I've been waiting for DWARF 1 to come up.  Here are some random facts:

I've run the test suite with -gdwarf and -gdwarf+.  My results were
40+ ERRORs and 3400+ FAILs.

In gcc 3.2.2, these targets prefer DWARF 1:

  i[34567]86-dg-dgux*
  i[34567]86-sequent-ptx4*
  i[34567]86-sequent-sysv4*
  m88k-dg-dgux*
  mips-sni-sysv4
  sparc-hal-solaris2*

I also have a list for gcc 2.95.3, which is quite a bit longer.

  i[34567]86-dg-dgux*
  i[34567]86-ncr-sysv4*
  i[34567]86-sequent-ptx4*
  i[34567]86-sequent-sysv4*
  i[34567]86-*-osf1*
  i[34567]86-*-sco3.2v5*
  i[34567]86-*-sysv4*
  i860-alliant-*
  i860-*-sysv4*
  m68k-atari-sysv4*
  m68k-cbm-sysv4*
  m68k-*-sysv4*
  m88k-dg-dgux*
  m88k-*-sysv4*
  mips-sni-sysv4
  mips-*-gnu*
  sh-*-elf*
  sh-*-rtemself*
  sparc-hal-solaris2*
  sparc-*-sysv4*

The real hang-up is non-gcc compilers that emit DWARF 1.

I recall seeing two instances of that in bug reports in the past year, 
but I don't have URL's handy.
