            Bug ID: 95472
           Summary: various diagnostics for C/C++ hyperlinks to gfortran
                    doc
           Product: gcc
           Version: 10.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: middle-end
          Assignee: unassigned at gcc dot gnu.org
          Reporter: xry111 at mengyan1223 dot wang
  Target Milestone: ---

$ cat t1.c
int main()
{
        int x;
        return x;
}
$ gcc t1.c -Wall
t1.c: In function 'main':
t1.c:4:9: warning: 'x' is used uninitialized in this function [-Wuninitialized]
    4 |  return x;
      |         ^

It looks OK, but in GCC-10 we have diagnostics with hyperlink.  If you click "-
Wuninitialized" you'll be diverted to gfortran doc:

https://gcc.gnu.org/onlinedocs/gfortran/Error-and-Warning-Options.html#index-Wuninitialized

This also happens to -Wreturn-type and -Wuninitialized.  Strangely these two
entries don't even exist in gfortran doc.  But it does not happens to -Wformat
or -Wimplicit-function-declaration etc.

Sorry I can't type.  Should be:

This also happens to -Wreturn-type.  Strangely the entries for -Wreturn-type
and -Wuninitialized don't even exist in gfortran doc.

Well, seems fixed by Jakub at efaffc69 (in master) and a764bbb7 (in gcc-10) so
far.
