This updated patch also updates usage, like so (reformatted slightly
here to deal with wrapping):
...
$ dwz -?
dwz: Usage:
dwz [common options] [-h] [-m COMMONFILE] [-M NAME | -r] [FILES]
dwz [common options] -o OUTFILE FILE
dwz [ -v | -? ]
Common options:
...
--odr
--no-odr Enable/disable one definition rule
optimization.
Default value: Enabled.
--odr-mode <basic|link> Set aggressiveness level of one definition
rule optimization.
Default value: link.
...
Thanks,
- Tom

[odr] Add --odr/--no-odr and --odr-mode=<basic,link> command line options
Add optimization options --odr/--no-odr and --odr-mode=<basic|link>, making
the optimization user accessible.
2019-12-10 Tom de Vries <tdevries@suse.de>
* dwz.c (odr_parsed, no_odr_parsed, int odr_mode_parsed): New variable.
(dwz_options, dwz_common_options_help): Add --odr, --no-odr and
--odr-mode entries.
(print_options_help): Allow entries with NULL short_name and NULL msg.
(main): Handle --odr, --no-odr and --odr-mode.

Hi,
Add optimization options --odr/--no-odr and --odr-mode=<basic|link>, making
the optimization user accessible.
Any comments?
Thanks,
- Tom
