Bug ID: 104614
Summary: "Undocumented" option flag ignored with --help=target
Product: gcc
Version: 12.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: driver
Assignee: unassigned at gcc dot gnu.org
Reporter: rearnsha at gcc dot gnu.org
Target Milestone: ---
I don't know if this applies to other --help varieties, but in the Arm backend
we have some 'internal' options which we don't want the user to be using.
However, --help=target is still printing these out even though the manual
suggests these should be suppressed. For example, in arm.opt we have:
; Set to the name of target architecture which is required for
; multilib linking. This option is undocumented because it
; should not be used by the users.
mlibarch=
Target RejectNegative JoinedOrMissing NoDWARFRecord DriverOnly Undocumented
But the output of --help=target contains:
-mlibarch= This option lacks documentation.
Which is wrong.
Is there something else that needs to be done to suppress this output?
