirely convinced the
  MI DDB software-emulated single-stepping logic is 100% correct.)
- Logic for when to drop into DDB needs some improvement.
