            Bug ID: 105096
           Summary: --target-help not an alias for --help=target
           Product: gcc
           Version: 12.0
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P3
         Component: driver
          Assignee: unassigned at gcc dot gnu.org
          Reporter: vries at gcc dot gnu.org
  Target Milestone: ---

In common.opt, we read:
...
-target-help
Common Driver
Alias for --help=target.
...

But that doesn't seem to be correct, I get different results.

For instance, for nvptx target, we have an malias that atm is undocumented, and
we have:
...
$ cc1 --target-help 2>&1 | grep malias
$
...
and:
...
$ cc1 --help=target 2>&1 | grep malias
  -malias                               [disabled]
$...
