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. gdb/ChangeLog: 2017-04-18 Pedro Alves <palves@redhat.com> * tracefile-tfile.c (tfile_write_tdesc): Adjust to use gdb::optional<std::string>. * xml-support.c: Include <string>. (scope_level::scope_level(scope_level &&)) (scope_level::~scope_level): Delete. (scope_level::body): Now a std::string. (gdb_xml_body_text, gdb_xml_end_element): Adjust. (xinclude_parsing_data::xinclude_parsing_data): Add 'output' parameter. (xinclude_parsing_data::~xinclude_parsing_data): Delete. (xinclude_parsing_data::output): Now a std::string reference. (xinclude_start_include): Adjust. (xml_xinclude_default): Adjust. (xml_process_xincludes): Add 'output' parameter, and return bool. * xml-support.h (xml_process_xincludes): Add 'output' parameter, and return bool. * xml-tdesc.c: Include <unordered_map> and <string>. (tdesc_xml_cache): Delete. (tdesc_xml_cache_s): Delete. (xml_cache): Now an std::unordered_map. (tdesc_parse_xml): Adjust to use std::string and unordered_map. (target_fetch_description_xml): Change return type to gdb::optional<std::string>, and adjust. * xml-tdesc.h: Include "common/gdb_optional.h" and <string>. (target_fetch_description_xml): Change return type to gdb::optional<std::string>.
