Hello world,
This patch fixes and reorganizes dumping C prototypes. It makes the
following changes:
- BIND(C) types are now always output before any global symbols
- CFI_cdesc_t is issued for assumed shape and assumed rank arguments.
- BIND(C,NAME="...") entities were not always issued.
gcc/fortran/ChangeLog:
PR fortran/118359
* dump-parse-tree.cc (show_external_symbol): New function.
(write_type): Add prototype, put in restrictions on what not to dump.
(has_cfi_cdesc): New function.
(need_iso_fortran_binding): New function.
(gfc_dump_c_prototypes): Adjust to take only a file output. Add
"#include <ISO_Fortran_binding.h" if CFI_cdesc_t is found.
Traverse global namespaces to dump types and the globalsymol list
to dump external symbols.
(gfc_dump_external_c_prototypes): Traverse global namespaces.
(get_c_type_name): Handle CFI_cdesc_t.
(write_proc): Also pass array spec to get_c_type_name.
* gfortran.h (gfc_dump_c_prototypes): Adjust prototype.
* parse.cc (gfc_parse_file): Adjust call to gfc_dump_c_prototypes.
Regression-tested. As for testcases... as the dump is to
standard output, I don't know how to do that. If anybody
has an idea, please let me know.
OK for trunk?
Best regards
Thomas
