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) | |
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. | |
