+ If you are looking for DWARF-2 support, you are in the wrong file.
+ Go look in dwarf2read.c. This file is for the original DWARF.
+
+ DWARF (also known as DWARF-1) is headed for obsoletion.
+
+ In gcc 3.2.1, these targets prefer dwarf-1:
+
+ i[34567]86-sequent-ptx4* # TD-R2
+ i[34567]86-sequent-sysv4* # TD-R2
+ i[34567]86-dg-dgux* # obsolete in gcc 3.2.1, to be removed in 3.3
+ m88k-dg-dgux* # TD-R2
+ mips-sni-sysv4 # TD-R2
+ sparc-hal-solaris2* # TD-R2
+
+ Configurations marked with "# TD-R2" are on Zach Weinberg's list
+ of "Target Deprecation, Round 2". This is a candidate list of
+ targets to be deprecated in gcc 3.3 and removed in gcc 3.4.
+
+ http://gcc.gnu.org/ml/gcc/2002-12/msg00702.html
+
+ gcc 2.95.3 had many configurations which prefer dwarf-1.
+ We may have to support dwarf-1 as long as we support gcc 2.95.3.
+ This could use more analysis.
+
+ DG/UX (Data General Unix) used dwarf-1 for its native format.
+ DG/UX uses gcc for its system C compiler, but they have their
+ own linker and their own debuggers.
+
+ Takis Psarogiannakopoulos has a complete gnu toolchain for DG/UX
+ with gcc 2.95.3, gdb 5.1, and debug formats of dwarf-2 and stabs.
+ For more info, see PR gdb/979 and PR gdb/1013; also:
+
+ http://sources.redhat.com/ml/gdb/2003-02/msg00074.html
+
+ There may be non-gcc compilers that still emit dwarf-1.
