Subject: 	PR c++/12266 	* cp-name-parser.y (struct demangle_info):
 Remove unused 	member PREV. 	(d_grab): Likewise. 	(allocate_info):
 Change return type to struct demangle_info *. 	Always allocate a new
 demangle_info. 	Remove unused PREV pointer. 
 (cp_new_demangle_parse_info): New function. 
 (cp_demangled_name_parse_free): New function. 
 (do_demangled_name_parse_free_cleanup): New function. 
 (make_cleanup_cp_demangled_name_parse_free): New function. 
 (cp_demangled_name_to_comp): Change return type to 	struct
 demangle_parse_info *. 	Allocate a new storage for each call. 
 (main): Update usage for cp_demangled_name_to_comp 	API change. 	*
 cp-support.h (struct demangle_parse_info): New structure. 
 (cp_demangled_name_to_comp): Update API change for 	return type. 
 (cp_new_demangle_parse_info): Declare. 
 (make_cleanup_cp_demangled_name_parse_free): New declaration. 
 (cp_demangled_name_parse_free): Declare. 	* cp-support.c
 (cp_canonicalize_string): Update API 	change for cp_demangled_name_to_comp. 
 (mangled_name_to_comp): Likewise. 	Return struct demangle_parse_info,
 too. 	(cp_class_name_from_physname): Update mangled_name_to_comp 	API
 change. 	(method_name_from_physname): Likewise. 	(cp_func_name): Update
 API change for cp_demangled_name_to_comp. 	(cp_remove_params): Likewise. 
 * python/py-type.c (typy_legacy_template_argument): Likewise.

	* cp-support.h (cp_canonicalize_string_no_typedefs): Declare.
	(cp_merge_demangle_parse_infos): Declare.
	* cp-support.c (ignore_typedefs): New file global.
	(copy_string_to_obstack): New function.
	(inspect_type): New function.
	(replace_typedefs): New function.
	(replace_typedefs_qualified_name): New function.
	(cp_canonicalize_string_no_typedefs): New function.
	* cp-name-parser.y (cp_merge_demangle_parse_infos): New function.
	(cp_new_demangle__parse_info): Allocate and initialize the obstack.
	* linespec.c (find_methods): Use cp_canonicalize_string_no_typedefs
	instead of cp_canonicalize_string.
	(find_method): Likewise.
	(decode_compound): Before looking up the name, call
	cp_canonicalize_string_no_typedefs.
	(decode_variable): Likewise.
