            Bug ID: 100158
           Summary: Some issues with fortran testsuite files
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: fortran
          Assignee: unassigned at gcc dot gnu.org
          Reporter: gscfq@t-online.de
  Target Milestone: ---

In the following some issues with fortran test files itself :

---

Two test files substr* are placed at top level,
should be better moved to catalog gfortran.dg

$ ls ./gcc-11-20210418/gcc/testsuite
   200704 19. Apr 00:32 gfortran.dg
       57 19. Apr 00:32 gfortran.fortran-torture
      438 19. Apr 00:32 substr_10.f90
      766 19. Apr 00:32 substr_9.f90

---

pr100018 contributed a file PR10018.f90 in gfortran.dg,
with a missing digit, should be renamed to PR100018.f90

---

These two testsuite files are identical,
one seems to be superfluous :

$ diff gfortran.dg/pr99602c.f90 gfortran.dg/pr99602d.f90
$

---

Some testsuite files disappeared without an entry in ChangeLog*.
What happend with dtio_5.f90 and pdt_5.f03 ?

They existed here :
./gcc-10-20200110/gcc/testsuite/gfortran.dg/pdt_5.f03
./gcc-10-20200110/gcc/testsuite/gfortran.dg/dtio_5.f90

---

Other testsuite files existed here and are later gone somehow
without an entry in ChangeLog* :

./gcc-8-20201210/gcc/testsuite/gfortran.dg/external_procedures_4.f90

./gcc-7-20191107/gcc/testsuite/gfortran.dg/pr78686.f90

./gcc-7-20191107/gcc/testsuite/gfortran.dg/pr91686.f90

./gcc-5-20171003/gcc/testsuite/gfortran.dg/pr58754.f90
