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. | |
