This is just a minor cleanup of an ARI violation. As this affects
code that is normally unreachable (you'd need a runtime where
the unit providing the exception hook has been compiled without
debugging information), I tested this manually by commenting out
the code just above, thus forcing this part of the code to be
exercised.
gdb/ChangeLog:
* ada-lang.c (print_it_exception): Avoid use of sprintf.
Tested on x86_64-linux.
gdb/
* infrun.c (resume): Mention which is the current thread, and its
current PC in debug output.
(prepare_to_proceed): Mention the thread switching in debug
output.
gdb/doc/
* gdb.texinfo (Remote Protocol) <Overview>: Mention vCont is
required for multi-threading support.
(Remote Protocol) <Packets>: Mention that 'c', 's', 'C', 'S' and
Hc are deprecated for multi-threading debugging. Point readers at
the vCont packet.
