DD		 31/* This code implements a demangler for the g++ V3 ABI. The ABI is
32 described on this web page:
e9301e76 33 https://itanium-cxx-abi.github.io/cxx-abi/abi.html#mangling
858b45cf
DD		 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)
208c1674
DD		 45 int cplus_demangle_v3_callback(const char *mangled, int options,
46 demangle_callbackref callback)
47 int java_demangle_v3_callback(const char *mangled,
48 demangle_callbackref callback)
858b45cf
DD		 49 enum gnu_v3_ctor_kinds is_gnu_v3_mangled_ctor (const char *name)
50 enum gnu_v3_dtor_kinds is_gnu_v3_mangled_dtor (const char *name)
51
59727473
DD		 52 Also, the interface to the component list is public, and defined in
53 demangle.h. The interface consists of these types, which are
54 defined in demangle.h:
55 enum demangle_component_type
56 struct demangle_component
208c1674 57 demangle_callbackref
59727473
DD		 58 and these functions defined in this file:
59 cplus_demangle_fill_name
60 cplus_demangle_fill_extended_operator
61 cplus_demangle_fill_ctor
62 cplus_demangle_fill_dtor
63 cplus_demangle_print
208c1674 64 cplus_demangle_print_callback
59727473
DD		 65 and other functions defined in the file cp-demint.c.
66
67 This file also defines some other functions and variables which are
68 only to be used by the file cp-demint.c.
69
858b45cf
DD		 70 Preprocessor macros you can define while compiling this file:
71
72 IN_LIBGCC2
208c1674 73 If defined, this file defines the following functions, q.v.:
858b45cf
DD		 74 char *__cxa_demangle (const char *mangled, char *buf, size_t *len,
75 int *status)
208c1674
DD		 76 int __gcclibcxx_demangle_callback (const char *,
77 void (*)
78 (const char *, size_t, void *),
79 void *)
80 instead of cplus_demangle_v3[_callback]() and
81 java_demangle_v3[_callback]().
858b45cf
DD		 82
83 IN_GLIBCPP_V3
208c1674
DD		 84 If defined, this file defines only __cxa_demangle() and
85 __gcclibcxx_demangle_callback(), and no other publically visible
86 functions or variables.
858b45cf
DD		 87
88 STANDALONE_DEMANGLER
89 If defined, this file defines a main() function which demangles
90 any arguments, or, if none, demangles stdin.
91
92 CP_DEMANGLE_DEBUG
93 If defined, turns on debugging mode, which prints information on
94 stdout about the mangled string. This is not generally useful.
d81bf7dd
MM		 95
96 CHECK_DEMANGLER
97 If defined, additional sanity checks will be performed. It will
98 cause some slowdown, but will allow to catch out-of-bound access
99 errors earlier. This macro is intended for testing and debugging. */
