howto demangle const types?

[Larry Evans]

The attached code produces output:

int const=int

IOW, the abi::__cxa_demangle strips const qualifiers.

Looking at:

  http://gcc.gnu.org/viewcvs/trunk/libiberty/cp-demangle.h?view=markup

shows:

99 	 /* The options passed to the demangler. */
...
165 	extern void
166 	cplus_demangle_init_info (const char *, int, size_t, struct d_info *);

and the following:


http://gcc.gnu.org/viewcvs/trunk/libiberty/cp-demangle.c?revision=166810&view=markup

shows:


1129    if (dc != NULL && top_level && (di->options & DMGL_PARAMS) == 0)
1130      {
1131        /* Strip off any initial CV-qualifiers, as they really apply
1132           to the `this' parameter, and they were not output by the
1133           v2 demangler without DMGL_PARAMS. */

so maybe I just need to pass the proper di->options to some function,
probably the one mentioned here:

43      This file will normally define the following functions, q.v.:
44      char *cplus_demangle_v3(const char *mangled, int options)

However, the only documentation of options in this file are:

4865 	/* Entry point for the demangler. If MANGLED is a g++ v3 ABI mangled
4866 	name, return a buffer allocated with malloc holding the demangled
4867 	name. OPTIONS is the usual libiberty demangler options. On
4868 	success, this sets *PALC to the allocated size of the returned
4869 	buffer. On failure, this sets *PALC to 0 for a bad name, or 1 for
4870 	a memory allocation failure, and returns NULL. */
4871 	
4872 	static char *
4873 	d_demangle (const char *mangled, int options, size_t *palc)

However, there's no link to where these "usual libiberty demangler
options" are described.

Also, how can I allow the linker to find cplus_demangle_v3?

TIA.
