DD		 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
35
36 This code was written while looking at the demangler written by
37 Alex Samuel <samuel@codesourcery.com>.
38
39 This code first pulls the mangled name apart into a list of
40 components, and then walks the list generating the demangled
41 name.
42
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)
208c1674
DD		 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)
858b45cf
DD		 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)
52
59727473
DD		 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
208c1674 58 demangle_callbackref
59727473
DD		 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
64 cplus_demangle_print
208c1674 65 cplus_demangle_print_callback
59727473
DD		 66 and other functions defined in the file cp-demint.c.
67
68 This file also defines some other functions and variables which are
69 only to be used by the file cp-demint.c.
70
858b45cf
DD		 71 Preprocessor macros you can define while compiling this file:
72
73 IN_LIBGCC2
208c1674 74 If defined, this file defines the following functions, q.v.:
858b45cf
DD		 75 char *__cxa_demangle (const char *mangled, char *buf, size_t *len,
76 int *status)
208c1674
DD		 77 int __gcclibcxx_demangle_callback (const char *,
78 void (*)
79 (const char *, size_t, void *),
80 void *)
81 instead of cplus_demangle_v3[_callback]() and
82 java_demangle_v3[_callback]().
858b45cf
DD		 83
84 IN_GLIBCPP_V3
208c1674
DD		 85 If defined, this file defines only __cxa_demangle() and
86 __gcclibcxx_demangle_callback(), and no other publically visible
87 functions or variables.
858b45cf
DD		 88
89 STANDALONE_DEMANGLER
90 If defined, this file defines a main() function which demangles
91 any arguments, or, if none, demangles stdin.
92
93 CP_DEMANGLE_DEBUG
94 If defined, turns on debugging mode, which prints information on
95 stdout about the mangled string. This is not generally useful.
d81bf7dd
MM		 96
97 CHECK_DEMANGLER
98 If defined, additional sanity checks will be performed. It will
99 cause some slowdown, but will allow to catch out-of-bound access
100 errors earlier. This macro is intended for testing and debugging. */
