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 |
||
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. |
