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 | Preprocessor macros you can define while compiling this file: | |
49 | ||
50 | IN_LIBGCC2 | |
51 | If defined, this file defines the following function, q.v.: | |
52 | char *__cxa_demangle (const char *mangled, char *buf, size_t *len, | |
53 | int *status) | |
54 | instead of cplus_demangle_v3() and java_demangle_v3(). | |
55 | ||
56 | IN_GLIBCPP_V3 | |
57 | If defined, this file defines only __cxa_demangle(). | |
58 | ||
59 | STANDALONE_DEMANGLER | |
60 | If defined, this file defines a main() function which demangles | |
61 | any arguments, or, if none, demangles stdin. | |
62 | ||
63 | CP_DEMANGLE_DEBUG | |
64 | If defined, turns on debugging mode, which prints information on | |
65 | stdout about the mangled string. This is not generally useful. | |
