* blockframe.c (get_prev_frame_info): If FRAME_CHAIN_COMBINE returns 0, there is no previous frame. * breakpoint.c (commands_command): If !from_tty, don't call input_from_terminal_p(). * dbxread.c (record_misc_function): Speed up slightly. (compare_psymbols): Ditto. * infcmd.c (do_registers_info): Take a second argument to determine whether to print float registers. "info registers" does not do so anymore. "info all-registers" does, now. * mips-tdep.c, pyr-tdep.c (xxx_do_registers_info): Take second arg and ignore it. * tm-mips.h, tm-pyr.h (DO_REGISTERS_INFO): Pass second arg. * inflow.c (initialize_inflow): Set tflags_ours correctly.
