Produce debugging information in DWARF version 2 format (if that is
supported). This is the format used by DBX on IRIX 6. With this
option, GCC uses features of DWARF version 3 when they are useful;
version 3 is upward compatible with version 2, but may still cause
problems for older debuggers.

Produce debugging information in DWARF format (if that is
supported). This is the format used by DBX on IRIX 6. The value
of @var{version} may be either 2 or 3; the default version is 2.
Note that with DWARF version 2 some ports require, and will always
use, some non-conflicting DWARF 3 extensions in the unwind tables.
