Fix accessing a method's fields from Python
Considering this example:
struct C
{
int func() { return 1; }
} c;
int main()
{
return c.func();
}
Accessing the fields of C::func, when requesting the function by its
type, works:
(gdb) py print(gdb.parse_and_eval('C::func').type.fields()[0].type)
C * const
But when trying to do the same via a class instance, it fails:
(gdb) py print(gdb.parse_and_eval('c')['func'].type.fields()[0].type)
Traceback (most recent call last):
File "<string>", line 1, in <module>
TypeError: Type is not a structure, union, enum, or function type.
Error while executing Python code.
The difference is that in the former the function type is TYPE_CODE_FUNC:
(gdb) py print(gdb.parse_and_eval('C::func').type.code == gdb.TYPE_CODE_FUNC)
True
And in the latter the function type is TYPE_CODE_METHOD:
(gdb) py print(gdb.parse_and_eval('c')['func'].type.code == gdb.TYPE_CODE_METHOD)
True
So this adds the functionality for TYPE_CODE_METHOD as well.
