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 | ||
59727473 DD |
48 | Also, the interface to the component list is public, and defined in |
49 | demangle.h. The interface consists of these types, which are | |
50 | defined in demangle.h: | |
51 | enum demangle_component_type | |
52 | struct demangle_component | |
53 | and these functions defined in this file: | |
54 | cplus_demangle_fill_name | |
55 | cplus_demangle_fill_extended_operator | |
56 | cplus_demangle_fill_ctor | |
57 | cplus_demangle_fill_dtor | |
58 | cplus_demangle_print | |
59 | and other functions defined in the file cp-demint.c. | |
60 | ||
61 | This file also defines some other functions and variables which are | |
62 | only to be used by the file cp-demint.c. | |
63 | ||
858b45cf DD |
64 | Preprocessor macros you can define while compiling this file: |
65 | ||
66 | IN_LIBGCC2 | |
67 | If defined, this file defines the following function, q.v.: | |
68 | char *__cxa_demangle (const char *mangled, char *buf, size_t *len, | |
69 | int *status) | |
70 | instead of cplus_demangle_v3() and java_demangle_v3(). | |
71 | ||
72 | IN_GLIBCPP_V3 | |
59727473 DD |
73 | If defined, this file defines only __cxa_demangle(), and no other |
74 | publically visible functions or variables. | |
858b45cf DD |
75 | |
76 | STANDALONE_DEMANGLER | |
77 | If defined, this file defines a main() function which demangles | |
78 | any arguments, or, if none, demangles stdin. | |
79 | ||
80 | CP_DEMANGLE_DEBUG | |
81 | If defined, turns on debugging mode, which prints information on | |
82 | stdout about the mangled string. This is not generally useful. | |
