| 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. |
