Fix from maj@lucid.com.
* remote-udi.c (udi_open): Reset vars so that user can re-run
programs without leaving GDB.
* (many routines): Slightly improve error handling.
* (download): Zero out BSS by longs instead of bytes to avoid
timeouts in real hardware.
* 29k-share/udi/udip2soc.c (UDIDisconnect, UDIKill): Indicate
that connection is no longer in use after shutdown() of socket.
This keeps GDB from dying of a SIGPIPE when you issue multiple
`target udi' commands.
* am29k-tdep.c: Update to latest code from AMD.
(get_saved_register) don't crap out if no frame.
* remote-udi.c: Set/clear inferior_pid as appropriate.
(udi_open) call target_preopen, don't close fd 0!!!, clean up
error handling. Fixup end-of-debugging messages.
(udi_fetch_registers) clean up big time, mainly don't multiply
register_valid indices by 4, and use proper Offset when reading
gr96-gr127. (udi_store_registers) general cleanup.
(fetch_register) cleanup, simplify. (regnum_to_srnum)
INT_REGNUM->INTE_REGNUM.
* tm-29k.h: Upgrade to latest code from AMD.
* 29k-share/udi/udip2soc.c: Get rid of useless errmsg_m macro.
(UDIConnect) Clean up error processing (like, don't do exit() if
execlp fails), make code restartable, make more attractive.
(UDIStop) Use SIGINT instead of SIGUSR1, as isstip won't stop
otherwise.
