and for thread_alive change from a couple weeks ago.
(extended_remote_ops): Declare and define a new target vector
for the extended remote protocol.
(extended_remote_restart): New function to restart the remote
server & process.
(remote_open): Just a stub routine.
(extended_remote_open): New function to start a remote session
using the extended gdb remote protocol.
(remote_open_1): New function containing code common to both
remote_open and extended_remote_open.
(remote_mourn, extended_remote_mourn, remote_mourn_1): Similarly.
(extended_remote_create_inferior): New function for the extended
remote target.
(initialize_remote): Add the extended_remote_ops target vector.
* gdbserver/server.c (main, case '!'): Set extended_protocol.
(main, case 'k'): If the extended protocol is in use, kill the
inferior then start a new one.
(main, case 'R'): New command to restart the remote server and
inferior process. Only supported when using the extended
protocol.
(main, server loop): If the inferior terminates while using the
extended protocol then start a new one. If getpkt fails when
using the extended protocol then exit.
New extended remote gdb protocol support; intended mainly for use with
the gdbserver testing framework that I'll be checking in soon. Also
useful for interactive remote debugging since it supports "run".
gdb tests (step.exp and step2.exp).
* config/mt-lynx (STEP_EXECUTABLE): Define.
(THREADFLAGS): Define.
Hiro's test for 6100 and a crude test of my own. They both need some
major cleanup for non-lynx hosts; both are also a little too loose in
their checks. But I'm too burnt out on lynx to address either concern.
further notice.
Looks like a bug in the lynx2.2.2 kernel scroggs the stack pointer in
these tests leading to massive failures. I've sent a nice small concise
example to Mark Rome @ lynx. Severe braindamage.
* sysdump.c (fillup): Return size - 1, the last byte is a checksum
and shouldn't be counted.
* sysroff.info (hd): Changed segment identifier from a byte to a 1
bit field. The sysroff 2.0-01 specification seems to be in error
here. Reduce width of following "spare" field from 4 to 3 bits.

to sysroff specification.

compiler from optimizing them away.

it to the thread list. Handle case where multi-threaded process
reverts back to a single-threaded process.
