            Bug ID: 95027
           Summary: -fdiagnostics-urls generates wrong URLs
           Product: gcc
           Version: 10.1.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c
          Assignee: unassigned at gcc dot gnu.org
          Reporter: harald at gigawatt dot nl
  Target Milestone: ---

$ cat test.c
int f() {
  int i;
  return i;
}
$ LC_ALL=C gcc-10.1.0 -Wall -c test.c -fdiagnostics-urls=always 2>&1 | cat -v
test.c: In function 'f':
test.c:3:10: warning: 'i' is used uninitialized in this function
[^[]8;;https://gcc.gnu.org/onlinedocs/gfortran/Error-and-Warning-Options.html#index-Wuninitialized^G-Wuninitialized^[]8;;^G]
    3 |   return i;
      |          ^

Wuninitialized is documented at
https://gcc.gnu.org/onlinedocs/gcc/Warning-Options.html#index-Wuninitialized
rather than
https://gcc.gnu.org/onlinedocs/gfortran/Error-and-Warning-Options.html#index-Wuninitialized.

Wuninitialized is present in both gcc/common.opt and gcc/fortran/lang.opt, but
only documented in the former, so the former should be used for generating the
URL. gcc/opts.c's get_option_html_page contains a hardcoded list of flags that
appear in gcc/fortran/lang.opt but are not documented there, but this list is
not complete.
