Phasing out Dwarf 1?

[Michael Elizabeth Chastain]

I would like to phase out support for the Dwarf 1 debug format.

I did some research and wrote the results as comments in dwarfread.c.
I found reports from gdb users with three different compilers mentioned:

  gcc
  diab
  absoft

All of these compilers now have released versions with dwarf-2 support.
gcc 3.4.0 has no more dwarf-1 at all.

My idea is to ask the steering committee to adopt a roadmap for
phasing out Dwarf 1 support.

What do you think?
