process will be the default target.
* target.c (find_default_run_target, find_default_attach,
find_default_create_inferior, return_zero): new functions.
(cleanup_target): Make return_zero the default for to_can_run.
* exec.c (exec_ops), core.c (core_ops): Replace child_attach and
child_create_inferior references with find_default_XXX instead.
* target.h (struct target_ops): new field, to_can_run.
(find_default_attach, find_default_create_inferior): new prototypes.
(target_can_run): new macro.
* Also added a zero (default) to_can_run element to all static
struct target_ops initializations throughout GDB, except:
* inftarg.c (child_ops): Use new child_can_run() to enable child runs.
* infrun.c (child_create_inferior): Clean up error handling when
no exec file is specified.
(child_attach): Don't require exec file.
29k-share/dfe/yank.c, vx-share/xdr_ptrace.c, vx-share/xdr_regs.c:
Remove -I29k-share, -Ivx-share from Makefile.in. Make #includes
relative to each source file.
* 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.
