PR exp/9514:
* parser-defs.h (insert_type, insert_type_address_space): Declare.
(push_type_address_space): Remove.
* parse.c (insert_into_type_stack): New function.
(insert_type): Likewise.
(insert_type_address_space): Rename from push_type_address_space.
Insert tp_space_identifier.
* c-exp.y (ptr_operator): New production.
(abs_decl): Use ptr_operator.
(space_identifier): Call insert_type_address_space.
(ptype): Don't use const_or_volatile_or_space_identifier.
(const_or_volatile_noopt): Call insert_type.
(conversion_type_id, conversion_declarator): New productions.
(operator): Use conversion_type_id.
testsuite
* gdb.base/whatis.exp: Add tests.
