3fbdd5366e Make the /proc support a target-struct in its own right.
* inferior.h (proc_wait, inferior_proc_init, proc_set_exec_trap):
No longer global functions.
(fork_inferior):  New global function from fork-child.c.
* inftarg.c (child_wait):  Remove USE_PROC_FS conditional.
(ptrace_me, ptrace_him):  New stub functions for fork_inferior().
(child_create_inferior):  Moved to fork-child.c as fork_inferior.
(child_create_inferior):  New tiny function that calls fork_inferior.
* fork-child.c:  New file, containing fork_inferior, which is
built from slight mods to inftarg.c's child_create_inferior.

* procfs.c (procfs_ops):  Add target vector.
(attach):  Rename as static do_attach.
(procfs_create_inferior):  New tiny function that calls fork_inferior.
(child_xfer_memory):  Rename to static procfs_xfer_memory.
(store_inferior_registers):  Rename to static procfs_store_registers.
(inferior_proc_init):  Rename to static procfs_init_inferior.
(procfs_attach, procfs_detach, procfs_prepare_to_store,
procfs_files_info, procfs_open, procfs_mourn_inferior,
procfs_can_run):  Slightly mangled copies of the corresponding
child_XXX routines from inftarg.c.
(proc_wait):  Renamed to static procfs_wait.
(child_resume):  Rename to static procfs_resume.
(fetch_inferior_registers):  Rename to static procfs_fetch_registers.
(initialize_proc_fs):  Rename to initialize_procfs.  Set up
procfs_ops, too.
* xm-irix4.h, xm-sysv4.h (CREATE_INFERIOR_HOOK):  No longer needed.

b28d361723 Remove kill_inferior_fast, in favor of target_kill, which goes
through the target vector.

* inferior.h (kill_inferior_fast): remove declaration.

* main.c (disconnect): call quit_cover using catch_errors rather
than calling kill_inferior_fast directly.  New way goes through
the target vector, handles attached processes, and writes
command history if appropriate.
(quit_cover): new function, wrapper for quit_command.

* convex-xdep.c, go32-xdep.c, hppabsd-xdep.c, hppahpux-xdep.c,
infptrace.c, procfs.c:  Removed all instances of kill_inferior_fast,
inlining them into the local kill_inferior when needed.

34da36088e * procfs.c (proc_wait): Call print_sys_errmsg() if we get an
error from PIOCSWSTOP.

ec8ceca3f3 * buildsym.c (finish_block): Fix thinko `inner block' complaints.
* dbxread.c (process_one_symbol):  Parse N_OPT "gcc2_compiled.".
* procfs.c (proc_set_exec_trap): Set run-on-last-close flag on
child processes, to avoid dead ones "hanging around" after GDB exits.
(attach): Always stop the process if it needs it.  Set RLC flag
when attaching running processes, so it will continue if we detach
it, quit, or are killed.
(detach):  Clear faults and set RLC flag to make process run
when we close it.
(open_proc_file):  New `mode' argument for O_RDONLY or O_RDWR.
Callers changed.
(info_proc):  Open process O_RDONLY, so we can see any process,
even those controlled by debuggers.
* tm-sun4sol2.h (SUN_FIXED_LBRAC_BUG):  They did (in Sol 2).

4ace50a510 Remove now obsolete signame.c and signame.h; functionality is handled by
libiberty/strsignal.c.  Widespread changes to use libiberty/strerror.c
functions for errno manipulations and libiberty/strsignal.c for signo
(signals) manipulations.

5c1c5e6745 Fix bug in values.c unpacking signed characters on hosts where the default
character type is unsigned.  Add some cases to the tables in procfs.c
for constants defined in newer SVR4 systems and reorder the tests for
ioctl support of resetting the inherit-on-fork flag to favor the latest
method using PIOCRESET.

cc221e76d6 Many changes to procfs.c, mostly to expand the "info proc" command and to
fix a couple of small bugs.  Changes to other files mostly to fix minor
things pointed out by the SGI compiler.  See ChangeLog for complete details.

processing, broken by other recent changes.

* All GDB files that #include defs.h: Removed stdio.h.
	(defs.h): #include stdio.h.

This has been tested by building GDBs for all targets hosted on Sun4.
None of the build problems were related to stdio.h inclusion.  (n.b.
many configurations don't build for other reasons.)

a39ad5ce42 Many small changes to procfs.c to add base support for a new "info proc"
command that prints /proc specific information, changes to solib.c to
allow more flexible handling of finding the dynamic linker structures,
changes to utils.c and defs.h to add a new null_cleanup() function to
serve as an anchor point for cleanup chains with no obvious "first
cleanup".
