/* This file implements demangling of C++ names mangled according to |
/* This code implements a demangler for the g++ V3 ABI. The ABI is |

http://www.codesourcery.com/cxx-abi/abi.html#mangling |
34 |
STANDALONE_DEMANGLER defined to create a demangling filter |
|
35 |
executable (functionally similar to c++filt, but includes this |
This code was written while looking at the demangler written by |
36 |
demangler only). */ |
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. |
