This main idea behind this patch is this change to xml-support.c:scope_level- /* Body text accumulation. This is an owning pointer. */ - struct obstack *body; + /* Body text accumulation. */ + std::string body; ... which allows simplifying other parts of the code. In target_fetch_description_xml, we want to distinguish between returning "success + empty std::string" and "no success", and gdb::optional is a natural fit for that.
When growing a string like that, isn't it more efficient to use a stringstream?
