This introduces gdb_dlhandle_up, a unique_ptr that can close a dlopen'd library. All the functions working with dlopen handles are updated to use this new type. I did not try to build this on Windows. gdb/ChangeLog 2017-04-12 Tom Tromey <tom@tromey.com> * jit.c (struct jit_reader): Declare separately. Add constructor and destructor. Change type of "handle". (loaded_jit_reader): Define separately. (jit_reader_load): Update. New "new". (jit_reader_unload_command): Use "delete". * gdb-dlfcn.h (struct dlclose_deleter): New. (gdb_dlhandle_up): New typedef. (gdb_dlopen, gdb_dlsym): Update types. (gdb_dlclose): Remove. * gdb-dlfcn.c (gdb_dlopen): Return a gdb_dlhandle_up. (gdb_dlsym): Change type of "handle". (make_cleanup_dlclose): Remove. (dlclose_deleter::operator()): Rename from gdb_dlclose. * compile/compile-c-support.c (load_libcc): Update.
