binutils-gdb/gdb/ada-lang.h
Simon Marchi de93309a38 Clean up ada-lang.h 
This patch cleans up ada-lang.h:

- Some functions just don't exist anymore, remove their declaration
- Some functions are implemented in ada-lang.c and only used there, make
  them static to that file.

I moved some functions higher in the file to avoid having to
forward-declare them, but the implementations are unchanged.

gdb/ChangeLog:

	* ada-lang.h (GROW_VECT): Move to ada-lang.c.
	(grow_vect): Remove declaration.
	(ada_type_of_array): Remove declaration.
	(ada_update_initial_language): Remove declaration.
	(ada_fold_name): Remove declaration.
	(ada_fill_in_ada_prototype): Remove declaration.
	(user_select_syms): Remove declaration.
	(get_selections): Remove declaration.
	(ada_tag_type): Remove declaration.
	(ada_value_tag): Remove declaration.
	(ada_is_others_clause): Remove declaration.
	(ada_in_variant): Remove declaration.
	(ada_value_struct_elt): Remove declaration.
	(ada_attribute_name): Remove declaration.
	(ada_system_address_type): Remove declaration.
	* ada-lang.c (ada_watch_location_expression): Make static.
	(GROW_VECT): Move here from ada-lang.h.
	(grow_vect): Make static.
	(ada_update_initial_language): Make static.
	(ada_fold_name): Make static.
	(ada_type_of_array): Make static.
	(encoded_ordered_before): Move up.
	(sort_choices): Move up.
	(print_signatures): Move up.
	(ada_print_symbol_signature): Move up.
	(get_selections): Move up and make static.
	(user_select_syms): Move up and make static.
	(ada_value_struct_elt): Move up and make static.
	(ada_tag_type): Make static.
	(ada_value_tag): Make static.
	(ada_is_others_clause): Make static.
	(ada_in_variant): Make static.
	(ada_attribute_name): Make static.
