gcc/gcc/debug.h
Zack Weinberg 21d13d8372 debug.h (struct gcc_debug_hooks): Add type_decl field. 
* debug.h (struct gcc_debug_hooks): Add type_decl field.
	(debug_nothing_tree_int): Prototype.
	(dwarf_debug_hooks): Delete, unused.
	* debug.c (do_nothing_debug_hooks): Update.
	(debug_nothing_tree_int): New function.
	* langhooks.h (struct lang_hooks_for_decls):
	Remove builtin_type_decls field.
	* langhooks-def.h (LANG_HOOKS_BUILTIN_TYPE_DECLS): Delete.
	(LANG_HOOKS_DECLS): Update.
	* toplev.c (rest_of_decl_compilation, rest_of_type_compilation):
	Use debug_hooks->type_decl.
	* dbxout.c (preinit_symbols): New static.
	(dbx_debug_hooks, xcoff_debug_hooks): Update.
	(dbxout_init): Don't call DBX_OUTPUT_STANDARD_TYPES or
	lang_hooks.decls.builtin_type_decls.  Do scan preinit_symbols
	for symbols to output.
	(dbxout_type_decl): New function.
	(dbxout_symbol): If called before dbxout_init has run, queue
	the symbol for later.  Apply DBX_ASSIGN_FUNDAMENTAL_TYPE_NUMBER
	to TYPE_DECLs before emitting them.
	* xcoffout.c (assign_type_number): Delete.
	(xcoff_type_numbers): New static table.
	(xcoff_assign_fundamental_type_number): New function.
	* xcoffout.h: Define DBX_ASSIGN_FUNDAMENTAL_TYPE_NUMBER, not
	DBX_OUTPUT_STANDARD_TYPES.  Remove unnecessary #ifdefs.
	* sdbout.c: Include varray.h.
	(deferred_global_decls): New static.
	(sdb_debug_hooks): Update.
	(sdbout_global_decl): If we can't emit something right now,
	remember it in deferred_global_decls.
	(sdbout_finish): Just scan deferred_global_decls; don't call getdecls.
	(sdbout_init): Initialize deferred_global_decls.
	* Makefile.in: Update dependencies of sdbout.o.
	* dwarf2out.c (dwarf2out_type_decl): New function.
	(dwarf2_debug_hooks): Update.
	* vmsdbgout.c (vmsdbg_debug_hooks): Update.
	* c-decl.c (getdecls): Just return 0.
	(check_for_loop_decls): Don't use getdecls.
	(record_builtin_type): Call debug_hooks->type_decl on the TYPE_DECL.
	* c-objc-common.c (c_objc_common_finish_file): Don't use getdecls.
cp:
	* cp-lang.c: Don't define LANG_HOOKS_BUILTIN_TYPE_DECLS.
	* cp-tree.h: Don't declare cxx_builtin_type_decls.
	* decl.c (builtin_type_decls, cxx_builtin_type_decls): Delete.
	(record_builtin_type): Call debug_hooks->type_decl on the TYPE_DECL.
