With dummy_frame destructors GDB no longer has to use global stop_registers. dummy_frame's registers can be now stored associated with their specific dummy_frame. gdb/ChangeLog 2015-05-13 Jan Kratochvil <jan.kratochvil@redhat.com> * infcall.c (struct dummy_frame_context_saver) (dummy_frame_context_saver_data_free, dummy_frame_context_saver_dtor) (dummy_frame_context_saver_drop, dummy_frame_context_saver_cleanup) (dummy_frame_context_saver_get_regs, dummy_frame_context_saver_setup): New. (call_function_by_hand_dummy): Move discard_cleanups of inf_status_cleanup before dummy_frame_push. Call dummy_frame_context_saver_setup and prepare context_saver_cleanup. Use dummy_frame_context_saver_get_regs instead of stop_registers. * infcall.h (struct dummy_frame_context_saver) (dummy_frame_context_saver_drop, dummy_frame_context_saver_cleanup) (dummy_frame_context_saver_get_regs, dummy_frame_context_saver_setup): New declarations. * infcmd.c: Include infcall.h. (get_return_value): Add parameter ctx_saver, use it instead of stop_registers. (print_return_value): Add parameter ctx_saver, pass it. (struct finish_command_continuation_args): Add field ctx_saver. (finish_command_continuation): Update print_return_value caller. (finish_command_continuation_free_arg): Free also ctx_saver. (finish_forward): Call dummy_frame_context_saver_setup. * inferior.h (struct dummy_frame_context_saver): New declaration. (get_return_value): Add parameter ctx_saver. * python/py-finishbreakpoint.c (bpfinishpy_pre_stop_hook): Update get_return_value caller.
