[Bug fortran/23261] New: [meta-bug] gfortran testsuite bugs on mingw32

[fxcoudert at gcc dot gnu dot org]

I open this bug to keep track of the testcases failing on mingw32. With
gfortran-20050806, the list is:

 FAIL: gfortran.dg/dev_null.f90  (mingw doesn't have /dev/null)
 FAIL: gfortran.dg/direct_io_2.f90
 FAIL: gfortran.dg/endfile.f90
 FAIL: gfortran.dg/f2c_4.f90
 FAIL: gfortran.dg/f2c_5.f90
 FAIL: gfortran.dg/fmt_read_bz_bn.f90
 FAIL: gfortran.dg/g77/12632.f
 FAIL: gfortran.dg/g77/19990905-0.f
 FAIL: gfortran.dg/g77/970125-0.f
 FAIL: gfortran.dg/g77/980615-0.f
XPASS: gfortran.dg/g77/cabs.f

 FAIL: gfortran.dg/hollerith.f90

 FAIL: gfortran.dg/hollerith_f95.f90
 FAIL: gfortran.dg/io_invalid_1.f90
 FAIL: gfortran.dg/namelist_19.f90
 FAIL: gfortran.dg/output_exponents_1.f90
 FAIL: gfortran.dg/pr20865.f90
 FAIL: gfortran.dg/write_to_null.f90  (mingw doesn't have /dev/null)
 FAIL: gfortran.fortran-torture/execute/inquire_2.f90

Total: 20 bugs (two testcases are not supposed to work since mingw doesn't have
a /dev/null device).

------- Additional Comments From fxcoudert at gcc dot gnu dot org  2005-08-07 13:05 -------
With recent patch that fixes a number of issues with temporary files
(http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00399.html), and including the
bugs that are caused by the script not being perfect, the list reduces to:

 FAIL: gfortran.dg/direct_io_2.f90 (PR 23264)
 FAIL: gfortran.dg/endfile.f90 (PR 23262)
 FAIL: gfortran.dg/fmt_read_bz_bn.f90 (PR 23265)
 FAIL: gfortran.dg/output_exponents_1.f90
 FAIL: gfortran.fortran-torture/execute/inquire_2.f90 (PR 23272)

I have reduced each of those bugs (see PR number associated to each), which are
all target-specific. The output_exponents_1.f90 failure is associated to my
recent patch proposal (http://gcc.gnu.org/ml/gcc-patches/2005-08/msg00338.html),
i'm investigating...
