No, I won't. I found that my patch missed the calls of using_struct_return
in eval.c. These calls only happen in case of a OP_OBJC_MSGCALL operation.
At line 841 in eval.c, in function evaluate_subexp_standard() I found this:
/* If we found a method with symbol information, check to see
if it returns a struct. Otherwise assume it doesn't. */
if (method)
{
[...]
struct_return = using_struct_return (value_type, using_gcc);
}
else if (expect_type != NULL)
{
struct_return = using_struct_return (check_typedef (expect_type), using_gcc);
}
While the `if (method)' branch is simple, the `else if' branch can't be
solved easily. evaluate_subexp_standard just gets the expected return type
as parameter.
Does anybody know how to get around this problem? For now I can only see
one way, redefine gdbarch_return_value to get both, function type and return
value type.
