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 | 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 | ||||
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 | |||
73 | If defined, this file defines only __cxa_demangle(), and no other | |||
74 | publically visible functions or variables. | |||
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. | |||
