* 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.
basis. See comments in objfiles.h and details in ChangeLog. Also remove
redundant definitions of FRAME_CHAIN_VALID from most of the tm-* files and
use a default definition in frame.h.
defining CALL_DUMMY_LOCATION as BEFORE_TEXT_END. This is
because machines that do this will also have to know to
set NEED_TEXT_START_END. Besides, it was a redundant way to
say the same thing.
* tm-29k.h, tm-convex.h, tm-np1.h: Eliminate
CANNOT_EXECUTE_STACK, define CALL_DUMMY_LOCATION and
NEED_TEXT_START_END.
Allow the register definitions to be overridden in another
tm-file. Fix SR_REGNUM. Add a mess of _REGNUM's. Separate
RETURN_REGNUM from GR96_REGNUM and DUMMY_SAVE_GREGS from
DUMMY_SAVE_GR96, for handling kernel calling conventions
that use GR64+ rather than GR96+.
