RE: [PATCH v6] Change message when reaching end of reverse history.

["Metzger, Markus T" <markus.t.metzger@intel.com>]

Hello Alex,

>> In a record session, when we move backward, GDB switches from normal
>> execution to simulation. Moving forward again, the emulation continues
>> until the end of the reverse history. When the end is reached, the
>> execution stops, and a warning message is shown. This message has been
>> modified to indicate that the forward emulation has reached the end, but
>> the execution can continue as normal, and the recording will also continue.
>>
>> Before this patch, the warning message shown in that case was the same as
>> in the reverse case. This meant that when the end of history was reached in
>> either backward or forward emulation, the same message was displayed:
>>
>> "No more reverse-execution history."
>>
>> This message has changed for these two cases. Backward emulation:
>>
>> "Reached end of recorded history; stopping.
>> Backward execution from here not possible."
>>
>> Forward emulation:
>>
>> "Reached end of recorded history; stopping.
>> Following forward execution will be added to history."
>>
>> The reason for this change is that the initial message was deceiving, for
>> the forward case, making the user believe that forward debugging could not
>> continue.
