|
||||
* monitor.c (monitor_debug): Take prefix, and suffix arguments.
|
||||
Print trailing newline after the suffix.
|
||||
(monitor_printf{,_noecho}): Change monitor_debug calls.
|
||||
(monitor_printf): Call monitor_expect instead of trying to do the
|
||||
expect processing locally so that if there is extra junk, it
|
||||
doesn't hang things up.
|
||||
(readchar): If MO_HANDLE_NL is set, handle \r\n pairs and convert
|
||||
them to a single \r. Use monitor_debug to print out byte read.
|
||||
|
||||
* monitor.h (MO_HANDLE_NL): Add new flag.
|
||||
|
||||
* ppcbug-rom.c (ppcbug_ops{1,2}): Split into two ops, one that
|
||||
uses lo 0 to load, and the other that uses lo 1. Set flag
|
||||
MO_HANDLE_NL.
|
||||
(ppcbug_open{0,1}): Clone and split to handle ppcbug_ops{1,2}.
|
||||
(_initialize_ppcbug_rom): Set up both ppcbug_open{0,1}.

||||

||||
|
||||
* defs.h: Delete extraneous whitespace at end of file.
