* (unwind_command): Clean it up and make it print things out nicer. * monitor.c: Add ^C handling capability (mostly ripped off from remote.c). * (monitor_printf): Make it check the command echo. * (monitor_printf_noecho): Similar to above, but doesn't check for echo. * (monitor_stop): No longer waits for prompt. That is the job of the caller. This makes things work much better for monitor_wait, which waits for the prompt itself. * (monitor_open): Deal with new monitor_stop semantics. Also, flush input after sending init strings to get rid of junk that may be output. Also, don't always send \r to remote. Use monitor_ops->line_term cuz proper character isn't always \r. * (monitor_fetch_register): Switch to completely different algorithm to deal with lame-ass monitors which put spaces in the middle of numbers, and prompt with a space!!!!! * (monitor_read_memory_single): New routine to be used with monitors that can only return one byte/short/long at a time. This is selected via MO_GETMEM_READ_SINGLE. * (monitor_load_srec): Use monitor_printf_noecho for sending S records. Most targets don't echo them. * (monitor.h): Get rid of cmd_delim. Add line_delim. * op50n-rom.c (op50n_cmds): Fill it up. Make it work. * w89k-rom.c: Change all eols from \r to \n. Change load_resp to ^Q to prevent error message. * config/pa/tm-hppa.h (CALL_DUMMY (for hppro)): Add special instruction sequence at end to make restore_pc_queue happy.
