# GDB's output here, not the server's output. And while we could read
|
|
# GDBserver's output from $inferior_spawn_id, having GDBserver print
|
|
# the warnings on its terminal doesn't really help users. Much better
|
|
# would be to extend the remote protocol to let the server tell GDB
|
|
# which memory range couldn't be accessed, and then let GDB print the
|
|
# warning instead of the server. See PR gdb/22293.)
