returns a possibly modified pid.
* inftarg.c (ptrace_him): Now returns pid;
* m3-nat.c (m3_trace_him): Now returns pid;
* infcmd.c (run_command): Minor cleanup.
* infrun.c (wait_for_inferior): Add another check for one_stepped
near where we read the pc to avoid erroneously setting
random_signal for multi-threaded support.
* procfs.c: Add support for Solaris LWPs. Remove def of
LOSING_POLL. Many cleanups... Several workarounds for Solaris
lossage. System call entry and exit are now handled by
dynamically registered handlers.
* (syscallname): Don't barf when handed an unknown syscall
number.
* (info_proc_syscalls): Ditto.
* sol-thread.c: New file. Implements Solaris thread support.
* symfile.c (symbol_file_add): Add call to target_new_objfile to
notify target-dependent code about new symbol tables.
* (clear_symtab_users): Call target_new_objfile to notify it of
the removal of all symbol tables.
* target.c (push_target): Make sure that to_close is non-zero
before calling it.
* target.h (target_new_objfile): Provide default.
* config/alpha/nm-osf2.h: Define LOSING_POLL because this version
of OSF can't hack using poll with /proc.
* config/sparc/nm-sun4sol2.h (target_new_objfile): Define to be
sol-thread-new-objfile.
* config/sparc/sun4sol2.mh: Add sol-thread.o to NATDEFFILES, and
add libthread_db.so.1 to NAT_CLIBS.
* config/sparc/tm-sun4sol2.h: Define PIDGET, TIDGET, and
target_pid_to_str.
for OSF/1-3.x procfs support.
* configure.in (alpha-dec-osf): Use them when configuring
for OSF/1-3.x.
* configure: Updated.
* target.c: Include <string.h>.
vectors anymore.
* (unpush_target): Test for to_close being set before calling.
* (target_xfer_memory, target_info): Check for to_has_memory
before playing with memory.
* Add rule for annotate.o to keep Sun make happy.
* configure.in: Add config for powerpc/Netware.
* partial-stab.h (near N_SO): Don't call START_PSYMTAB with null
filename. This speeds up handling of trailing N_SO stabs (they
mark the end of a .o file).
* target.c, target.h: Change the way pushing and popping of
targets work to support target overlays and inheritance.
* corelow.c, hppa-tdep.c, inflow.c, remote-nindy.c, utils.c:
Fixup references to current_target, due to previous changes.
* config/i386/tm-i386nw.h: Enable longjmp support. More work is
needed to get the address of longjmp out of the target.
* inflow.c (job_control, attach_flag, generic_mourn_inferior):
Remove, needed for both native and cross.
* target.c (attach_flag, generic_mourn_inferior): Put here.
* utils.c (job_control): Put here.
(terminal.h): Don't include anymore.

Makefile.in configure.in
Added Files:
os9kread.c os9kstab.c remote-os9k.c
* os9kread.c: New file to read os9000 style symbo table.
* os9kstab.c: new file to read os9000 style stabs.
* remote-os9k.c: remote protocol talking to os9000 rombug monitor.
* objfiles.c (find_pc_objfile): new function to search objfile

* objfiles.c (objfile_relocate_data): new function to relocate
data symbols in symbol table.
* objfiles.h: Add two aux fields in struct objfile to handle
multiple symbol table files situation like in os9000.
* symfile.c: Change so 'symbol-file' command can handle multiple
files. Also call target_link() to get relocation infos.
* target.c (target_link): new function to get relocation info when
a symbol file is requested to load.
* main.c (quit_command): take out 'inferior_pid != 0' condition,
because in cross mode there's no inferior pid, bit they need to
be detached.
Makefile.in: add os9kread.c os9kstab.c and .o's.
configure.in: add i386os9k target.
config/i386/i386os9k.mt: new add.
config/i386/tm-i386os9k.h: new add.
caller. Put string in malloc'd space, so caller need not impose
arbitrary limits.
* solib.c (find_solib): Update to use new interface.
* irix5-nat.c (find_solib): Read o_path from inferior
(clear_solib): Free storage for o_path.

* fork-child.c, solib.c, hppa-tdep.c, osfsolib.c: Use this stuff.
* convex-xdep.c, convex-tdep.c: Add FIXME's (getting the Convex
signal code stuff right with the new signals would be non-trivial).
* inferior.h (stop_signal): Make it enum target_signal not int.
* target.c, target.h (target_signal_to_string, target_signal_to_name,
target_signal_from_name): New functions.

take advantage of gcc's builtin functions for increased performance.
* i386-tdep.c, main.c, valprint.c:
Replace bcmp() use with memcmp(), which is more standard and can
take advantage of gcc's builtin functions for increased performance.
elfread.c (coff_symfile_finish): Add function, prototype, and
add to the xxxx_sym_fns struct for each file type. Also reformat
the xxxx_sym_fns vector to a standard format and add comments.

elfread.c (xxx_symfile_new_init, xxx_symfile_init, xxx_symfile_read):
Pass pointer to struct objfile rather than pointer to sym_fns.
Change references inside each function accordingly. Allocate any

routine for the objfile before deallocating other stuff.
* sparc-tdep.c (get_longjmp_target): Cast target_read_memory arg.
* symfile.h: Move struct sym_fns to before struct objfile def.
Add sym_finish function pointer and change prototypes of other
function pointers to reflect passing struct objfile pointer rather
than struct sym_fns pointer.

* symfile.c (symfile_init): Renamed to find_sym_fns, and now only
locates the correct sym_fns struct for the given objfile.

(add_target): Call add_cmd and mess with targetlist->doc.
core.c, exec.c, remote-eb.c, remote-nindy.c, remote-vx.c,
