/* Under some ABI's that specify the `struct convention' for returning
structures by value, by the time we've returned from the function,
the return value is sitting there in the caller's buffer, but GDB
has no way to find the address of that buffer.
On such architectures, use this function as your
extract_struct_value_address method. When asked to a struct
returned by value in this fashion, GDB will print a nice error
message, instead of garbage. */
