Use from a python pretty-printer is a bit convoluted, but it works:
def to_string(self):
gdb.set_convenience_variable('_tmp', self.val.reference_value())
return gdb.parse_and_eval('$_tmp.str()')

--- Comment #4 from Sourceware Commits <cvs-commit at gcc dot gnu.org> ---
The master branch has been updated by Hannes Domani <ssbssa@sourceware.org>:
https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;h=2e08907d0672711617f71ef4604df190106b992e
commit 2e08907d0672711617f71ef4604df190106b992e
Author: Hannes Domani <ssbssa@yahoo.de>
Date: Thu Feb 8 20:09:25 2024 +0100
Allow calling of C++ methods from python
Currently it's not possible to call C++ methods from python.
Using this example:
```
class B
{
static int static_func ();
int arg0_func ();
int arg1_func (int arg1);
int arg2_func (int arg1, int arg2);
};
B *b_obj = new B;
```
Trying to call B::static_func gives this error:
```
(gdb) py b_obj = gdb.parse_and_eval('b_obj')
(gdb) py print(b_obj['static_func']())
Traceback (most recent call last):
File "<string>", line 1, in <module>
RuntimeError: Value is not callable (not TYPE_CODE_FUNC).
Error while executing Python code.
```
TYPE_CODE_METHOD was simply missing as a possible type in
valpy_call, now the same is possible:
```
(gdb) py b_obj = gdb.parse_and_eval('b_obj')
(gdb) py print(b_obj['static_func']())
1111
```
Note that it's necessary to explicitely add the this pointer
as the first argument in a call of non-static methods:
```
(gdb) py print(b_obj['arg0_func']())
Traceback (most recent call last):
File "<string>", line 1, in <module>
gdb.error: Too few arguments in function call.
Error while executing Python code.
(gdb) py print(b_obj['arg0_func'](b_obj))
198
```
