New option "set print symbol-loading".
* NEWS: Mention it. * solib.c (solib_read_symbols): Only print symbol loading messages if requested. (solib_add): If symbol loading is in "brief" mode, notify user symbols are being loaded. (reload_shared_libraries_1): Ditto. * symfile.c (print_symbol_loading_off): New static global. (print_symbol_loading_brief): New static global. (print_symbol_loading_full): New static global. (print_symbol_loading_enums): New static global. (print_symbol_loading): New static global. (print_symbol_loading_p): New function. (symbol_file_add_with_addrs): Only print symbol loading messages if requested. (_initialize_symfile): Register "print symbol-loading" set/show command. * symfile.h (print_symbol_loading_p): Declare. doc/ * gdb.texinfo (Symbols): Document set/show print symbol-loading. testsuite/ * gdb.base/print-symbol-loading-lib.c: New file. * gdb.base/print-symbol-loading-main.c: New file. * gdb.base/print-symbol-loading.exp: New file.
