            Bug ID: 114191
           Summary: Flags "Warning" and "Target" don't mix well in
                    target.opt files
           Product: gcc
           Version: 13.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: other
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gjl at gcc dot gnu.org
  Target Milestone: ---

In an .opt file, a backend can define target-specific diagnostic options, f=
or
example gcc/config/avr/avr.opt has:

Wmisspelled-isr
Warning C C++ Var(avr_warn_misspelled_isr) Init(1)
Warn if the ISR is misspelled, ...

This is a "Target" option however (so it should be listed with --help=3Dtar=
get,
which it currently is not). However, specifying the "Target" flag in avr.opt
makes the option no more recognizable:

$ avr-gcc main.c -c -Wall -Wmisspelled-isr
cc1: error: unrecognized command-line option '-Wmisspelled-isr'

I can reproduce this for target avr, but it likely affects all other target=
s as
well.

Set the component to "other". As it appears, there is no bugzilla component=
 for
such internal problems.=
