Subject: cp-demangle.c (cp_demangle_type): Do not protect with IN_LIBGCC2.

2002-02-02  H.J. Lu  (hjl@gnu.org)

	* cp-demangle.c (cp_demangle_type): Do not protect with
	IN_LIBGCC2.
	(cplus_demangle_v3_all): New.
	(cplus_demangle_v3): Call cplus_demangle_v3_all.
	(cplus_demangle_v3_type): Call cplus_demangle_v3_all.

	* cplus-dem.c (cplus_demangle_v3_p): New function pointer.
	Initialized to cplus_demangle_v3.
	(cplus_demangle_with_style): Call cplus_demangle_v3_p instead
	of cplus_demangle_v3.
	(main): Set cplus_demangle_v3_p to cplus_demangle_v3_type for
	command line symbol.

	* testsuite/regress-demangle: Pass the mangled name at the
	command line.
