+
+ * hppa-tdep.c (read_unwind_info): Cosmetic cleanup.
+ * (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.
