This changes the exception's "message" member to be a shared_ptr wrapping a std::string. This allows removing the stack of exception messages, because now exceptions will self-destruct when needed. This also adds a noexcept copy constructor and operator= to gdb_exception, plus a "what" method. gdb/ChangeLog 2019-04-08 Tom Tromey <tom@tromey.com> * xml-support.c (gdb_xml_parser::parse): Update. * x86-linux-nat.c (x86_linux_nat_target::enable_btrace): Update. * value.c (show_convenience): Update. * unittests/cli-utils-selftests.c (test_number_or_range_parser) (test_parse_flags_qcs): Update. * thread.c (thr_try_catch_cmd): Update. * target.c (target_translate_tls_address): Update. * stack.c (print_frame_arg, read_frame_local, read_frame_arg) (info_frame_command_core, frame_apply_command_count): Update. * rust-exp.y (rust_lex_exception_test): Update. * riscv-tdep.c (riscv_print_one_register_info): Update. * remote.c (remote_target::enable_btrace): Update. * record-btrace.c (record_btrace_enable_warn): Update. * python/py-utils.c (gdbpy_convert_exception): Update. * printcmd.c (do_one_display, print_variable_and_value): Update. * mi/mi-main.c (mi_print_exception): Update. * mi/mi-interp.c (mi_cmd_interpreter_exec): Use SCOPE_EXIT. * mi/mi-cmd-stack.c (list_arg_or_local): Update. * linux-nat.c (linux_nat_target::attach): Update. * linux-fork.c (class scoped_switch_fork_info): Update. * infrun.c (displaced_step_prepare): Update. * infcall.c (call_function_by_hand_dummy): Update. * guile/scm-exception.c (gdbscm_scm_from_gdb_exception): Update. * gnu-v3-abi.c (print_one_vtable): Update. * frame.c (get_prev_frame_always): Update. * f-valprint.c (info_common_command_for_block): Update. * exec.c (try_open_exec_file): Update. * exceptions.c (print_exception, exception_print) (exception_fprintf, exception_print_same): Update. * dwarf2-frame.c (dwarf2_build_frame_info): Update. * dwarf-index-cache.c (index_cache::store) (index_cache::lookup_gdb_index): Update. * darwin-nat.c (maybe_cache_shell): Update. * cp-valprint.c (cp_print_value_fields): Update. * compile/compile-cplus-symbols.c (gcc_cplus_convert_symbol) (gcc_cplus_symbol_address): Update. * compile/compile-c-symbols.c (gcc_convert_symbol) (gcc_symbol_address, generate_c_for_for_one_variable): Update. * common/selftest.c: Update. * common/common-exceptions.h (struct gdb_exception) <message>: Now a std::string.
