32 /* This code implements a demangler for the g++ V3 ABI. The ABI is
33 described on this web page:
34 http://www.codesourcery.com/cxx-abi/abi.html#mangling
36 This code was written while looking at the demangler written by
37 Alex Samuel <samuel@codesourcery.com>.
39 This code first pulls the mangled name apart into a list of
40 components, and then walks the list generating the demangled
43 This file will normally define the following functions, q.v.:
44 char *cplus_demangle_v3(const char *mangled, int options)
45 char *java_demangle_v3(const char *mangled)
46 int cplus_demangle_v3_callback(const char *mangled, int options,
47 demangle_callbackref callback)
48 int java_demangle_v3_callback(const char *mangled,
49 demangle_callbackref callback)
50 enum gnu_v3_ctor_kinds is_gnu_v3_mangled_ctor (const char *name)
51 enum gnu_v3_dtor_kinds is_gnu_v3_mangled_dtor (const char *name)
53 Also, the interface to the component list is public, and defined in
54 demangle.h. The interface consists of these types, which are
55 defined in demangle.h:
56 enum demangle_component_type
57 struct demangle_component
59 and these functions defined in this file:
60 cplus_demangle_fill_name
61 cplus_demangle_fill_extended_operator
62 cplus_demangle_fill_ctor
63 cplus_demangle_fill_dtor
65 cplus_demangle_print_callback
66 and other functions defined in the file cp-demint.c.
68 This file also defines some other functions and variables which are
69 only to be used by the file cp-demint.c.
71 Preprocessor macros you can define while compiling this file:
74 If defined, this file defines the following functions, q.v.:
75 char *__cxa_demangle (const char *mangled, char *buf, size_t *len,
77 int __gcclibcxx_demangle_callback (const char *,
79 (const char *, size_t, void *),
81 instead of cplus_demangle_v3[_callback]() and
82 java_demangle_v3[_callback]().
85 If defined, this file defines only __cxa_demangle() and
86 __gcclibcxx_demangle_callback(), and no other publically visible
87 functions or variables.
90 If defined, this file defines a main() function which demangles
91 any arguments, or, if none, demangles stdin.
94 If defined, turns on debugging mode, which prints information on
95 stdout about the mangled string. This is not generally useful.
