| 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) |
| 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) |
| 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 | |
| 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 |
| 58 | demangle_callbackref |
| 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 |
| 65 | cplus_demangle_print_callback |
| 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 | |
| 71 | Preprocessor macros you can define while compiling this file: |
| 72 | |
| 73 | IN_LIBGCC2 |
| 74 | If defined, this file defines the following functions, q.v.: |
| 75 | char *__cxa_demangle (const char *mangled, char *buf, size_t *len, |
| 76 | int *status) |
| 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](). |
| 83 | |
| 84 | IN_GLIBCPP_V3 |
| 85 | If defined, this file defines only __cxa_demangle() and |
| 86 | __gcclibcxx_demangle_callback(), and no other publically visible |
| 87 | functions or variables. |
| 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. |
