We give preference to printing <optimized out> rather
|
||
|
|
than <unavailable>, since if a value had been optimized out
|
||
|
|
at compile time, it can never be collected at run-time.
|
||
|
|
|
||
|
|
it seems it is just reversed, that 'unavailable' can exist only for
|
||
|
|
!optimized_out and it cannot exist for for optimized_out values.

It PASSes now even in gdbserver mode.
