(gfc_match_submodule): Build up submodule filenames, using '@' as a delimiter. Store the output filename in 'submodule_name'. Similarly, the submodule identifier is built using '.' as an identifier. (gfc_dump_module): If current state is COMP_SUBMODULE, write to file 'submodule_name', using SUBMODULE_EXTENSION. (gfc_use_module): Similarly, use the 'submodule_name' field in the gfc_use_list structure and SUBMODULE_EXTENSION to read the implicitly used submodule files. 2015-07-17 Paul Thomas PR fortran/52846 * lib/fortran-modules.exp (proc cleanup-submodules): New procedure. * gfortran.dg/submodule_1.f08: Change extension and clean up the submodule files. * gfortran.dg/submodule_2.f08: ditto * gfortran.dg/submodule_6.f08: ditto * gfortran.dg/submodule_7.f08: ditto * gfortran.dg/submodule_8.f08: New test * gfortran.dg/submodule_9.f08: New test git-svn-id: svn+ssh://gcc.gnu.org/svn/gcc/trunk@225957 138bc75d-0d04-0410-961f-82ee72b054a4 --- diff --git a/gcc/testsuite/gfortran.dg/submodule_8.f08 b/gcc/testsuite/gfortran.dg/submodule_8.f08 new file mode 100644 index 000000000000..15a38a58833c --- /dev/null +++ b/gcc/testsuite/gfortran.dg/submodule_8.f08 @@ -0,0 +1,44 @@ +! { dg-do run } +! +!
