Change to rely on PIDGET etc.
* config/i386/nm-i386sol2.h (TARGET_HAS_WATCHPOINTS,
TARGET_CAN_USE_HARDWARE_WATCHPOINT, HAVE_CONTINUABLE_WATCHPOINT,
STOPPED_BY_WATCHPOINT, target_[insert/remove]_watchpoint):
define. Allow target to use procfs hardware watchpoints.
* config/sparc/nm-sun4sol2.h: ditto.
* config/i386/tm-i386sol2.h (PIDGET, TIDGET, MERGEPID): modify
definitions to use 16 bits for the pid, 15 bits for the tid, and
1 bit for the flag.
* config/sparc/tm-sun4sol2.h: ditto.
(SOFTWARE_SINGLE_STEP, SOFTWARE_SINGLE_STEP_P): undefine.
* testsuite/gdb.threads/pthreads.exp (all_threads_running): Allow
for more than 15 thread increments.
config/sparc/nm-sun4sol2.h config/sparc/sun4sol2.mh
config/sparc/tm-sun4sol2.h: Use autoconf to config Solaris thread
and pthread support, since pre-2.5 systems don't come with
libthread_db.so.1.
* procfs.c (info_proc): Use int instead of id_t. Old versions of
Irix don't see to define this.
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.
* config/sparc/nm-nbsd.h (CHILD_PREPARE_TO_STORE): Move to here
from config/sparc/xm-nbsd.h.
* config/sparc/nm-sun4os4 (CHILD_PREPARE_TO_STORE): Ditto, from
config/sparc/xm-sparc.h.
* config/sparc/nm-sun4sol2.h: New file, renamed from nm-sysv4.h.
(PRSVADDR_BROKEN): Move here from xm-sun4sol2.h.
* config/sparc/sun4sol2.mh (NAT_FILE): Update.
* config/sparc/xm-sun4os4.h (HAVE_TERMIOS): Remove.
