[PATCH,Fortran 0/7] delete some unused decls, make static

[PATCH,Fortran 0/7] delete some unused decls, make static

[Bernhard Reutner-Fischer]

Hi!

Quickly skimming through the frontend headers.
There are a couple of declarations for functions that do not have
definitions. And there are a couple of functions that can be static.

Notes i took while at it / TODOs:

- get rid of VTAB_GET_FIELD_GEN and unused extern decls
- The last block of gfc_trans_vla_one_sizepos() could simply use
  gfc_evaluate_now_function_scope(). Passing down unshared val of course.
- trans-expr.c has one use of gfc_evaluate_now_loc() but should simply use
  gfc_evaluate_now() there; Calling ...now_loc(input_location) is superfluous
- s/mane/name/;# in git grep -w mane gcc/fortran/
- delete gfc_match_small_int, use gfc_match_small_literal_int instead
- move gfc_match_null definition up before first user, make it static
  and delete decl from match.h
- gfc_cpp_add_include_path_after move up, make static, rm external decl
- gfc_walk_array_ref move up, make static, rm external decl
- delete unused gfc_copy_only_alloc_comp ?
- delete unused gfc_conv_descriptor_attribute ?
- gfc_build_nan str arg is "" always. Delete parameter and handling?
- delete unused gfc_simplify_get_team or wire it up in intrinsics,
  get_team handling (instead of the NULL..)

Anyone who does coarrays might want to fill in the missing get_team()
simplify and add an appropriate test. That's the only thing that i will
not do as i once was more into MPI and verbs so won't ever do coarrays ;)

Bootstraps fine, regression tests running over night.
Ok for trunk if it passes?

thanks,

[PATCH,Fortran 1/7] Fortran: make some trans* functions static

[Bernhard Reutner-Fischer]

From: Bernhard Reutner-Fischer <aldot@gcc.gnu.org>

This makes some trans* functions static and deletes declarations of
functions that either do not exist anymore like gfc_get_function_decl
or that are unused like gfc_check_any_c_kind.

gcc/fortran/ChangeLog:

	* expr.c (is_non_empty_structure_constructor): Make static.
	* gfortran.h (gfc_check_any_c_kind): Delete.
	* match.c (gfc_match_label): Make static.
	* match.h (gfc_match_label): Delete declaration.
	* scanner.c (file_changes_cur, file_changes_count,
	file_changes_allocated): Make static.
	* trans-expr.c (gfc_get_character_len): Make static.
	(gfc_class_len_or_zero_get): Make static.
	(VTAB_GET_FIELD_GEN): Undefine.
	(gfc_get_class_array_ref): Make static.
	(gfc_finish_interface_mapping): Make static.
	* trans-types.c (gfc_check_any_c_kind): Delete.
	(pfunc_type_node, dtype_type_node, gfc_get_ppc_type): Make static.
	* trans-types.h (gfc_get_ppc_type): Delete declaration.
	* trans.c (gfc_msg_wrong_return): Delete.
	* trans.h (gfc_class_len_or_zero_get, gfc_class_vtab_extends_get,
	gfc_vptr_extends_get, gfc_get_class_array_ref, gfc_get_character_len,
	gfc_finish_interface_mapping, gfc_msg_wrong_return,
	gfc_get_function_decl): Delete declaration.

Re: [PATCH,Fortran 1/7] Fortran: make some trans* functions static

Hi Bernhard,

what you're doing seems a useful clean-up, thanks.

One point for discussion:

> -match
> +static match
>   gfc_match_label (void)

I have generally understood that the gfc_ prefix is for global variables
and functions only.  We do not always adhere to it (also since some
global functions were made static previously), but I think we should
stick to it, unless other people think otherwise :-)

Best regards

	Thomas

I concur – but there is also a good reason for always having a prefix:
It makes it more unlikely that there are name clashes between the
middle/backend end and the FE. – And those should be strictly avoided as
it makes debugging (in the debugger) harder. (And in particular, same
file names should be avoided.)

I think there is also some attempt to avoid same names in multiple FE,
but that's not as strict as long as different binaries are produced and
'git grep' does also show the directory.

For the readability, it could be sometimes useful to know whether a
function is a FE function or not.

Thus, I am not sure whether it is better to always have the prefix or
not – there are arguments for either.

I would put it the other way round:
At least global functions (and variables) should use the gfc_ prefix to
ease debugging and grep.

That said, I deliberately did not rename any of the functions, also to
avoid needless churn.

OK.

Thanks for the cleanup!

[PATCH,Fortran 2/7] Fortran: make some match* functions static

[Bernhard Reutner-Fischer]

From: Bernhard Reutner-Fischer <aldot@gcc.gnu.org>

gfc_match_small_int_expr was unused, delete it.
gfc_match_gcc_unroll should use gfc_match_small_literal_int and then
gfc_match_small_int can be deleted since it will be unused.

gcc/fortran/ChangeLog:

	* decl.c (gfc_match_old_kind_spec, set_com_block_bind_c,
	set_verify_bind_c_sym, set_verify_bind_c_com_block,
	get_bind_c_idents, gfc_match_suffix, gfc_get_type_attr_spec,
	(check_extended_derived_type): Make static.
	(gfc_match_gcc_unroll): Add comment.
	* match.c (gfc_match_small_int_expr): Delete definition.
	* match.h (gfc_match_small_int_expr): Delete declaration.
	(gfc_match_name_C, gfc_match_old_kind_spec, set_com_block_bind_c,
	set_verify_bind_c_sym, set_verify_bind_c_com_block,
	get_bind_c_idents, gfc_match_suffix,
	gfc_get_type_attr_spec): Delete declaration.

[PATCH,Fortran 3/7] Fortran: make some constructor* functions static

[Bernhard Reutner-Fischer]

From: Bernhard Reutner-Fischer <aldot@gcc.gnu.org>

gfc_constructor_expr_foreach and gfc_constructor_swap were just stubs.

gcc/fortran/ChangeLog:

	* constructor.c (gfc_constructor_get_base): Make static.
	(gfc_constructor_expr_foreach, (gfc_constructor_swap): Delete.
	* constructor.h (gfc_constructor_get_base): Remove declaration.
	(gfc_constructor_expr_foreach, (gfc_constructor_swap): Delete.

I'm also attaching the other view for the fortran FE after the header
cleanup:

python3 $topsrc/contrib/unused_functions.py gcc/fortran/ \
  grep -v "gt_"

for a guesstimate list of
 Symbol 'foo' declared extern but never referenced externally

Down to about 50 for f951 as we want to keep the debug ones of course.

For other language frontends see the head of the script;
Back then there was no D nor modula2, and a go sample is missing, too.
Should be rather straight forward if anyone is curious. You can just
abbreviate the list of objects that are used to link your frontend.
Archives are supposedly handled fine, at least last time i tried.

HTH,

Tested with no regressions on x86_64-unknown-linux {-m32,-m64}.
Ok for trunk?
