@itemx -gdwarf-@var{version}
|
|
Produce debugging information in DWARF format (if that is supported).
|
|
The value of @var{version} may be either 2, 3, 4 or 5; the default
|
|
-version for most targets is 5 (with the exception of VxWorks, TPF and
|
|
-Darwin / macOS, which default to version 2, and AIX, which defaults
|
|
-to version 4).
|
|
+version for most targets is 4 (with the exception of VxWorks, TPF and
|
|
+Darwin / macOS, which default to version 2).
|
|
|
|
Note that with DWARF Version 2, some ports require and always
|
|
use some non-conflicting DWARF 3 extensions in the unwind tables.
