31/* This code implements a demangler for the g++ V3 ABI. The ABI is
32 described on this web page:
33 http://www.codesourcery.com/cxx-abi/abi.html#mangling
34
35 This code was written while looking at the demangler written by
36 Alex Samuel <samuel@codesourcery.com>.
37
38 This code first pulls the mangled name apart into a list of
39 components, and then walks the list generating the demangled
40 name.
41
42 This file will normally define the following functions, q.v.:
43 char *cplus_demangle_v3(const char *mangled, int options)
44 char *java_demangle_v3(const char *mangled)
45 enum gnu_v3_ctor_kinds is_gnu_v3_mangled_ctor (const char *name)
46 enum gnu_v3_dtor_kinds is_gnu_v3_mangled_dtor (const char *name)
47
48 Also, the interface to the component list is public, and defined in
49 demangle.h. The interface consists of these types, which are
50 defined in demangle.h:
51 enum demangle_component_type
52 struct demangle_component
53 and these functions defined in this file:
54 cplus_demangle_fill_name
55 cplus_demangle_fill_extended_operator
56 cplus_demangle_fill_ctor
57 cplus_demangle_fill_dtor
58 cplus_demangle_print
59 and other functions defined in the file cp-demint.c.
60
61 This file also defines some other functions and variables which are
62 only to be used by the file cp-demint.c.
63
64 Preprocessor macros you can define while compiling this file:
65
66 IN_LIBGCC2
67 If defined, this file defines the following function, q.v.:
68 char *__cxa_demangle (const char *mangled, char *buf, size_t *len,
69 int *status)
70 instead of cplus_demangle_v3() and java_demangle_v3().
71
72 IN_GLIBCPP_V3
73 If defined, this file defines only __cxa_demangle(), and no other
74 publically visible functions or variables.
75
76 STANDALONE_DEMANGLER
77 If defined, this file defines a main() function which demangles
78 any arguments, or, if none, demangles stdin.
79
80 CP_DEMANGLE_DEBUG
81 If defined, turns on debugging mode, which prints information on
82 stdout about the mangled string. This is not generally useful.
