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.

||||

|
||||
|
||||
There may be non-gcc compilers that still emit dwarf-1.
