| If one was going to switch to dwarf, what would be the better dwarf to
| pick?  Dwarf 1, or 2?  I ask because quite a few different groups
| (processor abi groups) seem to picking up dwarf 1, and no one seems to
| be behind 2 (except Linux and sgi).

Dwarf 2 is a better debugging language.  The ABI groups are going with Dwarf 1
because it is a standard, and the Dwarf 2 group got caught in the changes in
the System V world and went under before having it become a standard.  The
PowerPC ABI group for instance has a bunch of changes to dwarf 1 to support C++
better.  From a practical point of view, the dwarf-2 code in gcc (and possibly
gdb) is still new enough that it may still have bugs.
